# IvSpkIdDevelWav

DEPRECATED:

The `IvSpkIdDevelWav` task is deprecated in IDOL Speech Server version 11.5 and later. Use the IvSpkIdDevelAudio 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.

The `IvSpkIdDevelWav` task processes a single audio file to generate scores for tuning iVector thresholds. The task generates a single iVector development score file (`.ivd`). You can append the scores to an existing `.ivd` file.

You can score the audio against one or more iVector template files (`.iv`).

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

## Example

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

This action generates 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 writes the results to the `speakers.ivd` development file.

To process streamed audio, use the IvSpkIdDevelStream task.
