Calculates the threshold that is necessary to distinguish between a specified speaker and an unknown speaker.
NOTE: You only need to run this action if the audio you want to process contains unknown speakers.
Before running this action:
training=true. Then train the speaker with the action BuildSpeaker, or train all speakers with the action BuildAllSpeakers.training=false).For more information about training speaker identification, refer to the Media Server Administration Guide.
Type: synchronous
| Parameter | Description | Required |
|---|---|---|
bias
|
The bias to use when calculating the threshold, as a number from 0 to 1. The default value is 0.3 and this is suitable in most cases. Using a higher value increases the calculated threshold, which can result in fewer false positives. Using a lower value decreases the threshold, which can result in fewer missed results (better recall). |
No |
database
|
The name of the database that contains the speaker. | Yes |
identifier
|
The identifier of the speaker to calculate the threshold for. | Yes |
/action=EstimateSpeakerThreshold&database=news&identifier=newsreader
This action is asynchronous, so Media Server always returns success accompanied by a token. You can use this token with the QueueInfo action to retrieve the status of the action:
