What we know about Speechmatics

This is our verified profile of Speechmatics, a speech-to-text apis platform - accuracy-first enterprise STT with flexible deployment (SaaS, container, on-prem). Every fact about Speechmatics below carries the source it came from and the day we checked it.

Speechmatics does not publish a public per-minute rate we have been able to verify, so the price figure here stays blank until we can confirm one. We would rather show nothing than a guessed number; if you have a current Speechmatics quote, it is the fastest way for us to close that gap.

On capabilities, Speechmatics covers language auto-detection, word-level timestamps, custom vocabulary / keyterm boosting, entity detection, sentiment analysis, and summarization endpoint. Each of those is verified against Speechmatics's own docs or dashboard, not marketing copy.

For compliance, with Speechmatics: SOC 2 Type II is in place. If you are in a regulated space, confirm the current posture with Speechmatics before you commit, since these change plan by plan.
