| 摘要 |
Methods and apparatus for providing enhanced audio are described. In some embodiments speech synthesis information is used to provide user control of attributes of received broadcast speech, such as language, tone, speed, gender, and volume. In other embodiments, speech synthesis information is transmitted prior to a broadcast audio signal, allowing the receiving node to substitute synthesized speech for the broadcast audio signal if there is an interruption in the audio signal. Still other implementations allow for the synthesizing of speech that is different than the broadcast audio signal, such as background information, associated local information, title, author, etc. Other embodiments allow for the simultaneous transmission of multiple speech programming in a single transmission stream, allowing the user to select one program from the transmitted set of programs for synthesizing speech representative of the selected program.
