About the Technology

Voci’s speech-to-text technology breaks speech out into words, language, dialect, emotion, and speaker. Voci uses a speaker-independent, large vocabulary continuous speech recognizer (LVCSR) to perform speech recognition. The LVCSR comprises two parts: an acoustic model that focuses on how things sound and a language model that focuses on words and word sequences.

Voci’s most evolved language models are currently for North American English, UK English, and Australian English. It is also available for North American and European Spanish, with more languages on the way.
