<p>The system allows radio broadcast listeners to use a telephone to connect to a database that contains prerecorded audio descriptions (e.g. spoken text and/or music) of material played by the radio station. The database is indexed by the radio station's program schedule or play-list to allow the user to select a particular audio description of interest (e.g. the song currently airing, the song last played, etc.). Hearing the audio description over the telephone ensures the listener that the requested selection is in fact correct. By using the telephone DTMF touch tone controls, the listener can place an order to purchase the selected material over the telephone.</p> |
