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.
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. |
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.

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.
