SPPAS Revision notes

SPPAS 1.x

Version 1.0

(2011, 9th March)

The only implemented feature was that the tool was able to perform speech segmentation of English read speech.

The tool was made only of tcsh and gawk scripts. It was developed under Linux, and was efficiently tested under Windows with Cygwin.

Version 1.1

(2011, 7th June)

This was mainly the debug of the previous version and some code re-organization and cleaning.

Version 1.2

(2011, 23th July)

The support of English, French and Italian was added: a lexicon, a pronunciation dictionary and an acoustic model of each language was created. The speech segmentation procedure was divided into three different annotations: Tokenization, Phonetization, Alignment.

The foundation is being laid for a multi-lingual methodology.

Version 1.3

(2011, 12th December)

This was a transitional version, from the script programming language to Python programming language. The main fixes and improvements were as follows.

Development:

• macOS support
• bugs corrected in many scripts
• check.csh -> check.py
• sppas.csh -> sppas.py
• GUI: zenity -> pyGtk
• the usage of sox is limited for re-sampling audio signal
• a python library to manage wav files is added.
• added IPUs segmentation automatic annotation

Resources:

• Italian dictionary improved
• Italian acoustic model changed (triphones trained from map-task dialogues)
• French acoustic model changed

But the tool still hasn’t a name and wasn’t distributed.

SPPAS 1.4.0

(2012, 14th June)

It’s the official birth of SPPAS. The software has a name, a license, a GUI, a web-page and is freely distributed to the community.

The source code is only based on Python 2.7.x language and the GUI is based on WxPython 2.8.x or 2.9.x (on macOS, it must be 32 bits). SPPAS requires also sox and julius software to be installed.

Automatic annotations:

• added Momel (MOdelling MELody) which is an algorithm developed by Daniel Hirst and Robert Espesser for the analysis and synthesis of intonation patterns. Momel needs a .hz files with pitch values: ASCII file with one value each 10ms. This implementation of Momel can be used directly, with a large set of options. Get options with: > python $SPPAS/scripts/lib/momel.py -h or in SPPAS GUI, or in text-mode (only with default options): > $SPPAS/sppas.py -i INPUT –momel
• added the first version of INTSINT, proposed by Daniel Hirst. INTSINT is an acronym for INternational Transcription System for INTonation. INTSINT codes the intonation of an utterance by means of an alphabet of i 8 discrete symbols constituting a surface phonological representation of the intonation.

Packaging:

• merged AUTHORS, VERSION and README files into the README file
• created packages in the lib directory
• ipu-segmentation re-implemented in python language
• improve ipu segmentation algorithm
• phonetization re-implemented in python, and added an unknown word phonetization algorithm
• alignment entirely re-implemented in python
• syllabification re-implemented with python, and tool/syllabify.py
• add a simple terminal controller (not needed for Unix, just for DOS)
• Momel can read PitchTier (from Praat) files
• Momel can deal with long sounds (not only one IPU)
• manage source files, comments, exceptions…
• SPPAS works as a single instance by mean of a lock file.
• SPPAS can be installed in a directory containing spaces and can deal with file names with spaces.

GUI:

• GUI with the wxpython library
• Manage a list of selected files
• Add a File information
• Add a Wav player
• Fix options to each annotation step with the menu
• Open the log file after each process

Resources:

• French dictionary is using UTF-8 (instead of iso8859-1 in previous versions)
• French dictionary is based on X-SAMPA phone set
• Chinese: deal with chinese characters instead of pinyin.

Known Bugs:

• The wav player can't play wav files if the filename contains #.
• The first line of the Italian dictionary must be changed to # [#] #.

Important The setup is now creating a Python Virtual Environment in the hidden folder .sppaspyenv~. Then, the setup has to be launched every time a new SPPAS package is installed. The sppas commands are launching the GUI with Python of this virtual environment.

