About the labeling configuration

All labeling configurations must be wrapped in View tags.

Use the Audio object tag with the hotkey argument to allow annotators to play back audio on the labeling interface using a specific hotkey, and use the zoom="true" argument to allow annotators to zoom in on the audio wave:

<Audio name="audio" value="$audio" zoom="true" hotkey="ctrl+enter" />

You can add a header to provide instructions to the annotator:

<Header value="Provide Transcription" />

Use the TextArea control tag to prompt annotators to add a transcript for the audio:

<TextArea name="transcription" toName="audio" rows="4" editable="true" maxSubmissions="1" />

The rows="4" argument lets you configure the size of the text box visible on the labeling interface. The maxSubmissions="1" argument limits the maximum number of transcripts submitted by an annotator for the audio clip to one, while the editable="true" argument allows annotators to edit the transcript.
