# Configure Speaker Clustering

To configure speaker clustering

1. Create a new configuration to send to Media Server with the `process` action, or open an existing configuration that you want to modify.

2. In the `[Session]` section, add a new analysis task by setting the `EngineN` parameter. You can give the task any name, for example:

       [Session]
       Engine0=Ingest
       Engine1=SpeakerClustering

3. Create a new section to contain the settings for the task, and set the following parameters:

   `Type` | The analysis engine to use. Set this parameter to `ClusterSpeech`.
   `Input` | (Optional) The audio track to process. If you do not specify an input track, Media Server processes the first track of the correct type produced by the ingest engine.
   LanguagePack | (Required) The language pack to use.
   MaxSpeakers | (Optional) The maximum number of people who speak in the audio or video file. For example, if you know that an audio file contains no more than four speakers, set `MaxSpeakers=4`.
   MinSpeakers | (Optional) The minimum number of people who speak in the audio or video file.
   FixTime | (Optional, default `8 minutes`) A fixed time duration for speaker clustering. For example, if you are processing a media file that is 30 minutes in length you can crystallize the speaker information after five minutes. Any subsequent speech segments are then assigned to one of the speakers from the first five minutes of the file (Media Server does not consider that they could represent new speakers). This increases the speed of classification for the rest of the file. To switch off this functionality, set this parameter to `0`.

   For example:

       [SpeakerClustering]
       Type=ClusterSpeech
       LanguagePack=ENUK
       MaxSpeakers=4
       MinSpeakers=4
       FixTime=10 minutes

   For more information about the parameters that you can use to configure this task, see Speaker Clustering.

4. Save and close the configuration file. OpenText recommends that you save your configuration files in the location specified by the `ConfigDirectory` parameter.
