The LangIdFeature
task converts an audio file containing a single language into a language identification feature (.lif) file. Language identification feature files are required for training language classifiers.
Parameter | Description | Required |
---|---|---|
Type | The task type. Set to LangIdFeature . |
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. | |
AudioUpsampling | Whether to allow audio upsampling if the input audio has a sample rate too low for the task. | |
Beam | The beam width of the search process. | |
DnnFile | The Deep Neural Network acoustic modeling file to use. | |
EndTime | The end of an audio section to process. | |
File | The audio file to process. | Yes, if InputType is File . |
InputType | The type of audio to process (file, binary data, or stream). | |
Lang | The name of the language pack to use. | Yes |
Out | The language identification feature (.lif) file to create. | Yes |
SilThresh | The threshold between what the task identifies as silence and non-silence. | |
SpeechThresh | The threshold between speech and non-speech (music or noise). | |
StartTime | The beginning of an audio section to process. | |
SugdInputChannels | The channel layout of the input media file. This parameter does not apply when InputType is Stream . |
|
SugdInputFrequency | The sampling rate of the input media file. This parameter does not apply when InputType is Stream . |
