VoxSigma^® Speech to Text Software Suite

The VoxSigma software suite for Linux offers large vocabulary speech-to-text capabilities in multiple languages. It includes adaptive features allowing the transcription of noisy speech, such as speech over background music. The software suite has been designed for professional users needing to transcribe large quantities of audio and video documents such as broadcast data, either in real-time or in batch mode. Versions can also be used to transcribe call-center data.

The full speech-to-text conversion process (also call voice-to-text conversion) is done in three steps. The software first identifies the audio segments containing speech, then it identifies the language being spoken if it is not known a priori, and finally it converts the speech segments to text. It includes adaptive features allowing the transcription of noisy speech such as speech with background music.

The speech-to-text processing result is a fully annotated XML document including labels for speech and non-speech segments, speaker labels, words with time codes and high quality confidence scores. This XML file can be directly indexed by a search engine, or alternatively can be converted into plain text with capitalization and punctuation.
