LangIdSegStream

DEPRECATED:

The LangIdSegStream task is deprecated in IDOL Speech Server version 11.5 and later. Use the LangId task 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 LangIdSegStream task receives audio data as a binary stream, converts it into language identification features, and then processes the data in fixed-sized chunks. The task returns the language identification results for each chunk.

Parameters

Parameter Description Required
Type The task type. Set to LangIdSegStream. Yes
AppDnnBase The location of the appResources directory, which contains the DNN and .ian files to use.  
AppFrameDupl The balance between performance and speed for audio preprocessing DNN classification.  
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.  
DnnFile The Deep Neural Network acoustic modeling file to use.  
FrameDupl An integer value which allows for greater time efficiency with only a minimal loss of recognition accuracy.  
Lang The name of the language pack to use. 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
SegSize The maximum results segment size.  
SilThresh The threshold between what the task identifies as silence and non-silence.  
SpeechThresh The threshold between speech and non-speech (music or noise).  
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=LangIdSegStream&ClassList=ListManager/OptClassSet&ClassPath=C:\LangID\&Out=SpeechLang6.ctm

This action identifies languages in the audio stream using the language classifiers specified in the OptClassSet list, and writes the identification results to the SpeechLang6.ctm file.
