Audio intelligence
Use audio summarization to turn every call, meeting, and recording into a ready-to-read recap. Add one parameter to your transcription request and get a general, concise, or bullet-point transcription summary back with the transcript, live or async, with no prompt to write. Hosted in the EU or US, with your data staying in the region you choose.
Test the audio summarization on your own calls and meetings. No expiry, no credit card.
33.9% WER on Switchboard, the highest speech-to-text accuracy of 6 providers tested.
Summarize audio in any supported language, including calls where speakers switch mid-sentence.
Start every summary from a transcript you can trust. Gladia leads on the audio that summaries come from: real customer calls, unscripted conversations, and multi-speaker recordings where a meeting recap needs to know who said what.
Drop the separate LLM call and the prompt maintenance. Summarization runs in the same request as transcription and returns an AI meeting summary with the transcript, with nothing to pass between services.
Upload a file, pass a URL, or open a real-time WebSocket session.
Set "summarization": true and choose general, concise, or bullet_points. Skip the type to get a general summary.
The summary arrives with the transcript in the async response. For live sessions, it's sent by callback once the stream closes.
Choose a ready-made recap with no setup, or run your own prompts for custom outputs with Audio-to-LLM. Both can run in the same request.
