Abstract

A portable wireless-enabled system includes an input transducer (for example, a microphone), an output transducer (for example, a speaker) and a wireless transceiver system. Also included, is a memory having a programmable user speech profile. A processor system controls operation of the input transducer, the output transducer, the wireless transceiver system and the memory.

Claims

1. A portable wireless-enabled system comprising:

an input transducer;

a wireless transceiver system;

a memory having a programmable user-trained speech recognition (SR) profile; and

a processor system configured to control operation of the input transducer, the wireless transceiver system and the memory,

wherein the programmable user-trained SR profile is transferable to an external SR-enabled personal computer (PC), which carries out speech recognition functions using of the programmable user-trained SR-profile, and

wherein the memory further comprises synchronization software configured to carry out synchronization of the programmable user-trained SR profile with the SR-enabled PC, and

wherein the memory is non-volatile.

2. The system of claim 1 wherein the input transducer is a microphone.

3. The system of claim 1 and further comprising an output transducer.

4. The system of claim 3 wherein the output transducer is a speaker.

5. The system of claim 1 wherein the input transducer, the wireless transceiver system, the memory having the programmable user-trained SR profile and the processor system are a part of a headset.

6. The system of claim 5 wherein the headset further comprises a SR on/off button to enable/disable communication of speech signals from the headset to a SR application running on the SR-enabled PC.

7. The system of claim 1 wherein the input transducer, a first wireless transceiver of the wireless transceiver system and a first processor of the processor system are a part of a headset, and wherein a second wireless transceiver of the wireless transceiver system, the memory having the programmable user-trained SR profile and a second processor system of the processor system are a part of a wireless adapter.

8. The system of claim 7 wherein the wireless adapter is configured to plug into a computer port of the SR-enabled PC.

9. The system of claim 1 wherein the input transducer, a first wireless transceiver of the wireless transceiver system, the memory having the programmable user-trained SR profile and a first processor of the processor system are a part of a headset, and wherein a second wireless transceiver of the wireless transceiver system and a second processor of the processor system are a part of a wireless adapter.

10. The system of claim 9 wherein the wireless adapter is configured to plug into a computer port of the SR-enabled PC.

11. The system of claim 5 wherein the headset is configured to communicate with a non-wireless enabled PC via a wireless-enabled PC that is coupled the non- wireless enabled PC and wherein the SR-enabled PC is the non-wireless enabled PC.

12. The system of claim 5 wherein the headset is configured to communicate via a wireless communication link with multiple wireless-enabled PCs and wherein the SR-enabled PC is one of the multiple wireless-enabled PCs.

13. A wireless adapter comprising:

a wireless transceiver;

a memory having a programmable user-trained SR profile; and

a processor system configured to control the wireless transceiver and the memory,

wherein the programmable user-trained SR profile is transferable to an external SR-enabled PC, which carries out speech recognition functions using of the programmable user-trained SR-profile, and

wherein the memory further comprises synchronization software configured to carry out synchronization of the programmable user-trained SR profile with the SR-enabled PC, and

wherein the memory is non-volatile.

14. The adapter of claim 13 wherein the wireless transceiver is configured to receive speech signals from a headset via a wireless communication link.

15. The adapter of claim 13 and further comprising a connector configured to plug into a computer port of the SR-enabled PC.

16. The adapter of claim 13 wherein the processor is configured to transfer the programmable user-trained SR profile to the SR-enabled PC upon connection of the wireless adapter to the SR-enabled PC.

17. A headset comprising:

a memory having a programmable user-trained SR profile; and

a processor configured to control operation of the memory,

wherein the programmable user-trained SR profile is transferable to an external SR-enabled PC, which carries out speech recognition functions using of the programmable user-trained SR-profile, and

wherein the memory further comprises synchronization software configured to carry out synchronization of the programmable user-trained SR profile with the SR-enabled PC, and

wherein the memory is non-volatile.

18. The headset of claim 17 wherein the programmable user-trained SR profile in the memory can be accessed by the SR-enabled PC upon connection of the headset to the SR-enabled PC.
