Speechmatics
Speech APIs powering Voice AI
Speechmatics provides speech-to-text APIs for real-time and pre-recorded audio transcription, text-to-speech, and translation across 55+ languages, supporting voice agents, captioning, meeting notes, and contact center analytics. The platform addresses the need for low-latency, multilingual, multi-speaker transcription across diverse audio conditions, including accented speech and background noise.
Key capabilities include speaker diarization, custom vocabulary, word timings, and partial transcription, with models selectable by use case for accuracy, multilingual performance, or latency. Deployment options span cloud, on-premises, and on-device. Integrations and SDKs cover Python, JavaScript, and .NET, with native integrations for voice agent frameworks. A Medical Model supports clinical transcription, and the Linden model is designed for voice agents. Security certifications include ISO 27001, GDPR, HIPAA, and SOC 2 Type II.
Speechmatics is aimed at developers and enterprises building products such as live captioning, voice agents, meeting platforms, contact center analytics, and legal or medical transcription. Packaging includes a free tier with starter credit and no card required, a usage-based Pro tier for batch and real-time transcription, and an Enterprise tier with custom pricing, flexible deployment options, and enterprise support.
