Abstract

A mobile wireless communications device may include a housing and a wireless transceiver carried by the housing. The mobile wireless communications device may also include audio transducer carried by the housing, and a controller cooperating with the wireless transceiver to perform at least one wireless communications function. The controller may also cooperate with the at least one audio transducer to convert speech input through the audio transducer to converted text, determine a proposed modification for the converted text, and output from the audio output transducer the proposed modification for the converted text.

Claims

1. A mobile wireless communications device comprising:

a wireless transceiver;

at least one audio transducer; and

a controller cooperating with the wireless transceiver and the at least one audio transducer, and configured to

convert speech input through the at least one audio transducer to converted text,

determine a proposed modification for the converted text, wherein the proposed modification comprises a proposed ambiguity resolution,

output from the at least one audio transducer the proposed modification for the converted text, and

wirelessly transmit the converted text via the wireless transceiver based upon a spoken command.

2. The mobile wireless communications device according to claim 1 wherein the proposed modification comprises a proposed grammar correction.

3. The mobile wireless communications device according to claim 1 wherein said controller is configured to accept or reject the proposed modification for the converted text based upon a further speech input.

4. The mobile wireless communications device according to claim 1 wherein said controller is configured to selectively play back the converted text.

5. The mobile wireless communications device according to claim 1 further comprising a memory;

and wherein said controller also cooperates with said memory to store the converted text.

6. The mobile wireless communications device according to claim 1 further comprising a memory coupled to said controller for storing text modification rules.

7. A mobile wireless communications device comprising:

a wireless transceiver;

at least one audio transducer; and

a controller cooperating with the wireless transceiver and the at least one audio transducer, and configured to

convert speech input through the at least one audio transducer to converted text,

determine a proposed modification for the converted text, wherein the proposed modification comprises a proposed ambiguity resolution,

output from the at least one audio transducer the proposed modification for the converted text,

accept or reject the proposed modification for the converted text based upon a further speech input, and

wirelessly transmit the converted text via the wireless transceiver based upon a spoken command.

8. The mobile wireless communications device according to claim 7 wherein the proposed modification comprises a proposed grammar correction.

9. The mobile wireless communications device according to claim 7 wherein said controller is configured to selectively play back the converted text.

10. The mobile wireless communications device according to claim 7 further comprising a memory;

and wherein said controller also cooperates with said memory to store the converted text.

11. The mobile wireless communications device according to claim 7 further comprising a memory coupled to said controller for storing text modification rules.

12. A method of upgrading a mobile wireless communications device comprising a wireless transceiver, at least one audio transducer, and a controller cooperating with the wireless transceiver and the at least one audio transducer, the method comprising:

configuring the controller to cooperate with the at least one audio transducer to

convert speech input through the at least one audio transducer to converted text,

determine a proposed modification for the converted text, wherein configuring the controller to determine the proposed modification comprises configuring the controller to determine a proposed ambiguity resolution,

output from the at least one audio transducer the proposed modification for the converted text to thereby upgrade the mobile wireless communications device, and

wirelessly transmit the converted text via the wireless transceiver based upon a spoken command.

13. The method according to claim 12 wherein configuring the controller to determine the proposed modification comprises configuring the controller to determine a proposed grammar correction.

14. The method according to claim 12 wherein configuring the controller further comprises configuring the controller to accept or reject the proposed modification for the converted text based upon a further speech input.

15. The method according to claim 12 wherein configuring the controller further comprises configuring the controller to selectively play back the converted text.
