Abstract

A system and method for using a short message service (SMS) of a wireless communication network operates to convert a subscriber'"'"'s voice to a text message. The system employs offline conversion and verification of the converted text message prior to transmitting the text message over the wireless communication network. The system is implemented within the subscriber unit handset such that no additional infrastructure modifications of the wireless communication network are required.

Claims

1. A text messaging system for a telecommunications device, comprising:

a microphone;

a converting device for converting an output from said microphone into an alphanumeric output;

a display device for displaying said alphanumeric output;

a wireless transmission system having a frequency bandwidth adapted to maximized transmission of said alphanumeric output;

an activation device activated in response to authentication of said displayed alphanumeric output for transmitting said alphanumeric output on said wireless transmission system.

2. The system according to claim 1, wherein said activation device includes a dialing mechanism to direct said alphanumeric output to at least one defined end user.

3. The system according to claim 1, wherein said converting device includes a first memory device for storing said alphanumeric output.

4. The system according to claim 1, wherein said converting device includes a device for associating predefined alphanumeric portions with said output from said microphone.

5. The system according to claim 1, further including a voice recorder for recording the output of said microphone.

6. The system according to claim 1, further including a text to voice system for converting said transmitted alphanumeric output.

7. The system according to claim 1, wherein said wireless transmission system includes a voice transmission function.

8. The system according to claim 1, further including a storage device for storing said transmitted alphanumeric output.

9. The system according to claim 1, wherein said microphone, said display device and said activation devices are integrated in a mobile subscriber unit.

10. A method for wirelessly transmitting text messages via a telecommunications device, comprising:

converting a voice input from a user into a text message;

displaying said text message for the user;

determining whether said displayed text message is satisfactory to the user; and

transmitting said displayed text message over a wireless communication network upon determining that said displayed text message was satisfactory.

11. The method according to claim 10, wherein transmitting said displayed text message over a wireless communication network upon determining that said displayed text was satisfactory includes dialing a numeric code in order to direct said text message to at least one predefined end user.

12. The method according to claim 10, further including storing said text message to be displayed.

13. The method according to claim 10, wherein converting a voice input from a user into a text message includes associating predefined text portions with said voice input.

14. The system according to claim 10, further including recording said voice input.

15. The method according to claim 10, further including converting said transmitted text message to a voice output.

16. The method according to claim 10, further including storing said transmitted text message after determining whether said displayed text message is satisfactory to the user.

17. The method according to claim 10, wherein said converting, displaying, determining and transmitting are performed using a mobile subscriber unit.

18. The method according to claim 14, further including playing back the recorded voice input.

19. A subscriber unit for use with a wireless communication network, said subscriber unit comprising:

a handset housing;

a microphone arranged in the housing;

a voice recognition circuit coupled to said microphone for converting an output of said microphone into text data;

a display coupled to display said text data; and

an activation device for transmitting said text data over said wireless communication network.

20. The subscriber unit according to claim 19, wherein said activation device includes a dialing mechanism.

21. The subscriber unit according to claim 19, wherein said voice recognition circuit includes a first memory device for storing said text data.

22. The subscriber unit according to claim 19, wherein said voice recognition circuit includes a device for associating predefined text portions with said output of said microphone.

23. The subscriber unit according to claim 19, further including a voice recorder for recording the output of said microphone.

24. The subscriber unit according to claim 19, wherein said activation device further includes a memory for storing said transmitted text data.
