Abstract

A voice-controlled data system is providing that has a storage medium for storing media files, the media files having associated file identification data for allowing the identification of the media files, the file identification data including phonetic data having phonetic information corresponding to the file identification data. The phonetic data is supplied to a speech recognition unit that compares the phonetic data to a speech command input into the speech recognition unit. The data system further includes a file selecting unit that selects one of the media files based on the comparison result.

Claims

1. Voice-controlled data system comprising a storage medium for storing media files, the media files having associated file identification data for allowing the identification of the media files, the file identification data comprising phonetic data including phonetic information corresponding to the file identification data, the phonetic data being supplied to a speech recognition unit that compares the phonetic data to a speech command input into the speech recognition unit, the data system further comprising a file selecting unit that selects one of the media files based on the comparison result.

2. The data system of claim 1, where the phonetic data of each media file are part of the media file.

3. The data system of claim 1, where the file identification data includes information selected from the group consisting of a title of the file, artist of the file, author of the file, composer of the file, and combinations of two or more of this information.

4. The data system of claim 1, where the phonetic data comprise a phonetic transcription of at least part of the file identification data.

5. The data system of claim 4, where the phonetic data comprise different phonetic transcriptions of one term of the file identification data.

6. The data system of claim 4, where the phonetic data comprise either the phonetic notations of the title of the media file, the interpreter of the media file or a combination of both the notations of the title and the interpreter of the media file.

7. The data system of claim 1, where the media files comprise either audio files, video files or a combination of both audio or video files.

8. The data system of claim 1, where the media files are stored on the storage medium in a compressed format.

9. The data system of claim 5, where the different phonetic transcriptions of one term of the file identification data are generated by applying pronunciation rules of different languages for the term.

18. Multimedia system comprising a data base system of claim 1 and a media file player for playing the selected media files.

10. The data carrier comprising media files, the media files having associated file identification data for allowing the identification of the media files, the file identification data comprising phonetic data including phonetic information corresponding to the file identification data, the phonetic data being supplied to a speech recognition unit, where one of the media files is selected based on a speech control command recognized by the speech recognition unit on the basis of the phonetic data.

11. The data carrier of claim 10, where the phonetic data of each media file are part of the media file.

12. The data carrier of claim 10, where the file identification data includes information selected from the group consisting of a title of the file, artist of the file, author of the file, interpreter of the file, genre of the file and combinations of two or more of this information.

13. The data carrier of claim 10, where the phonetic data comprise a phonetic transcription of at least part of the file identification data.

14. The data carrier of claim 13, where the phonetic data comprise different phonetic transcriptions of one term of the file identification data.

15. The data carrier of claim 13, where the phonetic data comprise either the phonetic transcription of the title, the interpreter of the media file or a combination of both the transcription of the title and the interpreter of the media file.

16. The data carrier of claim 10, where the media files comprise either audio files, video files, or a combination of both audio or video files.

17. The data carrier of claim 10, where the media files are stored on the data carrier in a compressed format.

19. Multimedia system comprising a data carrier of claim 10 and a media file player for playing the selected media files.

20. Method for a voice-controlled selection of a media file stored on a data storage unit comprising a plurality of media files, the media files having associated file identification data, the file identification data comprising phonetic data which include phonetic information corresponding to the file identification data, the method comprising the following steps:

inputting voice data for selecting one of the media files;

supplying the voice data to a speech recognition unit;

extracting the phonetic data from the file identification data;

supplying the phonetic data to the speech recognition unit as recognition vocabulary;

comparing the input voice data to the extracted phonetic data, and generating a corresponding speech control command; and

selecting a media file from the data storage unit in accordance with the generated speech control command.

21. Method for generating media files, the media files comprising media data and file identification data, with the following steps:

providing a phonetic transcription of at least part of the file identification data; and

adding the phonetic transcription to the file identification data.