Annotations

• Syllabification: a new option to output one more tier with syllable structures
• CuedSpeech: code cleaning and re-organization, two more tiers are created: HandShapes and HandPositions. They are predicting respectively the moments D1-D2 (change of shape) and M1-M2 (change of position). The prediction model is a set of rules based on the work described in (Attina, 2005), page 117 and page 136. It can export a video with badges moving and standing depending on this model, or with pictures of a hand when the debug logging level is set (in the .app~ file).
• FaceDetection: can choose the model(s) to enable or disable in the options. MediaPipe Face Detection is added to one of the possible recognizers - it’s very fast but results are worse than other models.
• FaceSights: MediaPipe Face Mesh is used to predict the 68 face sights (weight=6) interpolated with OpenCV LBF (weight=1). No longer use of the DAT model nor the empirical sights.
• PersonFaceIdentity: A new filter is added to remove unrelevant known identified persons, when number of stored images is less than 1/3 of the expected ones. Added options: mincoords, minrefcoords, mindistcoords, mindistimgs, nbfrimg. And now, the person is identified with the automatic face recognizer first, then with the coordinates instead of the contrary.

GUI

• Page Edit: new buttons in the player control panel to play one frame of a video in both ways (next or previous frame)
• Page Files: a better view of the filename in the tree, particularly under Windows, and the pattern is now in a specific column.

Development

• the video feature is now also requiring MediaPipe - https://mediapipe.dev/#!
• workspaces: extended max length of the attribute key. It was 12, it’s 20 now.
• features.ini and object detection: can support all versions of opencv-contrib. They changed the output of the detection data structure at version 4.5.4.
• imgdata: the object's detection can load all models then enable or disable any of them.
• Sights and SightsWriter migrated into "imgdata" package.
• sppas.command is cd to $SPPAS to make 'sppas.command' working properly with the Finder on macOS and is creating a symlinks virtual environment on macOS because it does not support the copies option
• setup.bat: search for python.exe first.

SPPAS-4.3

(2022, 22th March)

Known problems

This version has an import bug: it does not start at all on some computers.

Resources

• Updated French acoustic model, added French pronunciation dictionary for standard French with name fre.dict, and updated documentation of French resources.

Annotations

• MediaPipe (https://mediapipe.dev/) can be used by Face Detection and is used by default in the Face Landmarks automatic detection. It is installed to enable the video feature.
• Face landmarks: smooth sights trajectory
• Search for IPUs: the default output pattern is -ipus
• RMS: can optionally add two tiers with min and max value of each interval
• CuedSpeech: a new tier is created with the coordinates of the vowels (if sights are given)
• If any, add properly the language in the metadata of the output transcription file, and add the linguistic resource filename in the metadata of the tier.

Development

• anndata: bug correction when reading and writing .lab files
• plugins: audioseg bug correction when searching for the annotated file and a new option is added.
• plugins: classphones bug correction in imports and new options.
• GUI-Edit: the player control can play frame-by-frame with a step value, not only 1.
• facesights & faceidenity: smooth points trajectory with another algorithm
• cuedspeech: what, when and where files separated in 3 packages

GUI

• updated icon: a more modern version with fewer colors
• updated splash image to add a representation of both a video and a hand
• plugins: solved a problem of page refresh under Windows when adding or deleting a plugin

