LangIdBndLif

DEPRECATED:

The LangIdBndLif task is deprecated in IDOL Speech Server version 11.5 and later. Identifying language on feature files is no longer supported. Use the LangId task to identify languages in a file or stream instead.

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

The LangIdBndLif task reads in language identification features from file and determines boundaries in the feature sequence where the language changes. The task returns the language identification results between boundaries.

Parameters

Parameter Description Required
Type The task type. Set to LangIDBndLif. Yes
Beam The beam width of the search process.  
ClassList A list of language classifiers to use.  
ClassPath The path to the directory containing the language classifiers.  
ClosedSet Whether to use closed set or open set language identification.  
DiagFile The file to write the diagnostic information to.  
DiagLevel The level of detail to include in the diagnostic information.  
File The language identification feature (.lif) file to process. Yes
LangList A subset of languages to use from the classifier list file.  
MinRate The minimum phone rate (phones per second).  
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.  
NOTE:

The ClassList parameter is required only if you want to change the audio sample rate, or if you want to use your own custom classifiers. You might also need to specify the ClassPath parameter, depending on the location of the classifier files.

Example

http://localhost:15000/action=AddTask&Type=LangIdBndLif&File=C:\Data\Speech.lif&ClassList=ListManager/OptClassSet&ClassPath=C:\LangID\&Out=SpeechLang1.ctm&OutB=SpeechBnd.ctm

This action identifiese languages and language boundaries in the Speech.lif file using the language classifiers specified in the OptClassSet list. IDOL Speech Server writes the identification results to the SpeechLang1.ctm file and the boundary information to the SpeechBnd.ctm file.
