Audio description is a verbal commentary that explains what is happening on the stage during the parts of the performance where there is no dialogue. The description does not interfere with the performance but fills in the gaps, describing facial expressions, costume, scenery and action sequences so that anyone with a visual impairment can follow the plot fully and independently.

During the performance the trained describer sits in a soundproof booth in the theatre and their description is relayed to theatre-goers via individual headsets. This ensures that the audio description doesn’t interfere with the performance for people who don’t require a verbal commentary.
