# NullUnknownSpeakerAudioData

Removes (deletes) an audio sample that represents an unknown speaker, but does not remove the training generated from the audio data.

After running this action speakers can still be recognized but the audio cannot be retrieved from the database and cannot be used to retrain Media Server. If future versions of Media Server feature enhancements to speaker identification that require retraining, you will need to supply the audio again.

Type: synchronous

Parameter | Description | Required
--- | --- | ---
`database` | The name of the database that contains the unknown speaker data. | Yes
`audiolabels` | A comma-separated list of labels that specifies the audio samples to remove. If you do not set this parameter, Media Server removes all of the samples that represent unknown speakers. | No
