Speech-to-text API with sub-300ms real-time latency, 100+ languages, code-switching and built-in audio intelligence for voice products.
Gladia is a French speech-to-text API built for product teams, transcribing audio in 100+ languages with real-time latency under 300 milliseconds. Its Solaria model family delivers word error rates competitive with the best US engines, with code-switching support for conversations that jump between languages mid-sentence, a real condition in European markets.
Beyond raw transcription, the API enriches audio into structured data: speaker diarization, sentiment analysis and entity recognition ship built in. Native integrations with LiveKit, Pipecat, Twilio and Retell make it a drop-in speech layer for voice agents, meeting assistants and call platforms, in batch or streaming mode.
Key benefits:
- Real-time transcription with latency under 300ms for live voice products
- 100+ languages with code-switching for multilingual conversations
- Audio intelligence including diarization, sentiment and entity recognition
