About

Speechmatics is the Cambridge-based speech recognition company whose accuracy on diverse accents, dialects, and noisy audio is the reason most enterprise ASR RFPs shortlist them. The platform covers batch transcription, real-time streaming, translation, speaker diarisation, and the Flow voice AI API that handles conversational turn-taking for voice agents. Supports 50+ languages with a single self-service API, on-prem deployment for regulated workloads, and EU-hosted infrastructure for GDPR-sensitive customers. Pricing is usage-based with a generous free tier and published per-hour rates that undercut US-hosted competitors for European traffic.
