Soniox
What is Soniox?
Soniox is a multilingual voice AI platform providing speech-to-text, text-to-speech, and speech translation APIs. Its unified models support real-time and asynchronous audio processing across more than 60 languages, including multilingual and code-switching conversations. Developers can use REST and WebSocket APIs, official SDKs, speaker diarization, contextual customization, and streaming translation to build voice agents, captions, analytics, and accessibility tools. Soniox targets product teams, developers, contact centers, healthcare platforms, media companies, and other organizations working with spoken audio. The platform differentiates itself through real-time multilingual processing, broad language-pair coverage, and a single API layer for transcription, translation, and speech generation.
How to use Soniox?
Create a Soniox account, open the Console, and generate an API key; choose the appropriate REST or WebSocket endpoint and configure a speech-to-text, translation, or text-to-speech request; stream audio or submit a file, then use the returned transcript, translation, speaker data, or generated audio in your application.
