Problems solved by technology

[0007] In addition, in ordinary devices, people know the writing data being read by checking the label of the tape or the tape count, so it is difficult to accurately search for the starting point of the sentence group or retrieval unit

Embodiment Construction

[0035] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] First refer to figure 1 The basic structure and operation outline of the sound playback device of this embodiment will be described. Note that although a CD-ROM is used as a randomly accessible recording medium in the sound playback device 10 of this embodiment, a floppy disk and an integrated circuit (IC) card including a semiconductor element such as RAM may also be used as the recording medium. recording medium.

[0037] Writing data of books and a lookup table 14 are stored in the CD-ROM 12 . Write data is stored as an audio file (audiofile). The written data is divided into a plurality of sentence groups (each group including the title sentence of the group of sentences) as retrieval units. The data of the table of contents is constituted by title. The data in Table 14 indicates the audio file (see image 3 ) and the intrinsic...

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 ...
