The LangIdCumWav
task reads in data from an audio file and converts it into language identification features. It returns the running language identification score at periodic intervals. This is the score for all the data from the start to the current point.
Parameter | Description | Required |
---|---|---|
Type | The task type. Set to LangIdCumWav . |
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 |
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). | |
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=LangIdCumWav&File=C:\Data\Speech.wav&ClassList=ListManager/OptClassSet&ClassPath=C:\LangID\&Out=SpeechLang4.ctm
This action uses port 13000
to instruct Speech Server, which is located on the local machine, to identify the language 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 SpeechLang4.ctm
file.
