# IvSpkIdEvalWav

DEPRECATED:

The `IvSpkIdEvalWav` task is deprecated in IDOL Speech Server version 11.5 and later. Use the IvSpkId 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 `IvSpkIdEvalWav` task performs iVector-based speaker identification on a single audio file.

NOTE:

To process an audio stream, use the IvSpkIdEvalStream task.
