Speechmatics is a speech AI partner for native.builder. Their APIs turn audio into accurate text (and text back into speech) so you can add transcription, voice agents, captions, and speaker-aware features without building speech infrastructure yourself.

​
What Speechmatics is

Speechmatics provides enterprise-grade speech-to-text and text-to-speech APIs built for real-world audio:
  • Real-time and batch — Stream live audio over a WebSocket, or submit pre-recorded files for full transcripts
  • Multilingual — Transcription across 56+ languages, with strong accent and dialect handling
  • Speaker diarization — Label who said what in multi-speaker conversations
  • Flexible deployment — Cloud, on-prem, or on-device when data residency matters
Typical Builder builds: meeting notes apps, call centers, accessibility captions, voice agents, and any product that needs reliable speech in the loop.

​
Build with Speechmatics in Builder

You don’t need a special Speechmatics mode in Builder. Describe the voice or transcription feature you want, and ask the Builder agent to use Speechmatics. Examples you can paste into chat:
  • “Add live transcription with Speechmatics for uploaded meeting recordings”
  • “Build a voice agent that uses Speechmatics for speech-to-text and text-to-speech”
  • “Use Speechmatics diarization so each speaker gets their own transcript section”
Provide your Speechmatics API key when the agent asks (or store it as a secret in your connected backend). Builder wires the API calls, UI, and flow from your prompt.
Be explicit: say “use Speechmatics” in the brief so the agent picks that partner instead of a generic speech library.