Scripts

• formants.py creates a file with f1, f2, f3, f4 of all phonemes. It requires Praat and to install the pypi of ParselMouth.
• saplay.py plays an audio file or a part of it. It uses either pyaudio or simpleaudio. At least one of them must be installed with pypi.
• img_to_cartoon.py is able to cartoonize an image or a video.
• sppasseg.py performs the full automatic segmentation process. It’s a three automatic steps process:
  1. Prepare the data (if required):
     • Nothing is done if the ortho. transcription is already time-aligned into the IPUs;
     • Fill in IPUs if the ortho transcription is already available but not time-aligned. Notice that it can’t work if the recording protocol was not very very very strict: it works only if the number of sounding segments EXACTLY matches the given number of transcribed segments.
     • Search for IPUs and auto transcribe with the STT DeepSpeech. It requires installing DeepSpeech in the currently used Python and giving the path of the models. Get it here (DeepSpeech + English model): https://github.com/mozilla/DeepSpeech/releases/ or here for another language: https://discourse.mozilla.org/t/links-to-pretrained-models/62688
  2. Perform Speech Segmentation:
     • no option to configure the annotations. They are all fixed internally!
     • can estimate an intensity coefficient;
     • can predict silent pauses (the ones into the IPUs).
  3. Format the output (if asked):
     • can map the phoneme into another set (IPA, Praat, …) if a mapping table is given. It’s a file with two columns, both separated by a whitespace: 1st is SPPAS phoneme, 2nd is expected phoneme.
     • can create a data structure with all the results and write into a JSON file.

SPPAS-4.4

(2022, 5th April)

Known problems

The use of Python 3.6 or 3.7 is possible but Python 3.8 is recommended because: - the feature audioplay can’t be enabled with a more recent version, - recent versions of MediaPipe have better results and the most recent one is available for python 3.8.

Annotations

• Hand&Pose: a new automatic annotation of an image or a video. SPPAS is a wrapper for MediaPipe Hand detection and Mediapipe Pose detection. It also proposes a custom solution to detect right-left hands of a person.

SPPAS-4.5

(2022, 15th April)

Known problems

For a full experience of SPPAS using of Python 3.8 or 3.9 is recommended. The use of Python 3.6 or 3.7 is possible.

Install

• Under Windows, pipwin is installed and used when pip failed to install a package. pipwin installs unofficial python package binaries for Windows provided by Christoph Gohlke here: http://www.lfd.uci.edu/~gohlke/pythonlibs/
• Both simpleaudio and PyAudio are installed, if available for the OS. The audioplay feature is enabled if one of them is successfully installed.

Package

• a demo is added with all its annotated files. Only the orthographic transcription was performed manually. SPPAS did the rest.

Resources

• updated French dictionary (fra.dict)

GUI

• Page Edit: select the nearest annotation when clicking in a hole of a tier
• Page Analyze: when a tier is copied/paste, its media and controlled vocab are also copied/paste to the destination file.

Annotations

• Alignment: add the aligner name in the metadata of the result, i.e., either julius, hvite or basic.
• FaceSights: bug correction when writing coordinates in a CSV file.

SPPAS-4.6

(2022, 22th August)

Known problems or bugs

The French resources distributed in the package are corrupted. They have to be re-installed to perform Alignment annotation.

For a full experience of SPPAS using of Python 3.8 is recommended because some dependencies are no longer maintained and no new release is published. Other versions of Python are possible but without any warranty.

Annotations

• CuedSpeech is continued. The Proof of Concept is turned into some stable and tested packages, but it is not yet version 1.
• FaceIdentity: new option to shift the portrait/selfie at the left or right
• FaceIdentity and FaceSights: debug of the smoothing. The points are no longer shivering.
• HandPose: bug correction when writing hand sights for an image for XRA format
• Updated demo files with the results of the automatic annotations

Plugins

• The plugins folder migrated from the base directory to the sppas directory; and each plugin is now a python package.
• audioseg: A version 3.0 is released, an option video was added to segment both the audio and the video into tracks. Track filenames start with an index instead of the interval number.

Resources

• updated French dictionary (fre.dict) with new entries added and with J instead of n j in all words containing gn

Development:

• anndata.tier: bug correction in index() method to search for the index of a point in a point-tier.
• preinstall: a new key pip_opt in the features.ini file. The installer is now trying pip with option –pre if the installation of the stable version failed. The pip_opt allows assigning options to pip. It is used by wxPython to fix the pre-build host.
• imgdata.coordinates: added a xy ratio in parameters of portrait() to force a ratio between width and height. Default is 14:16.
• anndata.label: can optionally add the same tag into a label, without adding their scores
• anndata.aio.praat: an appropriate error message in case of chronological textgrid file.

