WavToPlh

DEPRECATED:

The WavToPlh task is deprecated in IDOL Speech Server version 11.5 and later. Micro Focus recommends that you use the newer Deep Neural Network (DNN) techniques, rather than GMM-based acoustic models.

This task is still available for existing implementations, but it might be incompatible with new functionality. The task might be deleted in future.

The WavToPlh task creates an audio feature (.plh) file from an audio file. The AmTrain task uses audio feature files when adapting acoustic models.

Parameters

Parameter Description Required
Type The task name. Set to WavToPlh. Yes
File The audio file to process. Yes
NormFile The acoustic normalization file (.ian file in the language pack) to use. Yes
Out The feature file to create. Yes
Sfreq The sample frequency of the audio file to process. Only if the frequency of the audio file is not 16,000 Hz
SugdInputChannels The channel layout of the input media file.  
SugdInputFrequency The sampling rate of the input media file.  

Example

http://localhost:15000/action=AddTask&Type=WavToPlh&File=C:\myData\Speech.wav&NormFile=C:\SPKID\SPKID16k.ian&Out=Speech1.plh

This action produces the Speech1.plh file from the Speech.wav audio file, using the SPKID16.ian normalization file.
