IvSpkIdEvalStream

After you have trained a set of speaker templates, use the IvSpkIdEvalStream task to run iVector-based identification of any sections of an audio stream where the trained speakers are present.

NOTE:

To process an audio file, use the IvSpkIdEvalWav task.

Parameters

Parameter Description Required
Type The task name. Set to IvSpkIdEvalStream. Yes
AllowEmpty Whether to produce gender labels as output if no speakers are specified.  
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.  
FrameDupl The balance between performance and speed for audio preprocessing DNN classification.  
Out The file to write the results to.  
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.  
TemplatePath The path to the directory containing the speaker templates.  
TemplateSet An audio template set file.  
ThreshScale The rate at which to scale the thresholds.  

Example

http://localhost:15000/action=AddTask&Type=IvSpkIdEvalStream&File=C:\Data\Speech.wav&TemplateSet=speakers.ivs&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 iVector-based template set file speakers.ivs, and to write the identification results to the results.ctm file.
