Request body

urlstring

URL of the audio file to be processed

webhookstring

Webhook URL to receive results when job is completed (optional)

webhookStatusOnlyboolean

When true, webhook payload only includes jobId and status (excludes output). Useful for large payloads.

model'precision-2' | 'precision-3' nullable

Diarization model to use

numSpeakersnumber

Number of speakers. Only use if the number of speakers is known in advance. Number of speakers is detected automatically if not provided. Setting this value results in better overall diarization performance. In rare cases where we cannot honor this request (e.g. short files and large number of speakers), a warning will be added to the output. Equivalent to sending minSpeakers==maxSpeakers

minSpeakersnumber

Minimum number of speakers (must be <= maxSpeakers if both are set)

maxSpeakersnumber

Maximum number of speakers (must be >= minSpeakers if both are set)

vadSensitivitynumber

Controls the sensitivity of voice activity detection (VAD). Float in [-5.0, 5.0], defaults to 0.0 (balanced precision/recall). Higher values increase recall (less speech missed). Lower values increase precision (less non-speech detected as speech). Only available for the precision-3 model.

crosstalkSensitivitynumber

Controls the sensitivity of overlapping speech (cross-talk) detection. Float in [-5.0, 5.0], defaults to 0.0 (balanced precision/recall). Higher values increase recall (detect more overlapping speech). Lower values increase precision (detect only clear overlaps). Only available for the precision-3 model.

turnLevelConfidenceboolean

Includes turn-level confidence values in the output.

speechProbabilityboolean

Includes a frame-level speech probability curve in the output, in the speechProbability key. Only available for the precision-3 model.

crosstalkProbabilityboolean

Includes a frame-level overlapping speech (cross-talk) probability curve in the output, in the crosstalkProbability key. Only available for the precision-3 model.

speakerProbabilityboolean

Includes per-speaker, frame-level probability scores in the output, in the speakerProbability key. Only available for the precision-3 model.

exclusiveboolean

Includes exclusive diarization values in the output in exclusiveDiarization key (equivalent to diarization but without overlapping speech).

confidenceboolean

Include confidence values in the output. Output is considerably larger when this option is enabled. Output includes a list of confidence scores with a resolution. Not supported by the precision-3 model, which returns an error if this is set; use speechProbability, crosstalkProbability or speakerProbability instead.
