abstract = {In this position paper we present a methodology to automatically annotate
French text for Cued Speech (CS), a communication system developed for people
with hearing loss to complement speech reading at the phonetic level. This visual
communication mode uses handshapes in different placements near the face in
combination with the mouth movements (called ‘cues’ or ‘keys’) to make the phonemes
of spoken language look different from each other. CS is used to acquire skills in
lip-reading, in oral communication and for reading. Despite many studies demonstrating
its benefits, there are few resources available for learning and practicing it,
especially in French. We thus propose a methodology to phonemize written corpora so
that each word is aligned with the corresponding CS key(s). This methodology is proposed
as part of a wider project aimed at creating an augmented reality system displaying a
virtual coding hand where the user will be able to choose a text upon its complexity
for cueing. }

abstract={In this position paper, we argue for a role for overt phonetizers
in second language learning. Phonetization or letter-to-sound
conversion is often used simply as a module of text-to-speech
synthesis (TTS) or to create pronunciations for dictionaries.
Based on evidence of the overwhelming influence of
orthographic input on second language pronunciation and word
learning, we argue that on their own (or coupled with TTS),
phonetizers can be effective support tools for two broad groups:
1. language learners and instructors, and 2. non-specialized
users. We address the issues involved and give the example of
a multilingual phonetizer under development in New
Caledonia, a special status collectivity of France in the South
Pacific. Encountering words and names in one of the almost 30
languages of the indigenous Kanak people of New Caledonia is
an everyday experience, for example, on class lists, road signs
and in news articles. Pronouncing these words is often a
challenge, since each of the languages has its own phonology
and its own orthography. We discuss the motivation behind the
phonetizer, challenges in its development, and potential
applications, many of which are common to other endangered
or vulnerable and under-resourced languages.}

To adequately segment QF, features like diphthongization of long vowels and

phenomena. Dictionaries and lexicons must also be adapted and integrate differences
in lexical units and in the phonology of QF. This paper presents the development

American corpus (ref) in order to conduct a cross-cultural comparison of
participants’ smiling behavior in humorous and non-humorous sequences in American
English and French conversations. In this article, the methodology used to
collect and enrich the corpus is presented: experimental protocol, technical
choices, transcription, semi-automatic annotations, manual annotations of
smiling and humor. An exploratory study investigating the links between smile
and humor is then proposed. Based on the analysis of two interactions, two
questions are asked: (1) Does smile frame humor? (2) Does smile has an impact
on its success or failure? If the experimental design of Cheese! has been
elaborated to study specifically smiles and humor in conversations, the high
quality of the dataset obtained, and the methodology used are also replicable
and can be applied to analyze many other conversational activities and other
multimodal modalities.},

Nous avons comparé trois langues (polonais, français et anglais américain)

Des positions articulatoires ont été calculées sur la base des fréquences
des phonèmes dans chacune des trois langues dans des corpus de parole
spontanée. Etonnamment, les résultats tendent à montrer que les positions
articulatoires majoritaires sont très similaires dans les trois langues.
Il semble ainsi que l’usage de la parole spontanée, et donc la
distribution des phonèmes dans les langues, gomme les disparités des
systèmes phonologiques pour tendre vers une mobilisation articulatoire
commune. Des investigations plus approfondies devront vérifier cette
observation. },

on speaker-hearer smiling behavior in humorous and non-humorous conversations

computer-mediated interactions between English native speakers, and the
French one consists of four face-to-face interactions between French native
speakers. The goal of the study is twofold: first, we analyze the link between
smiling and humor, focusing on the degree of synchronicity of smiling and
the intensity of smiling during humorous and non-humorous segments; second,
we investigate the various targets mobilized in conversational humor.
The results obtained comparing the two data-sets show a correlation between
the presence of humor, an increased smiling intensity, and an increase in
the synchronized smiling behaviors displayed by participants. However, the
two corpora also differ in terms of the displayed smiling behaviors: French
participants display more non-synchronic smiling when humor is absent and
more synchronic smiling when humor is present. Regarding the various targets
of humor (Speaker, Recipient, Other person, Situation, Speaker+Recipient),
while their distribution is different – it is more evenly distributed in the
French data – the way in which these are mobilized in order to become humorous
is quite similar.},

