Audio player for reproducing writing data as audio signals

Abstract

An audio player is capable of reading written data of introduction parts of groups of sentences written on a recording medium. The audio player includes a reading section for reading written data and a retrieving table. The retrieving table includes data indicating interrelationships between each group of sentences and a reproduction-starting position for each group. An input section allows inputting a command for reading an introduction part of the group of sentences. A memory section is provided for storing the retrieving table. An audio reproducing section converts the written data into audio signals, and a control section oversees the retrieving, reading, and reproducing of the written data.

Description

(1) Technical field [0001] The present invention relates to a sound reproduction apparatus for reproducing written data recorded as audio signals on a recording medium such as a compact disc read only (CD-ROM). (2) Background technology [0002] Usually, people call the playback device capable of reproducing written data as an audio signal "audiobook", and it is especially used for reading by the blind. Ordinary audiobooks play cassette tapes, so write data is sequentially read by the device. [0003] In order to select and listen to the audio signal (voice) written on the cassette tape as write data, the target write data is retrieved by listening to a tone signal (tune signal) when the cassette tape is played normally is inaudible to our ears, but is audible when the cassette is fast-forwarded or rewound. [0004] However, ordinary audio books have disadvantages as described below. [0005] The mono signal is heard by fast forwarding or rewinding, so it is difficult to ...