SPPAS-4.7

(2022, 12th October)

Annotations

• CuedSpeech is continued. The transition duration of the shape is reduced (d2 is before), and the hand picture is not blur on the video when the position is changing.
• Text Normalization: a new option is used by default to estimate the number of tokens in each IPU, but only if the token is speech, events are ignored (i.e., dummy, noise, laugh, pause and silence).

Development

• Python 3.10 compatibility.
• Bug correction with imports if video is not enabled.
• Bugs correction in workspaces: Can append a file with a whitespace before the pattern, like toto - Copie.txt and the relative path should work properly.
• Installation: bug correction with quotes when launching a command that solved the installation problem - setup.bat does not need to be launch twice anymore, once is enough!
• Installation: do not stop an installation if a pip package fails to be updated.
• Script

  mlf2labs.py

  : a new script to split an MLF file into several lab files.
• The custom event’s management changed in the Phoenix UI.

GUI

• There’s no longer a LogWindow in the installation wizard.
• Bug correction in slider and progress dialog (mainly used by the Edit page).
• Revised toolbars.
• Page Files: two buttons moved from associate to files (remove missing, add bros) and the 'delete' button migrated from files to associate.
• Page Editor: Search dialog debugged.

Resources

• Updated list of phones for Bengali language, updated dictionary and acoustic model

SPPAS-4.8

(2022, 14th December)

Development

• Break the dependency to wx when importing annotations. The SPPAS API can then be used without requiring wx to be installed.
• the script evalsegmentation.py is more generic (vowel and consonants lists), boxplots are in case-insensitive order, can deal with phonemes with a ’' and do not remove R files.
• anndata.aio: bug correction when reading CSV. Now, use the Python CSV reader.
• Updated SWHIG

Annotations

• Alignment: bug correction when using HVite instead of Julius.
• The transcribed tier – with orthographic transliteration, can’t have a name with ipu anymore.

Resources

• Added an acoustic model of Persian language for Alignment
• A new acoustic model for English, with phonemes of British English added, and the full model re-trained.
• Updated French vocabulary and pronunciation dictionary

Installation

• Under Windows, do not stop an installation if pipwin fails to be installed or updated.
• Under macOS: Homebrew is removed of the automatic setup. Users will have to install it themselves.

SPPAS-4.9

(2023, 10th February)

Web site url has changed: http://sppas.org/. An automatic redirection is maintained.

Development

• new ui package: htmlmaker is a package to work with a tree of HTML nodes and to serialize it into an HTML page.
• updated SWHIG, and files README, AUTHORS and LICENSE of src folder
• a standard codemeta.json is added at the root of the src folder. It replaces the sppas.json file that was previously localed in etc folder.
• anndata: bug correction, when reading and writing a CSV (a problem with quotes was solved).
• all available features are saved into the .app~ file, with true or false value to mention that they are enabled or not.
• preinstall: catch the exception http.client.HTTPResponse which can occur if unstable internet connection when downloading an annotation (because too large zip file).

Resources

• updated English resources, the resources’ documentation indicates the list of phonemes, including the ones of British English.
• updated French resources

GUI

• a major bug correction: when the workspace is modified in a page, the other ones are properly informed and taking into account the new version.
• Page Edit: a major bug correction allowing to play audio with pyaudio under windows.

SPPAS-4.10

(2023, 10th March)

Web site url has changed: https://sppas.org/. An automatic redirection is maintained.

Major change: The Setup is launching a SPPAS Web-based application, instead of the one based on WxPython.

GUI

• The Setup program has been fully re-implemented with a Web-based User Interface. As a consequence, it does not require wxPython to be installed. Notice that it must be launched within the SPPAS python virtual environment. Firefox is highly recommended, none of the other web-browsers was tested.

