Transcription API: turn audio and video into text

Workflows and apps can now turn recordings into text with a built-in transcription service: meeting recordings, voicemails, interviews, podcast episodes, or any audio or video file. Like every built-in service, it needs no account of your own and bills to your workspace.

How it works

• Start a job. Send a link to the audio, or upload the file itself (audio or video, up to 1 GB), and you get back a job ID.
• Get the transcript. Check the job for its status, full text, detected language, and audio length, plus speaker turns when speaker labels are on and word-level timings when you ask for them.
• Better accuracy on your vocabulary. Pass key terms, such as product names or industry jargon, to bias recognition: up to 1,000 on the most accurate model and 200 on the other.
• Two models. Choose between two AssemblyAI models, with the provider kept behind a seam so more can be added.
• Fair billing. The price is locked when a job starts, each job is billed once, and a failed job is free.

Use it from code workflows, app handlers, and sandbox scripts, and pair it with the decision service to route calls by what was said.
