Transcribers (Speech-to-text)

Look up the speech-to-text providers Vapi supports and their compliance coverage.

This page lists the speech-to-text (STT) providers Vapi supports, with each provider’s ID and compliance coverage.

The transcriber converts the caller’s speech to text for your voice agent. You select one by setting transcriber.provider and transcriber.model on an assistant. See Create Assistant in the API reference.
