Abstract

Tonal transformation of speech is provided. A tone applicable to a syllable of received speech is determined. A tonal contour applicable to said tone for a dialect of a listener is determined, and the syllable of received speech is altered to have said determined tonal contour. The altered speech may then be delivered to the listener.

Claims

1. A method for the tonal transformation of speech, comprising:

receiving speech from a first user including a first syllable spoken in a first dialect;

identifying said first syllable included in said received speech;

determining a tonal contour of said first syllable;

determining a tonal contour for said first syllable according to a second dialect spoken by a second user;

modifying said first syllable included in said received speech to create modified speech, wherein said modified speech has said tonal contour for said first syllable according to said second dialect spoken by said second user.

2. The method of claim 1, further comprising:

delivering said modified speech to said second user.

3. The method of claim 1, further comprising:

determining said first dialect spoken by said first user;

determining said second dialect spoken by said second user.

4. The method of claim 3, wherein said determining said first dialect spoken by said first user and said second dialect spoken by said second user comprises receiving a signal from at least one of said first user and said second user indicating at least one of said first and second dialects.

5. The method of claim 3, wherein said determining a dialect spoken by at least one of said first user and said second user comprises receiving a pronunciation of at least a first word from said at least one of said first user and said second user and determining a tonal contour applied to said at least a first word.

6. The method of claim 5, wherein said at least a first word is predetermined.

7. The method of claim 5, wherein said at least a first word is identified using a speech recognition application.

8. The method of claim 3, wherein said determining a dialect spoken by at least one of said first user and said second user comprises inferring a dialect from at least one of an area code and a geographic location of a communication device associated with said at least one of said first and second user.

9. The method of claim 1, wherein said determining a tonal contour comprises:

determining a tone of said first syllable;

referencing a tone contour table;

locating in said tone contour table a tonal contour applicable to said determined tone according to said second dialect spoken by said second user.

10. The method of claim 1, wherein said first syllable is identified using a speech recognition application.

11. A system for the tonal modification of speech, comprising:

a user input, operable to receive speech;

a memory, wherein said memory stores tonal contours for each of a plurality of tones and for each of a plurality of dialects including at least first and second dialects;

a processor, wherein in response to receipt of speech comprising at least a first received syllable having a first tonal contour according to said first dialect of a language, said first received syllable is modified to form a first modified syllable having a second tonal contour according to said second dialect of said language.

12. The system of claim 11, wherein said memory stores said tonal contours in a table, and wherein said table maps a tone of said first received syllable to a tonal contour applicable for said first received syllable according to said second dialect of said language.

13. The system of claim 11, further comprising:

a communication interface interconnected to said processor;

a communication network interconnected to said communication interface and to a plurality of addresses, wherein said first modified syllable is released for delivery to a recipient address.

14. The system of claim 13, wherein said user input receives said speech further comprising:

a user output, wherein said first modified syllable is presented to a user.

15. The system of claim 14, wherein said user output includes a speaker, and wherein said first modified syllable is presented to said user as speech.

16. The system of claim 14, further comprising:

a first communication device, wherein said user input is provided as part of said first communication device; and

a second communication device, wherein said user output is provided as part of said second communication device.

17. The system of claim 16, wherein said first and second communication devices comprise telephony devices, said system further comprising:

a server, wherein said server comprises said memory and said processor.

18. A system for modifying a dialect of tonal speech, comprising:

means for receiving speech as input;

means for determining a tone of a syllable included in received speech;

means for storing tonal contours associated different tones for a number of different dialects of a language;

means for altering a tonal contour of at least a first syllable included in said first received speech to create transformed speech, wherein a tonal contour of said at least a first syllable is changed from a tonal contour from a tonal contour for a tone of said first syllable corresponding to a first dialect of a first language to a tonal contour for said tone of said first syllable corresponding to a second dialect of said first language.

19. The system of claim 18, further comprising:

means for outputting said transformed speech to a user.

20. The system of claim 18, further comprising:

means for delivering said transformed speech to a recipient address.
