Abstract

A pronunciation synthesis system and method. The pronunciation synthesis system may pre-analyze a word to decompose the word into word root(s) and/or affix(es). The pronunciation synthesis system may include at least an analyzing module, a searching module, a pronunciation module, and a synthesizing module. The pronunciation synthesis system may be provided to search for phonetic waveform data that corresponds to the word root or affix so as to automatically synthesize the phonetic waveform data for the word.

Claims

1. A pronunciation synthesis system, comprising:

a database for storing a plurality of word data and phonetic waveform data corresponding to the pronunciations of the word data;

an analyzing module for analyzing the structure of a word and decomposing the word into smaller units, the smaller units being at least one selected from the group consisting of a word root and an affix;

a searching module for searching in the database for word data that are relevant to the decomposed smaller units of the word so as to retrieve the phonetic waveform data of the searched word data;

a segmenting module using syllable as a segmenting unit while referring to the decomposed smaller units of the word to segment the phonetic waveform data retrieved by the searching module in order to obtain pronunciation data that respectively correspond to the pronunciation of the smaller units; and

a synthesizing module for arranging the pronunciation data so that each pronunciation data correspond in place with the location of each of the smaller units of the word to form a pronunciation synthesis of the word.

2. The pronunciation synthesis system as claimed in claim 1, wherein the system is suitable for use in an electronic dictionary.

3. The pronunciation synthesis system as claimed in claim 1, wherein the analyzing module decomposes the word into smaller units according to a word construction rule.

4. The pronunciation synthesis system as claimed in claim 3, wherein the affix comprises prefixes and suffixes.

5. The pronunciation synthesis system as claimed in claim 1, wherein the searching module searches the database for all word data comprising the word root or the affix according to the decomposed word root or affix.

6. The pronunciation synthesis system as claimed in claim 1, wherein the searching module further comprises a sifting unit for comparing all word data searched by the searching module with the smaller units decomposed by the analyzing module so as to select a preferred word data to provide to the segmenting module for further processing.

7. The pronunciation synthesis system as claimed in claim 6, wherein if a word data in the database is determined to match exactly with the one of the smaller units, the word data is the preferred word data for that unit.

8. The pronunciation synthesis system as claimed in claim 6, wherein if a plurality of word data candidates are found, the word data having the fewest letters after subtracting the corresponding smaller unit is the preferred word data for that unit.

9. A pronunciation synthesis method, suitable for use in a pronunciation synthesis system, the method comprising:

(1) providing an analyzing module for analyzing the structure of a word according to a word construction rule and decomposing the word smaller units, the smaller units being at least one selected from the group consisting of a word root and an affix;

(2) providing a searching module for searching a database for word data which correspond to the decomposed smaller units of the word so as to retrieve the phonetic waveform data of the searched word data;

(3) providing a segmenting module using syllable as a segmenting unit while referring to the decomposed smaller units of the word to segment the phonetic waveform data retrieved by the searching module in order to obtain pronunciation data that respectively correspond to the pronunciation of the smaller units; and

(4) providing a synthesizing module for arranging the pronunciation data so that each pronunciation data correspond in place with the location of each of the smaller units within the word to form a pronunciation synthesis of the word.

10. The pronunciation synthesis method as claimed in claim 9, wherein the pronunciation synthesis system is suitable for use in an electronic dictionary.

11. The pronunciation synthesis method as claimed in claim 9, wherein the data produced in each step of the method is stored in a database.

12. The pronunciation synthesis method as claimed in claim 11, wherein the database is further provided to store a plurality of word data and phonetic waveform data corresponding to the pronunciations of the word data.

13. The pronunciation synthesis method as claimed in claim 9, wherein step (1) further comprises analyzing the structure of the word by the analyzing module according to the word construction rule to decompose the word into a word root and at lease one affix.

14. The pronunciation synthesis method as claimed in claim 9, wherein step (2) further comprises the searching module searching the database for all word data comprising the word root and the affix.

15. The pronunciation synthesis method as claimed in claim 14, wherein step (2) further comprises providing a sifting module to compare all word data searched by the searching module with the word root and the affix decomposed by the analyzing module, so as to select a preferred word data to provide to the segmenting module for further processing.

16. The pronunciation synthesis method as claimed in claim 15, wherein in step (2), if the comparison result of the sifting module is that a word data in the database completely matches with the decomposed word root or the affix, the word data is the preferred word data for that word root or affix.

17. The pronunciation synthesis method as claimed in claim 15, wherein in step (2), if a plurality of word data candidates are found, the sifting module determines that, among the plurality of word data, a word data having the same letter construction or fewest difference with the decomposed word root or affix is the preferred word data.