abstract = {Most of the time, analyzing the phonetic entities of speech requires the
alignment of the speech recording with its phonetic transcription. However, studies
on automatic segmentation have predominantly been carried out on read speech or on
prepared speech while spontaneous speech refers to a more informal activity, without
any preparation. As a consequence, in spontaneous speech numerous phenomena occur
such as hesitations, repetitions, feedback, backchannels, non-standard elisions,
reduction phenomena, truncated words, and more generally, non-standard pronunciations.
Events like laughter, noises and filled pauses are also very frequent in spontaneous
speech. This paper aims to compare read speech and spontaneous speech in order to
evaluate the impact of speech style on a speech segmentation task. This paper
describes the solution implemented into the SPPAS software tool to automatically
perform speech segmentation of read and spontaneous speech. This solution consists
mainly in two sorts of things: supporting an Enriched Orthographic Transcription
for an optimization of the grapheme-to-phoneme conversion and allowing the
forced-alignment of the following events: filled pauses, laughter and noises.
Actually, these events represent less than 1 % of the tokens in read speech and
about 6 % in spontaneous speech. They occur in a maximum of 3 % of the Inter-Pausal
Units of a read speech corpus and from 20 % up to 36 % of the Inter-Pausal Units
in the spontaneous speech corpora. The UBPA measure – Unit Boundary Positioning
Accuracy, of the proposed forced-alignment system is 96.09 % accurate as regards
read speech and 96.48 % for spontaneous speech with a delta range of 40 ms.},

Linguistics annotation, especially when dealing with multiple domains, makes use of
different tools within a given project. More and more annotated corpora are now available,

linguistic phenomena, annotation tools lead to a variety of models, theories and formalisms.
This diversity results in heterogeneous description formats, each tool developing its own
framework. Then, none of the annotation tools are directly interoperable, each one using
a native format, some of them on top of XML, some others developing an ad hoc markup
language. The mapping between user formats is then an important issue. This paper presents
an efficient annotation representation framework and the related tool to convert from/to
some of the existing annotation file formats of various annotation software tools for

Then, the corpus has been manually transcribed and automatically aligned. The
alignment has been corrected by an expert phonetician. Moreover, the corpus
benefits from an automatic syllabification and an Automatic Detection of Acoustic
Phone-Based Anomalies. Finally, in order to interpret phonetic variations due to
pathologies, a perceptual evaluation of each patient has been conducted.

software tool designed for the needs of automatically producing annotations of speech
at the level of utterance, word, syllable and phoneme based on the recorded speech
sound and its orthographic transcription. In other words, it can automatize
the phonetic transcription task for speech materials, as well as the alignment task
of transcription with speech recordings for further acoustic analyses.
Special attention will be given to the methodology implemented in SPPAS, based
on algorithms which are as language-and-task-independent as possible. This
procedure allows for the addition of new languages quickly and for the adaptation of
this tool to the user's specific needs. Consequently, the quality of the automatic
annotations is largely influenced by external resources, and the users can modify the
process as needed. In that sense, phoneticians need automatic tools and these tools can
be significantly improved by phonetician input. },

abstract = {The question of interoperability for linguistic annotated resources covers
different aspects. First, it requires a representation framework making it
possible to compare, and eventually merge, different annotation schema. In
this paper, a general description level representing the multimodal linguistic
annotations is proposed. It focuses on time representation and on the data
content representation: This paper reconsiders and enhances the current and
generalized representation of annotations. An XML schema of such annotations
is proposed. A Python API is also proposed. This framework is implemented in
a multi-platform software and distributed under the terms of the GNU Public License.}

other-repetitions on 8 dialogues of CID - Corpus of Interactional Data.
Evaluations performed on one speaker are good with a F1-measure of 0.85.
Retrieved OR occurrences are then statistically described: number of words,
distance, etc.}

material, the protocol and some basic quantitative features of the existing
corpus are presented. The corpus was collected under two communicative
conditions, one audio-only condition and one face-to-face condition. The
recordings took place in a studio and a sound attenuated booth respectively,
with head-set microphones (and in the face-to-face condition with two video
cameras). The recordings have been segmented into Inter-Pausal-Units and
transcribed using transcription conventions containing actual productions and
canonical forms of what was said. It is made publicly available online.}