Development

• new ui package swapp for SPPAS Web-based APPlication. Already contains a httpd package to implement a server and a handler, and an app_setup package for the SPPAS Setup, with a main program, main settings, etc.
• ui.phoenix was renamed to ui.wxapp – which means WX-based sppas application, to be consistent with ui.swapp.
• Migrated sppas/bin/preinstallgui.py into ui.wxapp package. It is intended to be removed in next version, like the WX-based setup app.
• The custom settings of user interfaces are stored in wxapp and swapp folders instead of sppas base directory.
• preinstall: The installer system was entirely revised. An alternative list of pip packages can be defined, the progress indicates absolute percentage, and the installation error is not raised anymore if the package was installed but returned a warning/error message.

Annotations

• The diagnosis of the file is made on the exact filename without lowering the extension like it was previously done, because the file extensions for the annotations are case-sensitive.

SPPAS-4.11

(2023, 10th June)

Python 2.7.9+ compatibility is restored for most of the annotations.

New SPPAS logo

Resources

• Updated cueConfig-fra for better management of the neutral position and shape

Annotations

• TextNormalization can deal with the HTML tag cut like <cut unit="ms" from="12" to="34"/> into the orthographic transcription. See the transcription convention documentation for details.
• TextNormalization, Phonetization and Alignment annotations can be performed on a raw text. When using the CLI, they can use stdin and stdout.
• CuedSpeech can produce the key from stdin, either from time-aligned phonemes or directly from a phonetization (without variants)
• CuedSpeech Video Tagging is fully re-implemented, and tested. New options are available to apply filters on the tagged hands.
• CuedSpeech: add an output annotated file with coordinates, only if createvideo option is enabled and log level is 0 (debug mode).
• Implemented a SpeechSeg annotation which allows to perform TextNormalization, Phonetization, Alignment and RMS, all-in-one.
• Implemented an AutoTrs annotation which allows to prepare the data automatically.
• The script sppasseg.py is now using AutoTrs and SpeechSeg instead of implementing them.

Development

• modified the way to instantiate the global settings. The main consequence is that there’s no longer a bunch of warning messages on macOS due to the miss of locale.
• bin.plugin.py: added a –list argument to print the list of installed plugins
• debug of the plugin audioseg: corrected the SPPAS path search when no SPPAS environment variable is defined, and modified python into python3 into the JSON file – for macOS only
• debug of table file formats: do not write arff and xrff in bytes anymore
• debug of TextNormalization annotation which can now deal properly with capitalized characters
• debug of Alignment annotation when PhonAlign is a PointTier
• debug of reading a RAW transcription
• debug of FaceSights: added an empty list of sights when an annotation is not labeled (no estimated sights)
• debug of the slope_intercept estimation: the function does not return (0,0) anymore in case slope is 0.
• debug of the translation system which is invoked only once when starting the application, and not each time a message has to be translated
• imgdata: created the sppasImageFilter() class to apply filters on an image
• annotations.CuedSpeech: the Proof-of-Concept of the When part of the annotation is turned into a cleaned and tested package.
• annotations.CuedSpeech: the Proof-of-Concept of the Where part of the annotation has been fully changed to predict the position of five hand sights.

GUI

• Setup: separated the existing video feature into two different ones: video and mediapipe. This is because mediapipe is supported only by python 3.6 to 3.10. This change allows annotations using video to continue to work even without mediapipe.
• The setup application is not blinking anymore neither when processing nor when clicking a button. Its design slightly changed to make it hopefully nicer. A button to increase the contrast is added. The accessibility is verified and compliant with WCAG2.1.
• Page Editor: added an extended frame player which can play videos and display the previous, current, next frames and information of the played video file(s).

SPPAS-4.12

(2023, 14th July)

Resources

• added an utf-8 specific - in punctuation list
• updated French list of words
• Updated orthographic transcription convention, mainly for the $ support which is now used to surround any segment that will be buzzed.

