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.

This action writes scores for all templates generated by using the Brown.atv feature file (which contains features based on speech for Brown) into a development file called Brown.ivd.
