# SpkIdDevelFinal

DEPRECATED:

The `SpkIdDevelFinal` task is deprecated in IDOL Speech Server version 11.4 and later. Use the IvSpkIdDevelFinal task instead.

This task is still available for existing implementations, but it might be incompatible with new functionality. The task might be deleted in future.

After you gather score statistics for each of the speaker templates, you can calculate the threshold associated with each speaker. You can do this for each speaker template individually, or across the whole set at once.

You can specify multiple template development files in a list file, or just a single development file.

## Parameters

Parameter | Description | Required
--- | --- | ---
Type | The task name. Set to `SpkIdDevelFinal`. | Yes
Bias | The balance bias to use between reducing false hits and reducing rejections. |
DevExt | The file extension to use for input audio template development files. |
DevFile | The name of the audio template development file. | Yes, if you are using a single file
DevList | A list file that specifies multiple development files to use. | Yes, if `DevFile` is not set
DevPath | The path to the directory containing the audio template development files. |
DiagFile | The file to write the diagnostic information to. |
DiagLevel | The level of detail to include in the diagnostic information. |
OutExt | The file extension to use for updated speaker template files. |
OutPath | The directory to write updated speaker template files to. |
OutTemplate | The file name to use for a single updated speaker template file. |
Sfreq | The sample frequency of the audio file to process. |
TemplateExt | The file extension to use for template files. |
TemplateFile | A single speaker template file to use to generate scores. | Yes, if `TemplateList` is not set
TemplateList | A list file that lists the speaker template files to use to generate scores. | Yes, if `TemplateFile` is not set
TemplateName | The name associated with the template file. | Yes, if `TemplateFile` is set
TemplatePath | The path to the directory that contains the template files. | Yes, if `TemplateList` is set and the templates are not in the default location (the `SpeakerIDDir` directory)

## Example

    http://localhost:15000/action=AddTask&Type=SpkIdDevelFinal&DevFile=speakers.atd&TemplateList=ListManager/speakers&Bias=0.2

This action uses the development scores in `speakers.atd` to calculate thresholds (using a `Bias` value of `0.2` when balancing recall against precision) for each speaker template specified in the speakers list. IDOL Speech Server updates the template files in place to contain the threshold values calculated.
