# SpkIdDevelStream

DEPRECATED:

The `SpkIdDevelStream` task is deprecated in IDOL Speech Server version 11.4 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 `SpkIdDevelStream` task takes a single audio stream, along with the name of the speaker the stream 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`).

NOTE:

To process audio from a file, use the SpkIdDevelWav task.
