SpeechSilClassification

The SpeechSilClassification task segments an audio file or stream by content, classifying each segment as either speech, non-speech, or music.

Parameters

Parameter	Description	Required
Type	The task name. Set to `SpeechSilClassification`.	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.
DoDialTones	Whether to include dial tones in addition to DTMF tones, if tone detection is enabled.
DoToneClass	Whether to perform DTMF and dial tone identification.
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).
MaxSegSize	The maximum audio class size in frames.
MinSegSize	The minimum segment size in frames.
Out	The file to write the results to.	Yes
Sfreq	The sample frequency of the audio file to process.
SilThresh	The threshold between what the task identifies as silence and non-silence.
SpeechBias	Whether to bias towards speech (rather than music, noise, or silence) in the identification of audio segments.
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`.
