Gladia
Speech-to-text API for live and recorded audio, multilingual with code-switching
Linked from gladia.io · checked 29 Oct
- Tool type
- Speech-to-text API
- Made for
- Developers and voice product teams
- Runs on
- Gladia-hosted API (EU and US hosting options)
- Accessed via REST, WebSocket, and SDKs; the API console is for setup, not an end-user app.
What it does
Gladia takes in live audio streams or recorded audio files, such as meeting recordings, call center calls, podcasts, and video, and returns transcripts. Output includes text with timestamps and, optionally, speaker labels, translation, sentiment, named entities, PII redaction, and summaries. Real-time mode returns text as people speak, while async mode processes whole files and suits accuracy-focused, richer output.
Developers typically call the REST or WebSocket API, or use the official Python and JavaScript SDKs, to add transcription to meeting assistants, contact center tooling, voice agents, and media workflows. The product offers code-switching across 100+ languages with Solaria-1 and integrations with voice platforms such as Pipecat, LiveKit, Vapi, and Twilio. Webhooks deliver async results without polling.
Gladia suits teams building voice products or analyzing conversations who need multilingual transcription, and regulated buyers, since the pricing page lists GDPR, HIPAA, and SOC 2 Type 2. Self-serve use is prepaid credits billed per audio hour, with 50€ in free credits for new accounts. Limitations: Solaria-3 covers 6 languages versus 100+ on Solaria-1, and self-serve is opted into model training by default, with opt-out available.