Annotations

• enabled audio files in the list of possible output extensions for the annotations
• New automatic annotation for Anonymization of audio and video files. Allows selecting a pattern in a tier in order to buzz the intervals in the annotated file. The annotation can blur the detected faces of a video during these intervals or only the mouth. Anonymization of audio intervals is preserving the intensity, but not the F0.
• CuedSpeech: a better estimation of the angle for the hand. Bug correction of the "key 7" target finger.
• Text Normalization: corrected bugs of cut tag introduction. Do not try to find cut tags in tier of type Point. Modified and extended the use of the cut tag. It generates a dummy tagged interval, or the content of the event attribute value. See oriana1.txt as example. Allowed the support of $ character in the orthographic transcription.
• FaceDetection: modified the default models.

GUI

• New SPPAS logo
• Page Editor: updated the extended frame player. It can display a ruler and the currently selected tier for the period of the three frames.
• Page Editor: Added an icon to switch between information and frame view for videos in the timeline.

Development

• started a prototype of web UI for cued speech video tagging
• added classes to manage the dynamic pages of the SPPAS web site
• script sppasseg.py: corrected an inconsistency between file names and added a –json option. Modified the way to estimate the normalized RMS values.
• bin plugin.py: corrected support of -o when mode is apply

SPPAS-4.13

(2023, 25th August)

Known bug & others

SPPAS is using a library with name "cv2" to display images. This library has a critical bug that may cause the SPPAS Graphical User Interface to crash. It happens when it is asked to cv2 to display two images at the same time. SPPAS is waiting a few delays between two frames, but it may not be enough if the OS is not properly managing events. It (obviously) occurs mainly on Windows.

This version is partially compatible with Python 2.7.x, and compatibility is guaranteed until Python 3.11.

GUI

• Do not quit when answering "no" in the dialog, and changed some colors.
• Close properly files before exit. In interactive mode, ask for confirmation when a file was modified.
• Page Editor: annotating videos. The video windows can show the videos in a single frame as usual, and they also can show a sequence of three frames, by playing forward or backward in a "frame-by-frame" way. A number of frames to skip can be defined. The window with the three frames of the video also displays a ruler to indicate the position in time of the frames and the currently selected tier. Buttons allow moving the selected boundary of its annotation(s). The play button and the frame-by-frame buttons are synchronous.
• Page Editor: two new buttons for zooming up or down the elements of the timeline.
• Page Editor: added tooltips on most of the buttons, and keyboard shortcuts
• Page Editor: debugged the search dialog, and added a "Hide" button
• Page Editor: removed restriction to create a new annotation outside its visible part and allowed use of the Escape key to cancel an annotation creation
• Page Editor: debugged the current time position information. Now it is updated properly when scrolling and when clicking on the stop button.
• Page Editor: modified some icons hopefully for better understanding
• Page Editor: added the possibility to scroll and zoom in the time ruler of the timeline, by dragging with the mouse: Scroll by dragging with no key pressed, and Zoom with CTRL key pressed (CMD on macOS). It allows defining very precisely the displayed period.

Annotations

• Text Normalization: allowed + and * in special pronunciations, like for example: [word, wo+rd]
• Alignment: yet another solution to rescue token's alignment when tokenization is not matching phonetization. More messages are also displayed both in the report and in the logs.
• FaceSights: corrected a bug when writing coordinates in a CSV file, improved robustness when input face detection/ident was of poor quality.
• HandPose: increased robustness by catching exception when scaling coordinates too much.
• CuedSpeech: modified the radius estimation of the predicted intervals, do not predict anymore a position transition from side to side, updated default vowel positions, bug correction when estimating time interval (the degenerated interval is forbidden).

Development

• anndata.tier: modified the solution to find annotations for a more robust one, added a parameter "radius_overlaps"

Resources

• French: modified "fre" pronunciation dictionary

SPPAS-4.14

(2023, 24th October)

The main purpose of this version was to update the installer.

