# SpkIdDevelWav

The `SpkIdDevelWav` task takes a single audio file, along with the name of the speaker the file is associated with, and generates score statistics for one or more speaker templates. These statistics are then stored in an audio template development file (`.atd`).

You can use one or more development files when estimating the threshold for each speaker template. If for any audio segment the top-scoring template falls below the threshold associated with that speaker, the segment is assumed to be an unknown speaker.

For more information on development score files, see the IDOL Speech Server Administration Guide.

## Example

`http://localhost:15000/action=AddTask&Type=SpkIdDevelWav&File=C:/Data/BrownSpeech4.wav&Label=Brown&TemplateList=ListManager/speakers&DevFile=speakers.atd`

This action uses port 15000 to instruct IDOL Speech Server, which is located on the local machine, to generate match statistics for the speaker named `Brown` by checking the example speech in `BrownSpeech4.wav` against the speaker templates specified in the speakers list, and writing the results to the `speakers.atd` development file.

To process streamed audio, use the StreamSidOptimize task.
