# Display Task Details

To retrieve information about a particular task, including the task schema and available parameters, send a `TaskHelp` action to HPE IDOL Speech Server.

To display information about a task

- Send the `TaskHelp` action to HPE IDOL Speech Server, and set the following parameter:

  `Type` | The task name.

For example:

    http://localhost:13000/action=TaskHelp&Type=WavToText

This action uses port `13000` to instruct HPE IDOL Speech Server, which is located on the local machine, to return details about the `WavToText` task.

HPE IDOL Speech Server returns task information as plain text. For example:

    Task: wavToText

    Depending on the resources that the task uses, there might be additional
    parameters that are not listed here.

    For a description of each parameter, see the HPE IDOL Speech Server Reference.

Note: If a task uses one or more resources, you can sometimes set additional parameters depending on the resource configuration. Sometimes the additional parameters are mandatory. The additional parameters are determined after you have specified the resources for a task, therefore they do not appear in the Parameters table.
