Abstract

An audio-book playback method includes buffering text data that is to be played back by speech, converting the buffered text data to speech data, performing speech-playback by using the speech data, and buffering next text data for continuous playback. The provided audio-book playback method and an apparatus enable a user to enjoy reading a book while also listening to content of the book being voiced by a multimedia playback device. Moreover, double buffering technology is employed to provide seamless text and speech-playback services.

Claims

1. An audio-book playback method, comprising:

buffering text data that is to be played back by speech;

converting the buffered text data to speech data;

performing speech-playback by using the speech data; and

buffering next text data that is to be played back by speech.

2. The method of claim 1, wherein the performing of the speech-playback by using the speech data and the buffering of the next text data for continuous playback are performed simultaneously.

3. The method of claim 1, further comprising:

determining whether the data currently in speech-playback is last data, before the buffering of next text data.

4. The method of claim 1, further comprising:

performing TTS (text-to-speech) conversion on the buffered next text data.

5. The method of claim 1, wherein an amount of current data or next data buffered is determined such that seamless playback of the data can be guaranteed.

6. The method of claim 1, wherein an amount of the data buffered in the buffering of text data that is to be played back by speech or the buffering of next text data is determined in consideration of at least one of a storage capacity of the buffer and an amount of data displayable on a display at once.

7. The method of claim 1, further comprising:

performing text-playback,

wherein the performing of the text-playback is synchronized with the performing of the speech-playback.

8. The method of claim 7, wherein text data corresponding to the speech data currently in playback is displayed so as to be distinguishable from other text data.

9. An audio-book playback method, comprising:

selecting an audio-book playback mode; and

based on the selection, performing one of

a text-playback operation, a speech-playback operation and a text and speech-playback operation.

10. The method of claim 9, wherein the speech-playback operation comprises:

buffering text data that is to be played back by speech;

converting the buffered text data to speech data;

performing speech-playback by using the speech data; and

buffering next text data that is to be played back by speech.

11. The method of claim 10, wherein the performing of speech-playback by using the converted speech data and the buffering of next text data are performed simultaneously.

12. The method of claim 10, further comprising:

determining whether the data currently in speech-playback is last data, before the buffering of next text data.

13. The method of claim 10, further comprising:

performing TTS conversion on the buffered next text data.

14. The method of claim 13, wherein the performing of speech-playback by using the speech data and the performing of the TTS conversion on the buffered next text data are performed simultaneously.

15. A computer-readable recordable medium having embodied thereon a computer program to execute a method, the method comprising:

buffering text data that is to be played back by speech;

converting the buffered text data to speech data;

performing speech-playback using the speech data; and

buffering next text data that is to be played back by speech.

16. An audio-book playback apparatus, comprising:

a display to display text data;

a buffer to buffer text data that is to be played back by speech; and

a TTS converter to convert the text data stored in the buffer to speech data,

wherein the audio-book playback apparatus outputs the text data and the speech data simultaneously with buffering text data that is to be played back next.

17. The apparatus of claim 16, wherein an amount of text data stored in the buffer is equal to or greater than an amount of text data to be displayed on the display at once.

18. A portable multimedia playback device, comprising:

a frame; and

an audio-book playback apparatus connected to the frame, the audio-book playback apparatus comprising;

buffering text data that is to be played back by speech;

converting the buffered text data to speech data;

performing speech-playback by using the speech data; and

buffering next text data that is to be played back by speech.

19. An audio-book playback apparatus having a display and a speaker, the apparatus comprising:

a text-viewer function to provide text data to the display to be displayed to a user; and

a book teller function to provide speech data corresponding to the text data to the speaker to be transmitted to the user,

wherein the text data is displayed by the display and the speech data is transmitted by the speaker simultaneously.

20. The apparatus of claim 19, further comprising:

a buffer to buffer a next set of text data and speech data while a previous set of text data and the speech data are being respectively displayed and transmitted.

21. A method of playing back an audio book, the method comprising:

providing text data to be displayed to a user; and

providing speech data corresponding to the text data to be transmitted to the user such that the text data is displayed and the speech data is transmitted simultaneously.
