ai/transcribe-audio — Convert audio files to text using speech-to-text AI.

Where it appears

The Transcribe Audio block lives in the AI group of the Workflow Builder.

Field	Type	Required	Default	Description
`audioFile`	text (multi-line, supports references)	Yes	—	Audio file to transcribe. Supports MP3, WAV, M4A, FLAC, OGG, WebM (max 25 MB).
`language`	text	No	—	ISO-639-1 language code (e.g., en, es, fr). Leave empty for auto-detection.

Inputs are the configurable fields above. The block produces these outputs:

Outputs

Reference an output downstream with <Transcribe Audio.field>.

Name	Type	Description
`success`	boolean	Whether transcription succeeded
`text`	string	Transcribed text
`language`	string	Detected language code
`duration`	number	Audio duration in seconds
`segments`	json	Array of segments with text and timestamps
`error`	string	Error message if failed

A minimal configuration for this block:

{
  "type": "ai/transcribe-audio",
  "config": {
    "audioFile": "<PreviousStep.field>"
  }
}

Required field (audioFile) must be set, or the block fails validation before it runs.
On failure the error output is populated; downstream blocks that reference other outputs may not receive values.
