IvSpkIdDevelStream

The IvSpkIdDevelStream task takes a single audio stream, along with the name of the speaker the stream is associated with, and generates 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).

NOTE:

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

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