SpkIdEvalStream

After you have trained a set of speaker templates, use the SpkIdEvalStream task to identify any sections of an audio stream where the trained speakers are present.

NOTE:

To process an audio file, use the SpkIdEvalWav task.

Parameters

ClosedSet Whether the task that you are running is a closed-set test.  
DiagFile The name of the file to write diagnostic information to.  
DiagLevel The level of detail to include in the diagnostic information.  
DiscardShort Exclude segments shorter than a specific duration from further analysis.  
MinNonSpeech The minimum size in seconds of non-speech segments.

Sfreq The sample frequency of the audio stream to process.  

TemplateExt

The file extension to use for template files.  
TemplateList A list file that lists multiple speaker template files to use. Yes, if TemplateSet is not specified

Example

http://localhost:15000/action=AddTask&Type=SpkIdEvalStream&File=C:\Data\Speech.wav&TemplateSet=speakers.ats&ClosedSet=False&Out=results.ctm

This action uses port 15000 to instruct HPE IDOL Speech Server, which is located on the local machine, to search the audio stream for speakers based on the template set file speakers.ats, and to write the identification results to the results.ctm file. Because the test is set to be open-set, HPE IDOL Speech Server marks sections where no speaker scores above their respective thresholds as Unknown_.