abstract = {The interaction between Members of Parliament (MPs) is convention-based
and rule-regulated. As instantiations of individual and group confrontations,
parliamentary debates display well-regulated competing discursive processes.
Unauthorised interruptions are spontaneous verbal reactions of MPs
who interrupt the current speaker.
This paper focuses on the answers of the current speaker to these disruptions.
It introduces an annotation scheme for a political debate dataset which is
mainly in the form of video annotations and audio annotations.
The annotations contain information ranging from general linguistic to
domain specific information. Some is annotated with automatic tools, and
some is manually annotated. One of the goals is to use the information
to predict the categories of the answers by the speaker to the disruptions.
A typology of such answers is proposed and an automatic categorization
system based on a multimodal parametrization is successfully performed.}

abstract = {This paper presents the benefit of using multiple lexical units in the
post-processing stage of an ASR system. Since the use of sub-word units can reduce
the high out-of-vocabulary rate and improve the lack of text resources in statistical
language modeling, we propose several methods to decompose, normalize and combine
word and sub-word lattices generated from different ASR systems. By using a sub-word
information table, every word in a lattice can be decomposed into sub-word units.
These decomposed lattices can be combined into a common lattice in order to generate
a confusion network. This lattices combination scheme results in an absolute syllable
error rate reduction of about 1.4% over the sentence MAP baseline method for a
Vietnamese ASR task. By comparing with the N-best lists combination and voting method,
the proposed method works better.}

continuous speech recognition (LVCSR) system for Khmer, the official language of Cambodia,
spoken by more than 15 million people. As an under-resourced language, develop a LVCSR
system for Khmer is a challenging task. We describe our methodologies for quick language
data collection and processing for language modeling and acoustic modeling. For language
modeling, we investigate the use of word and sub-word as basic modeling unit in order to
see the potential of sub-word units in the case of unsegmented language like Khmer.
Grapheme-based acoustic modeling is used to quickly build our Khmer language acoustic model.
Furthermore, the approaches and tools used for the development of our system are documented
and made publicly available on the web. We hope this will contribute to accelerate the
development of LVCSR system for a new language, especially for under-resource languages
of developing countries where resources and expertise are limited.}

This method can also be used for the statistical language model (SLM) adaptation.
An information retrieval system is used after the first pass of the ASR
system to obtain a set of relevant documents. These documents are then used
to generate the new vocabulary and/or corpus. In this paper, we propose a new
retrieving method well-adapted for this purpose. Experiments were carried out
on French with a 28% OOV rate reduction. Experiments were also carried out
on English for the SLM adaptation, with 7.9% perplexity reduction, and
minor WER improvement.}

Several segmentation criteria are proposed using topic shift detection or just blindly comparing the con-

Experiments with a large corpus of articles from the French newspaper Le Monde show tangible
advantages when different models are combined with a suitable strategy.
Experimental results show that different strategies for topic shift detection have to be used depending
on whether high recall or high precision are sought. Furthermore, methods based on topic independent
distributions provide complementary candidates with respect to the use of topic-dependent distributions
leading to an increase in recall with a minor loss in precision.}

expansion terms. Such scores are used to select and weight expansion terms
within Rocchio's framework for query reweigthing. We compare ranking with
information-theoretic query expansion versus ranking with other query expansion
techniques, showing that the former achieves better retrieval effectiveness on
several performance measures. We also discuss the effect on retrieval effectiveness
of the main parameters involved in automatic query expansion, such as data sparseness,
query difficulty, number of selected documents, and number of selected terms,
pointing out interesting relationships.}

The model follows a multi-expert decision paradigm based on fuzzy relations in
which fuzzy variables express degrees of reliability of expert decision.
Heterogeneous measures are integrated by the fuzzy relations whose structure
and components may evolve in time.
Experiments resulted in more than 80% topic classification accuracy on articles
of the French newspaper Le Monde which describe a very large variety of facts
with a very large vocabulary (of the order of 500,000 words).
Experiments show a significant improvement when the above mentioned integration
of multi-expert decision is used. A robust strategy for dynamic Language Model
(LM) selection, based on topic recognition and switching between topic models,
is proposed. It is effective because it relies on a small set of well trained
topic-dependent LMs and on reliable topic recognition. By using perplexity as
a performance measure of the LM switching model, a tangible reduction is
observed with respect to the use of a single, general, static LM.}
