Vapi

Use Soniox Speech-to-Text as the transcriber for Vapi voice AI agents to get low-latency, multilingual, real-time transcription on phone and web calls.

Overview

Vapi is a developer platform for building, testing, and deploying voice AI agents. A Vapi assistant handles phone and web calls by combining a speech-to-text transcriber, a large language model, and a text-to-speech voice, while Vapi manages telephony, turn-taking, and call orchestration.

Soniox is available as a built-in transcriber provider in Vapi, giving assistants low-latency, multilingual real-time speech recognition with automatic language detection and mid-conversation language switching.
