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.
| 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. | |
| ClassPath | The path to the directory containing the language classifiers. | |
| 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. | |
| 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. | |
| SilThresh | The threshold between what the task identifies as silence and non-silence. | |
| SpeechThresh | The threshold between speech and non-speech (music or noise). | |
| SugdInputChannels | The channel layout of the input media file. | |
| SugdInputFrequency | The sampling rate of the input media file. |
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=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.
