Open Source

VOSK is an innovative, next generation open source speech recognition toolkit. It focuses on life-long semi-supervised learning with huge datasets. The idea is to apply audio fingerprinting approach to learn speech sounds as well as other non-speech sounds. We are also considering support for distributed multiparty learning as core feature of the toolkit.

VOSK enables fully offline speech recognition without internet connection and data transfer.

To name few other advantages or our approach: we can quickly train on 100000 hours of speech data, we can correct recognizer behavior just by adding samples. We can also parallelize training across thousands of nodes.

Check Vosk documentation and try it.
