# SetSpeakerThreshold

Manually sets the threshold that is necessary to distinguish between a specified speaker and an unknown speaker. You can use this action to optimize the threshold for a speaker, to reduce the number of false positives or missed results.

Type: synchronous

Parameter | Description | Required
--- | --- | ---
`database` | The name of the database that contains the speaker. | Yes
`identifier` | The identifier of the speaker to set the threshold for. | Yes
`threshold` | The threshold to use. A higher threshold can result in fewer false positives. A lower threshold can result in fewer missed results (better recall). | Yes

## Example

    /action=SetSpeakerThreshold&database=news&identifier=newsreader&threshold=32

## Response

    <autnresponse>

To automatically calculate thresholds for your speakers, use the action EstimateAllSpeakerThresholds.

NOTE: Using the action EstimateAllSpeakerThresholds or EstimateSpeakerThreshold will overwrite any threshold that you have set manually.
