# SegmentWav

The `SegmentWav` task segments an audio file by speaker. The task does not require any speaker identification information because HPE IDOL Speech Server estimates speaker changes from changes in the audio.

## Parameters

Parameter | Description | Required
--- | --- | ---
Type | The task name. Set to `SegmentWav`. | Yes
File | The audio file to process. | Yes
MaxSeg | The maximum duration of an audio segment in seconds. |
MinSeg | The minimum duration of an audio segment in seconds. |
NormFile | The acoustic normalization file (.ian file from language pack) to use. | Yes
Out | The file to write the results to. | Yes
Sensitivity | Controls the number of segments that are produced. |

## Example

    http://localhost:13000/action=AddTask&Type=SegmentWav&File=C:\Data\Speech.wav&NormFile=C:\LP\ver-ENUK-5.0-16k.ian&Out=SpeakerChanges.ctm

This action uses port `13000` to instruct HPE IDOL Speech Server, which is located on the local machine, to estimate speaker changes in the `Speech.wav` file and to write the results to the `SpeakerChanges.ctm` file.