Development

• Removed dependency to the python distutils library which is removed of Python 12 (PEP 632)
• Migrated htmlmaker, httpd and website packages into a new WhakerPy external standalone application: https://whakerpy.sf.net
• Added a 'base' feature which is pre-installed in the setup.command/setup.bat files, before launching the web UI. It's installing WhakerPy and Clamming, a package for creating documentation.
• Added a 'dist' folder into sppas and force pip to get wheels in 'dist' first then download if not found.
• Another solution to fix the system installer is implemented. The previous solution based on the use of "uname()" was unstable.
• Migrated 'get_lang_list()' from settings to 'po', and removed the DEFAULT_LOCALE from the settings.
• Added pyproject.toml into sppas folder to describe the project and eventually build a wheel file with "python -m build"
• videoplayer: removed the frame size limitation that resized images to at max width=512px, except for Linux. Bug correction too to provide an infinite loop which was making the UI unresponsive.
• Removed user documentation source files.
• Updated the setup.bat. It is now more robust if several versions of Python are installed.

SPPAS-4.15

(2023, 24th December)

The main purpose of this version was the "CuedSpeech" automatic annotation.

Development

• Upgraded dependency to WhakerPy, from version 0.2 to 0.3.1.
• Package "config": code cleaning, tests added, refactoring and PEP-402 compliance.
• Annotated files: do not systematically set the "file_path" metadata. It allows fixing it to an empty value and sharing the file without indicating the full path (with author name, etc...).
• script evalsegmentation.py: added the argument -s to fix the delta step value (default is 0.005).
• calculus: The UBPA scoring class prints (nb success occurrences / nb values) in the final result.
• User interface: Removed the 'website' package => migrated into WhakerPy 0.3.
• CuedSpeech.whenhand: fully verified package with code cleaned and re-organized, comments added, tests added, etc.

Annotations

• CuedSpeech.whatkey: Added a generated tier for the phoneme structures. This generated CS-PhonStructs tier does not contain the neutral information, and renamed the tier CS-PhonClass into CS-KeysClass.
• CuedSpeech.whenhand: Added a predictor model based on (Duchnowski et al., 2000).
• CuedSpeech.whenhand: Modified predictor model based on (Attina, 2005) for the code to really match this reference.
• CuedSpeech.whenhand: Completed our custom Rules-Based Model.

Others

• Contact: develop@sppas.org is no longer a valid e-mail. Use contact@sppas.org instead.
• Added support for dnf/Fedora of the automatic installer.

SPPAS-4.16

(2024, 20th January)

This is mainly a debug version: it solves a problem with the UI. Previous versions were displaying the message numbers instead of the messages themselves.

Development

• bug correction when defining the list of requested languages. English language was added into the list in a wrong way, so none of the requested languages was matching an available language in 'po' folder. There won't be message numbers anymore instead of the messages themselves.
• Updated both Clamming and WhakerPy requirements.
• Modified the SPPAS header in all files to provide Python12 message "SyntaxWarning: invalid escape sequence '\ '"
• Fixed Python12 messages "SyntaxWarning: invalid escape sequence ...", mainly in "Text Normalization" annotation.
• Refactoring of files and classes in annotations: log is becoming report, sppasLog is sppasReport, and SppasFiles is sppasFiles.
• In Text Normalization "num2text": added 'fre' for French

SPPAS-4.17

(2024, 29th January)

Annotations

• In CuedSpeech, the "When" code is stable. It's v1 of the custom model, which become the default model.

SPPAS-4.18

(2024, 13th March)

The package audiodata is no longer a part of SPPAS. It is now available as a standalone library, living its own life. It is included in the "base" feature of SPPAS and is automatically installed during setup. For your own usage, you can get it here

