Audio description of controls

摘要

A method is described for audio-descriptions to enable the control of a programme to retrieve data in audio form without the need of a visual display. When a control is selected its function is described via audio together with any additional instructions required. E.g. if a function for selecting the voice to be used as audio output the audio output will state that different voices may be previewed by pressing that function and that to select a specific voice the "ENTER" button must be pressed.
