    /action=ListSpeakers&database=news

                        &metadata=true

## Response

The following XML is an example response:

    <autnresponse>
      <action>LISTSPEAKERS</action>
      <response>SUCCESS</response>
      <responsedata>
        <entry>
          <identifier>newsreader</identifier>
          <numaudio>2</numaudio>
          <numtrained>2</numtrained>
          <numfailed>0</numfailed>
          <numuntrained>0</numuntrained>
          <audios>
            <audio>
              <label>0fa6fc519bce4bdf81c335b04c23ed1b</label>
              <status>trained</status>
              <hasaudiodata>true</hasaudiodata>
            </audio>
            <audio>
              <label>70eca429eac320c4cc812488c2adc7d8</label>
              <status>trained</status>
              <hasaudiodata>true</hasaudiodata>
            </audio>
          </audios>
          <metadata>
            <item>
              <key>category</key>
              <value>newsreaders</value>
            </item>
          </metadata>
        </entry>
        ...
      </responsedata>
    </autnresponse>

The response can include the following information for each speaker:

- `identifier` - The identifier for the speaker.
- `numaudio` - The total number of audio samples.
- `numtrained` - The number of audio samples successfully used for training.
- `numfailed` - The number of audio samples for which training was attempted but failed.
- `numuntrained` - The number of audio samples for which training has not yet been attempted.

- `audios` - Each `audio` element describes an audio sample that is associated with the speaker. This information is only present in the response when you set the action parameter `audiostatus=true`.

  - The `label` element provides the label for the audio sample.

  - The `status` element indicates the status of training:

    - `trained` indicates that training was successful.
    - `untrained` indicates that training has not been attempted. To run training use the action BuildSpeaker or BuildAllSpeakers.
    - `failed` indicates that Media Server could not use the audio for training. To remove the failed audio sample use the action RemoveSpeakerAudio.
  - The `hasaudiodata` element indicates whether the audio sample is stored in the database. If this element contains the value `false`, the audio sample has been discarded and only the training is stored in the database. See NullSpeakerAudioData.
- `metadata` - Custom metadata that you added to the speaker. To see the metadata you must set the action parameter `metadata` to `TRUE`.
