Vocapia Research announces the availability of beta versions of two new
functionalities to its VoxSigma automatic speech-to-text transcription service,
both providing dynamic vocabulary and language model adaptation. The first new
functionality is an on-the-fly document based adaptation and the second, carries
out adaptation to the news on a daily basis.
Automatic on-the-fly adaptation allows the user to provide texts related to the
audio document being processed, what can be considered topic/domain adaptation.
These accompanying texts serve to increase the lexical coverage of the
speech-to-text system and to adapt the language model to the specific domain of
the audio document with the aim of improving the transcription accuracy.
Daily adaptation based on current news events helps ensure that transcription
system vocabulary stays up-to-date, thereby providing better coverage of hot
news items. This daily update improves the transcription accuracy on popular
topics, particularly on named entities, that is person, company/organization and
place names, that have peaky popularity in news data.

recognition, and speaker identification to transform raw audio and
audiovisual data into structured and searchable XML documents. This
technology relies on over 25 years of research at LIMSI-CNRS, with
which there is a priviledged partnership. Joint systems developed
with LIMSI have achieved top ranks in national and international
challenges of speech-to-text transcription. The most common