Development

• Removed all dependencies to audioop Python standard library because it will be removed in Python 3.13, - with no proposed alternative solution. AudiooPy is used instead.
• Migrated 'config' and 'preinstall' packages from 'sppas.src' to 'sppas' due to ModuleNotFoundError when launching preinstall.py. This is a consequence of replacing the local audiodata by the AudiooPy dependency.
• Removed opencv-python-headless of the required pip dependencies of "video" feature: it allows FaceRecognition to work properly, which is used by the "Person Face Identity" annotation.
• src.videodata: debugged the object detection with a video buffer. The system was raising an exception, - and stopping the annotation, when an invalid image is read in the video. The image is now replaced by a blank one.
• src.videodata: debugged the "next" function of the videobuffer. The buffer was not flushed, so, if the last buffer was not full, it was still containing the images of the previous one.
• src.videodata: corrected bug when writing a video with a tag.
• Code cleaning and verified in scripts: facedetection.py, faceidentity.py, facesights.py.
• HandPose annotation: corrected a bug when hand image size is 0.

GUI

• sppas.ui.swapp: fully reconsidered the 'main.css' to look like the incoming 'wexa.css'.
• sppas.ui.swapp.statics: added an accessible font which is used in contrast mode.

Known bugs

The automatic annotation "Fill In IPUs" stops and there's the following message in the report: ... [ ERROR ] Unknown format code 'd' for object of type 'float'

Quick Fix:

Edit the file \sppas\src\annotations\FillIPUs\sppasfillipus.py and change line 209 by:

         m1 = _info(1290).format(int(filler.get_vol_threshold()))
     

A second problem comes from the re-sampling, in AudiooPy-0.2, so that SPPAS-4.18 can't perform "Alignment" on audio files of 48kHz.

SPPAS-4.19

(2024, 29th March)

Development

• Identified bugs of SPPAS-4.18 are corrected.
• The Setup uses a new package "whakerexa" in the GUI, from https://whakerexa.sf.net.

Annotations

• CuedSpeech is installed by default.
• Face Landmark is installed by default.

Known bugs

The automatic annotation "Search for IPUs" stops and there's the following message in the report: ... [ ERROR ] Unknown format code 'd' for object of type 'float'

Quick Fix:

Edit the file \sppas\src\annotations\SearchIPUs\silences.py and change line 275 by:

         threshold = int(volumes[int(median_index)])
     

SPPAS-4.20

(2024, 13th May)

The main change is about the terms of the license: the source code was previously under the terms of the GNU General Public License v3.

From this version, the source code of SPPAS is under the terms of the GNU Affero General Public License, version 3. Read it here

Development

• Identified bug of SPPAS-4.19 in "Search for IPUs" feature is corrected.
• Updated dependencies for 'base' feature, and for the UI:
  • "WhakerPy == 0.6",
  • "AudiooPy == 0.3",
  • "ClammingPy >= 1.7"
  • "Whakerexa" == 0.4
• plugins: corrected a bug when executing a python plugin. The plugin must use the version of python in the virtual environment.
• Added bin.makedoc.py to generate automatically the API documentation into an "api" folder. Requires Whakerexa to be installed, and a custom statics/clamming.css file.

Annotations

• CuedSpeech: added "W" as an authorized vowel category in the file with rules.
• HandPose: cast image array data from dtype('float32') to dtype('uint8'), to provide a Mediapipe TypeError on some images.
• HandPose: a more robust solution for hand detection. It makes use of a rescue detector if no hand is detected with the regular one.
• CLI usage: added '-W' argument to all annotation scripts, to give a workspace filename.

Resources

• Cued Speech: added 6 series of hands.
• added face detection models

Known bugs

Language resources can't be downloaded, so this version can only work with French/English languages because they are already available in the package.

SPPAS-4.21

Development

• Identified bug of SPPAS-4.20 in language download is corrected.
• Object detection removes the alpha channel, if any.
• 'sppas' package can be imported even if 'audioopy' is not installed and 'base' feature is False.

Annotations

• FaceDetection: can detect faces on an image, including those with an alpha channel.
• FaceSights: can also annotate an image — not only a video, with one or several faces

GUI

• Updated the app for the cued speech video tagger.

Latest

SPPAS-4.22

The copyright is modified in headers to properly add the right holder 'CNRS'.

Development
