Abstract

A solution for text-to-speech conversion is provided. According to the solution, it is checked whether or not a character string comprises a character combination which does not represent a word. If the character string comprises a character combination which does not represent a word, the function of the character combination is analyzed. Based on the analysis, a speech synthesizer is configured to produce a desired speech waveform.

Claims

1. A method of converting text-to-speech in an electronic device, the method comprising:

reading a character string;

checking whether or not the character string comprises a character combination which has a function other than that of representing a word;

analyzing, if a character combination which has a function other than that of representing a word was found, the function of the character combination, and

configuring a speech synthesizer to produce a speech waveform based on the analysis.

2. The method of claim 1, wherein the character combination describes an emotion.

3. The method of claim 2, further comprising configuring, based on the analysis, the speech synthesizer to produce a speech waveform describing the emotion related to the character combination.

4. The method of claim 1, further comprising checking whether or not the character combination is included in a database comprising known character combinations which have a function other than that of representing a word.

5. The method of claim 1, further comprising:

associating the character combination with a word or words preceding the character combination, and

configuring the speech synthesizer to adjust pronunciation of the word or words associated with the character combination according to the analysis of the character combination.

6. The method of claim 1, further comprising configuring the speech synthesizer to play a recorded audio sample according to the analysis.

7. An electronic device comprising:

a speech synthesizer for producing a speech waveform according to input signals;

a control unit connected to the speech synthesizer, the control unit being configured to;

read a character string;

check, whether or not the character string comprises a character combination which has a function other than that of representing a word;

analyze, if a character combination which has a function other than that of representing a word was found, the function of the character combination, and

configure the speech synthesizer to produce a speech waveform based on the analysis.

8. The electronic device of claim 7, wherein the control unit is further configured to analyze whether or not the character combination describes an emotion related to words associated with the character combination.

9. The electronic device of claim 8, wherein the control unit is further configured to configure, based on the analysis, the speech synthesizer to produce a speech waveform describing the emotion related to the character combination.

10. The electronic device of claim 7, wherein the control unit is further configured to check whether or not the character combination is included in a database comprising known character combinations which have a function other than that of representing a word.

11. The electronic device of claim 7, wherein the control unit is further configured to:

associate the character combination with a word or words preceding the character combination, and

configure the speech synthesizer to adjust pronunciation of the word or words associated with the character combination according to the analysis of the character combination.

12. The electronic device of claim 7, wherein the control unit is further configured to configure the speech synthesizer to play a recorded audio sample according to the analysis.

13. The electronic device of claim 7, the electronic device being a text-to-speech conversion unit.

14. An electronic device comprising:

speech synthesizing means for producing a speech waveform according to input signals;

means for reading a character string;

means for checking whether or not the character string comprises a character combination which has a function other than that of representing a word;

means for analyzing, if a character combination which has a function other than that of representing a word was found, the function of the character combination, and

means for configuring the speech synthesizing means to produce a speech waveform based on the analysis.

15. The electronic device of claim 14, wherein the character combination describes an emotion, the electronic device further comprising means for configuring, based on the analysis, the speech synthesizer to produce a speech waveform describing the emotion related to the character combination.

16. A computer program product encoding a computer program of instructions for executing a computer process for converting text-to-speech in an electronic device, the process comprising:

reading a character string;

checking whether or not the character string comprises a character combination which has a function other than that of representing a word;

analyzing, if a character combination which has a function other than that of representing a word was found, the function of the character combination, and

configuring a speech synthesizer to produce a speech waveform based on the analysis.

17. A computer program product of claim 16, wherein the character combination describes emotion, the process further comprising configuring, based on the analysis, the speech synthesizer to produce a speech waveform describing the emotion related to the character combination.

18. A computer program distribution medium readable by a computer and encoding a computer program of instructions for executing a computer process for converting text-to-speech in an electronic device, the process comprising:

reading a character string;

checking whether or not the character string comprises a character combination which has a function other than that of representing a word;

analyzing, if a character combination which has a function other than that of representing a word was found, the function of the character combination, and

configuring a speech synthesizer to produce a speech waveform based on the analysis.

19. A computer program distribution medium of claim 18, wherein the character combination describes an emotion, the process further comprising configuring, based on the analysis, the speech synthesizer to produce a speech waveform describing the emotion related to the character combination.

20. The computer program distribution medium of claim 18, comprising at least one of the following mediums:

a computer readable medium, a program storage medium, a record medium, a computer readable memory, a computer readable software distribution package, a computer readable signal, a computer readable telecommunications signal, a computer readable compressed software package.
