Online Speech to Text

The VoxSigma SaaS offers three main processing functions : the identification of the language spoken in an audio document, the conversion of recorded speech input to text, and the synchronization of a transcription with the speech signal (also called speech-text alignment). It handles content in many European languages as well as Mandarin and Arabic.
