The ClusterSpeechTel task clusters telephony speech into speaker segments. For example, if two speaker clusters are identified, the output labels are Cluster_0 and Cluster_1 respectively.
| Parameter | Description | Required |
|---|---|---|
| Type | The task name. Set to ClusterSpeechTel. |
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. | |
| EndTime | The end of an audio section to process. | |
| File | The input audio file. | Yes, if InputType is File. |
| FixTime | A fixed size for speaker clusters. | |
| InputType | The type of audio to process (file, binary data, or stream). | |
| Lang | The name of a language pack. | Yes |
| MaxNumSpeakers | The final maximum number of speakers to produce. | |
| MergeThresh | The threshold below which to merge clusters. | |
| MinNumSpeakers | The final minimum number of speakers to produce. | |
| Out | The file to write the results to. | |
| 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. |
http://localhost:15000/action=AddTask&Type=ClusterSpeechTel&File=1h.wav&Lang=ENUK-tel&Out=outTel
This action clusters the data in the 1h.wav telephony audio file into speaker segments, and writes the results to the outTel output file.
