IvSpkIdDevel

The IvSpkIdDevel task processes one or more speaker ID feature files (generated by the IvSpkIdFeaturetask) to generate scores for tuning iVector-based score thresholds.

You can use one or more input files, against one or more model files. You can use this task either to generate a single iVector development score file (.ivd), or to append the information to an existing .ivd file.

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