Soniox

Speech-to-text API providing accurate audio transcription with speaker diarization and language detection. Best for workflows that convert spoken audio to text — meeting transcription, voice command processing, and audio content indexing. Unlike ElevenLabs (text-to-speech), Soniox handles the inverse: converting speech audio into structured text. 6 endpoints available through Lava’s AI Gateway. See the Soniox API docs for full documentation.

Supports both managed (Lava’s API keys) and unmanaged (bring your own credentials) mode.
