Abstract

A method of converting a text message into synthesized speech, comprises the steps of: storing a speech synthesis template for synthesizing speech; sending a text message together with an identifier identifying the source of the text message to a recipient of the text message; and sending a copy of the speech synthesis template to the recipient of the text message. In one embodiment of the invention the speech synthesis template is not sent unless it is requested by the recipient of the text message.

Claims

1. A communications device comprising:

a memory for storing a plurality of speech synthesis templates for synthesising speech;

a message handler for receiving a text message together with an identifier identifying at least one speech synthesis template to be used for converting the text message into synthesised speech;

a speech synthesiser for converting the text message into synthesised speech using the at least one identified speech synthesis template; and

an output to provide the synthesised speech.

2. A communications device according to claim 1 wherein the identifier identifies the source of the text message.

3. A communications device according to claim 1 comprising a speech synthesis template handler for receiving a copy of the at least one identified the speech synthesis templates.

4. A communications device according to claim 1 comprising a speech synthesis template handler which is arranged to send a speech synthesis template to one of the following:

a communications device, a communications network and a server.

5. A communications device according to claim 4, wherein the speech synthesis template handler is arranged to send the speech synthesis template when it is requested by one of the following:

a communications device, a communications network and a server.

6. A communications device according to claim 4, wherein the speech synthesis template handler is capable of sending a speech synthesis template which is specific to a designated user of the communications device.

7. A communications device according to claim 4 comprising a transmitter to transmit a text message and a copy of the speech synthesis template to a recipient of the text message.

8. A communications device according to claim 1 comprising a speech handler for artificially reading the text message as synthesised speech using the at least one identified speech synthesis template.

9. A communications device according to claim 1 comprising a transmitter to transmit the synthesised speech over a data communications link.

10. A communications device according to claim 1 comprising a synchronisation unit to transmit synchronisation information between the communications device and a communications network to synchronise data held in the memory with data held in the communications network.

11. A communications device according to claim 1 comprising a message generator for generating a text message.

12. A communications device according to claim 1 which is a mobile device.

13. A communications device according to claim 1 which is a based within a communications network.

14. A communications device according to claim 13 comprising a server.

15. A communications device according to claim 1 comprising a database for storing a plurality of speech synthesis templates.

16. A communications device according to claim 15, wherein the database is arranged to store identifiers which each correspond to one speech synthesis template and one source.

17. A communications device according to claim 1 which is capable of transmitting data over a wireless data communications link.

18. A communications system comprising a communications device and a communications network, the communications system comprising:

a memory for storing a plurality of speech synthesis templates for synthesising speech;

a message handler for receiving a text message together with an identifier identifying at least one speech synthesis templates which is to be used for converting the text message into synthesised speech;

a speech synthesiser for converting the text message into synthesised speech using the at least one identified speech synthesis templates; and

an output to provide the synthesised speech.

19. A communications system according to claim 18 comprising corresponding synchronisation units in the communications device and the communications network to enable data stored in the communication network to be synchronised with data stored in the communications device.

20. A communications system according to claim 18 comprising a speech synthesis template handler for receiving a copy of the at least one identified the speech synthesis templates.

21. A communications system according to claim 18 which is capable of transmitting data over a wireless data communications link between the communications network and the communications device.

22. A method of converting a text message into synthesised speech, the method comprising the steps of:

storing a plurality of speech synthesis templates for synthesising speech;

receiving a text message together with an identifier identifying at least one speech synthesis template which is to be used for converting the text message into synthesised speech;

converting the text message into synthesised speech using the at least one identified speech synthesis template; and

outputting the synthesised speech.

23. A method according to claim 22 in which the identifier identifies the source of the text message.

24. A method according to claim 22 comprising the step of receiving a copy of the identified speech synthesis template.

25. A method according to claim 22 comprising the step of artificially reading the text message in synthesised speech using the identified speech synthesis template.

26. A method according to claim 22 comprising the step of transmitting the synthesised speech over a data communications link.

27. A method according to claim 22 comprising the step of sending a text message and a copy a speech synthesis template to a recipient of the text message.

28. A method according to claim 22 comprising the step of transmitting synchronisation information between a communications device and a communications network to synchronise data held in the communications device with data held in the communications network.

29. A method according to claim 22 comprising the step of transmitting data over a wireless data communications link.

30. A computer program product for converting a text message into synthesised speech, the computer program product comprising:

computer executable code for causing a computer to store a plurality of speech synthesis templates for synthesising speech;

computer executable code for causing a computer to receive a text message together with an identifier identifying which of the plurality of speech synthesis templates is to be used for converting the text message into synthesised speech;

computer executable code for causing a computer to convert the text message into synthesised speech using a selected one of the speech synthesis templates; and

computer executable code for causing a computer to output the synthesised speech in a signal to be played by a microphone.

31. A computer program product according to claim 30 which is stored on a computer readable medium.
