Corpus and annotation

Corpus annotation “can be defined as the practice of adding interpretative, linguistic information to an electronic corpus of spoken and/or written language data. ‘Annotation’ can also refer to the end-product of this process” (Leech, 1997).

Annotation software

Before using any automatic annotation tool/software, it is important to consider its error rate (where applicable) and to estimate how those errors will affect the purpose for the annotated corpora.

SPPAS is an awarded Research Software

Data preparation for automatic annotations

(Step 1) Recording Speech

Recording audio

Recording audio: software tools

audacity
sox

Recording speech: SPPAS requirements

(Step 2) Inter-Pausal Units

IPUs = sounding segments

Orthographic transcription into the IPUs

(Step 3) Transcribing Speech

Orthographic transcription:

Orthographic transcription: SPPAS convention

Transcription example 1 (Conversational speech)

donc + i- i(l) prend la è- recette et tout bon i(l) vé- i(l) dit bon [okay, k]

Transcription example 2 (Conversational speech)

ah mais justement c’était pour vous vendre bla bla bla bl(a) le mec i(l) te l’a emboucané + en plus i(l) lu(i) a [acheté,acheuté] le truc et le mec il est parti j(e) dis putain le mec i(l) voulait

euh les apiculteurs + et notamment b- on ne sait pas très bien + quelle est la cause de mortalité des abeilles m(ais) enfin il y a quand même + euh peut-êt(r)e des attaques systémiques
