About Speechmatics
Speechmatics builds speech-to-text APIs designed for real conversations rather than clean recordings. Its stated focus is understanding varied accents, multiple speakers and multilingual speech, with low latency so that voice agents and live captioning can respond in real time.
The product line includes Speech to Text, Voice Agents and Text to Speech, with an interactive demo where visitors can speak or pick sample audio. The homepage introduces Linden, a model purpose-built for voice agents. Case studies describe uses in live captioning, agent frameworks, media monitoring and on-device transcription in video editing software, where recognition runs locally instead of in the cloud.
Speechmatics is a commercial provider with developer documentation, enterprise and security pages, and a pricing page. Developers can get started for free, and larger organizations can contact sales. On-device and enterprise deployment options are available in addition to the hosted API.
