The LangIdBndLif
task reads in language identification features from file and determines boundaries in the feature sequence where the language changes. It 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. | |
File | The language identification feature (.lif) file to process. | Yes |
LangList | A subset of languages to use from the classifier list file. | |
MinPhoneRate | 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.
http://localhost:13000/action=AddTask&Type=LangIdBndLif&File=C:\Data\Speech.lif&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.lif
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.
