About Speechmatics
What is Speechmatics?
Speechmatics is a speech-to-text API that converts spoken language into text in real time. It supports 55+ languages and dialects, covering over half the world's population. It also offers text-to-speech and voice agent capabilities.
Problem it solves
For businesses needing accurate, low-latency transcription at scale, especially for multilingual and multi-speaker scenarios. It addresses privacy concerns by offering on-device, on-prem, and cloud deployments with no data logging as standard.
Who it is for
Ideal for developers, SaaS companies, contact centers, media companies, and legal or healthcare organizations requiring secure, global voice AI. Not suited for hobbyists or tiny projects needing only occasional transcription without commitment—though there is a free tier.
