What is Speechmatics?
Speechmatics is a speech technology company that offers speech-to-text and text-to-speech APIs. Its speech-to-text models transcribe audio in real time or from pre-recorded files, and are designed to handle accented speech, background noise, several speakers at once and speakers who switch languages mid-sentence. The site lists over 55 languages, speaker diarization, custom vocabulary and a medical model for clinical terms.
Developers connect to the service through an API, with integrations for voice agent frameworks, and can choose where data is processed (EU, US or Australia) or deploy on cloud, containers, or on-device depending on privacy needs. Users can also try a live transcription demo in the browser. Optional add-ons include translation, summaries, topics, sentiment and PII redaction.
