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.
