# IvSpkIdTrain

The `IvSpkIdTrain` task uses the set of feature files that you created by using the IvSpkIdFeaturetask to train a new iVector speaker template.

If you are using multiple feature files, you must create a list file that contains a list of all the feature files. You can do this manually, or by using the List Manager.

Each element of the list should be the file name relative to the Speaker ID directory, and must include the file extension. For example:

    BrownSpeech1.ivp
    BrownSpeech2.ivp
    BrownSpeech3.ivp

NOTE:

If the files are not stored in the Speaker ID directory, you can use the DataPath parameter to specify the location.

For more information about HPE IDOL Speech Server's list manager, see the HPE IDOL Speech Server Administration Guide.
