IvSpkIdDevelFinal

After you gather score statistics for each of the speaker templates, you can calculate the iVector score threshold based on one or more development files, and generate a new set of iVectors with the thresholds.

You can specify multiple template development files in a list file, or just a single development file.

Example

http://localhost:15000/action=AddTask&Type=SpkIdDevelFinal&DevFile=speakers.ivd&TemplateList=ListManager/speakers&Bias=0.2

This action uses port 15000 to instruct HPE IDOL Speech Server, which is located on the local machine, to use the development scores in speakers.ivd to calculate thresholds (using a Bias value of 0.2 when balancing recall against precision) for each speaker template specified in the speakers list. HPE IDOL Speech Server updates the template files in place to contain the threshold values calculated.
