Abstract

A headset with a radio communication function is formed by a microphone configured to detect a speech and generate a speech signal indicating the speech, a speech recognition unit configured to recognize the speech indicated by the speech signal, a recognition result transmission unit configured to transmit a recognition result obtained by the speech recognition unit to an external device by radio communication, and a function selecting unit configured to enable a user of the headset to selectively control the speech processing unit to carry out a speech recognition processing of the speech signal generated by the microphone.

Claims

1. A headset with a radio communication function, comprising:

a microphone configured to detect a speech and generate a speech signal indicating the speech;

a speech recognition unit configured to recognize the speech indicated by the speech signal;

a recognition result transmission unit configured to transmit a recognition result obtained by the speech recognition unit to an external device by radio communication; and

a function selecting unit configured to enable a user of the headset to selectively control the speech processing unit to carry out a speech recognition processing of the speech signal generated by the microphone.

2. The headset of claim 1, wherein the function selecting unit enables the user to select whether or not to carry out the speech recognition processing of the speech signal generated by the microphone.

3. The headset of claim 1, further comprising:

a speech transmission unit configured to transmit the speech signal to the external device by radio communication;

wherein the function selecting unit enables the user to select either one of the speech recognition unit and the speech transmission unit to carry out a processing of the speech signal generated by the microphone.

4. The headset of claim 1, further comprising:

a speech transmission unit configured to transmit the speech signal to the external device by radio communication;

wherein the function selecting unit enables the user to select any one of three modes including a mode for carrying out a processing by the speech recognition unit, a mode for carrying out a processing by the speech transmission unit, and a mode for not carrying out a processing by either the speech recognition unit or the speech transmission unit.

5. The headset of claim 1, further comprising:

a speech transmission unit configured to transmit the speech signal to the external device by radio communication;

wherein the function selecting unit enables the user to select any one of three modes including a mode for carrying out a processing by the speech recognition unit, a mode for carrying out a processing by the speech transmission unit, and a mode for carrying out processings by both the speech recognition unit and the speech transmission unit.

6. The headset of claim 1, wherein the speech recognition unit recognizes the speech indicated by the speech signal within the headset and generates an identification signal corresponding to the speech as recognized from the speech signal, and the recognition result transmission unit transmits the identification signal as the recognition result to the external device by the radio communication.

7. The headset of claim 1, wherein the function selecting unit is a switch to be manually operated by the user.

8. A speech processing system, comprising:

a headset with a radio communication function, comprising; and

an external device capable of carrying out radio communication with the headset;

wherein the headset has;

a microphone configured to detect a speech of a user of the headset and generate a speech signal indicating the speech;

a speech recognition unit configured to recognize the speech indicated by the speech signal, and generate an identification signal corresponding to the speech as recognized from the speech signal; and

a recognition result transmission unit configured to transmit the identification signal generated by the speech recognition unit as a recognition result to the external device by radio communication, such that the external device carries out an operation corresponding to the identification signal received from the headset.

9. The speech processing system of claim 8, wherein the external device has a table for storing a plurality of identification signals in correspondence to operations corresponding to respective identification signals.

10. The speech processing system of claim 8, wherein the headset also has a function selecting unit configured to enable the user of the headset to selectively control the speech processing unit to carry out a speech recognition processing of the speech signal generated by the microphone.

11. A speech processing system, comprising:

a headset with a radio communication function, comprising; and

an external device capable of carrying out radio communication with the headset and having a speech recognition function;

wherein the headset has;

a microphone configured to detect a speech of a user of the headset and generate a speech signal indicating the speech;

a headset side speech recognition unit configured to recognize the speech indicated by the speech signal; and

a speech transmission unit configured to transmit the speech signal to the external device by radio communication; and

the external device has;

a speech receiving unit configured to receive the speech signal transmitted from the headset; and

a device side speech recognition unit configured to recognize the speech indicated by the speech signal.

12. The speech processing system of claim 11, wherein the external device carries out an operation corresponding to a recognition result obtained by the device side speech recognition unit.

13. The speech processing system of claim 11, wherein the external device also has a display unit,

the device side speech recognition unit recognizes the speech indicated by the speech signal, generates an identification signal corresponding to the speech as recognized from the speech signal, and outputs a character string converted from the identification signal, such that the display unit of the external device displays the character string as a recognition result of the device side speech recognition unit.

14. A speech processing system, comprising:

a headset with a radio communication function, comprising;

a first external device capable of carrying out radio communication with the headset and having a speech recognition function; and

a second external device capable of carrying out radio communication with the first external device;

wherein the headset has;

a microphone configured to detect a speech of a user of the headset and generate a speech signal indicating the speech;

a headset side speech recognition unit configured to recognize the speech indicated by the speech signal; and

a speech transmission unit configured to transmit the speech signal to the first external device by radio communication; and

the first external device has;

a speech receiving unit configured to receive the speech signal transmitted from the headset;

a device side speech recognition unit configured to recognize the speech indicated by the speech signal, and generate an identification signal corresponding to the speech as recognized from the speech signal; and

a recognition result transmission unit configured to transmit the identification signal as a recognition result to the second external device by radio communication, such that the second external device carries out an operation corresponding to the identification signal received from the first external device.
