Overview
Speechmatics is a British company founded in 2006 that builds speech recognition designed to work across accents and dialects. It trains largely with self-supervised learning on unlabelled audio, which improved accuracy for speakers that mainstream systems transcribe poorly. Its engine is licensed by broadcasters, contact centres and software vendors and runs in the cloud or on-premise.
