LangIdBndWav

The LangIdBndWav task reads in data from an audio file, converts it into language identification features, and determines boundaries where the language changes. It returns the language identification results between boundaries.

Parameters

Parameter Description Required
Type The task name. Set to LangIdBndWav. Yes
Beam The beam width of the search process.  
ClassList A list of language classifiers to use. Yes
ClassPath The path to the directory containing the language classifiers. Yes
DnnFile The Deep Neural Network acoustic modeling file to use.  
File The audio file to process. Yes
Lang The name of the language pack to use. Yes
LangList A subset of languages to use from the classifier list file.  
NBest The maximum number of language candidates to include in the output file.  
Out The file to write language identification results to. Yes
OutB The file to write boundary point information to. Yes
SegSize The maximum results segment size.  
SegSmoothWin The size of the smoothing window.  
SegStep The step size in phones of the analysis window.  
SugdInputChannels The channel layout of the input media file.  
SugdInputFrequency The sampling rate of the input media file.  

Example

http://localhost:13000/action=AddTask&Type=LangIdBndWav&File=C:\Data\Speech.wav&ClassList=ListManager/OptClassSet&ClassPath=C:\LangID\&Out=SpeechLang1.ctm&OutB=SpeechBnd.ctm

This action uses port 13000 to instruct Speech Server, which is located on the local machine, to identify languages and language boundaries in the Speech.wav file using the language classifiers specified in the OptClassSet list. The action instructs IDOL Speech Server to write the identification results to the SpeechLang1.ctm file and the boundary information to the SpeechBnd.ctm file.
