Abstract

Remote controllers and systems thereof are disclosed. The remote controller remotely operates a receiving host, in which the receiving host provides voice input and speech recognition functions. The remote controller comprises a first input unit and a second input unit for generating a voice input request and a speech recognition request. The generated voice input and speech recognition requests are then sent to the receiving host, thereby forcing the receiving host to perform the voice input and speech recognition functions.

Claims

1. A remote control system, comprising:

a remote controller having a microphone, a first input unit having a first actuator and a second input unit having a second actuator,

the first input unit being operative to generate a speech recognition request signal;

the second input unit being operative to generate a microphone request signal; and

a receiving host, having;

a speech recognition functional module, providing a speech recognition function, wherein the receiving host receives the speech recognition request signal from the remote controller to drive the speech recognition functional module to activate the speech recognition function so as to recognize speech signals received from the microphone of the remote controller after the speech recognition function is activated; and

a microphone functional module, providing a microphone function, wherein the receiving host receives the microphone request signal from the remote controller to drive the microphone functional module to activate the microphone function,

wherein the speech signals received from the microphone of the remote controller are being provided to the receiving host, and the speech recognition request signal and the microphone request signal are independently generated by the remote controller and then sent to the receiving host, such that the receiving host selectively performs the speech recognition function and the microphone function to process the speech signals;

wherein;

in a first mode of operation of the receiving host, the microphone function is activated and the speech recognition function is deactivated; and

in a second mode of operation of the receiving host, the microphone function is activated and the speech recognition function is activated.

2. The remote control system of claim 1, wherein the remote controller further comprises:

a first signal transceiver, transmitting the microphone request signal or the speech recognition request signal to the receiving host; and

a second signal transceiver, transmitting the speech signals to the receiving host.

3. The remote control system of claim 2, wherein the first signal transceiver is an infra-red signal transceiver and the second signal transceiver is a radio frequency signal transceiver.

4. The remote control system of claim 1, wherein the receiving host further comprises:

a storage unit, storing database having at least one recognition pattern.

5. The remote control system of claim 4, wherein the receiving host further comprises a processing unit and when receiving data to be recognized from the remote controller, the processing unit compares the received data with the at least one recognition pattern of the database and activates a corresponding function when finding a matched item in the database.

10. The remote control system of claim 1, wherein the microphone signal is transmitted from the remote controller to the receiving host for controlling the microphone function of the receiving host.

11. The remote control system of claim 1, wherein the receiving host further receives a speech-related command from a user for performing a speech-controlling operation after the speech recognition function has been activated.

6. A remote controller for remote control of a receiving host, the remote controller comprising:

a microphone;

a first input unit having a first actuator, being operative to generate a microphone signal for controlling the microphone function of the receiving host; and

a second input unit having a second actuator, being operative to generate a speech recognition signal for controlling the speech recognition function of the receiving host;

wherein the receiving host has a speech recognition functional module and a microphone functional module, the speech recognition functional module providing a speech recognition function, wherein the receiving host receives the speech recognition request signal from the remote controller to drive the speech recognition functional module to activate the speech recognition function so as to recognize speech signals received from the remote controller after the speech recognition function is activated, the microphone functional module providing a microphone function, wherein the receiving host receives the microphone request signal from the remote controller to drive the microphone functional module to activate the microphone function;

wherein speech signals received from the microphone of the remote controller are being provided to the receiving host, and the remote controller independently generates the microphone signal and the speech recognition signal to send to the receiving host, such that the receiving host selectively performs the speech recognition function and the microphone function to process the speech signals;

wherein;

in a first mode of operation of the receiving host, the microphone function is activated and the speech recognition function is deactivated; and

in a second mode of operation of the receiving host, the microphone function is activated and the speech recognition function is activated.

7. The remote controller of claim 6, further comprising an indicator light for indicating the execution status of the microphone function or the speech recognition function for users.

8. The remote controller of claim 6, further comprising:

a first signal transceiver, transmitting the microphone signal or the speech recognition signal to the receiving host; and

a second signal transceiver, transmitting the speech signals to the receiving host.

9. The remote controller of claim 8, wherein the first signal transceiver is an infra-red signal transceiver and the second signal transceiver is a radio frequency signal transceiver.

12. A method for remote control of a receiving host, wherein the receiving host provides a speech recognition function and a microphone function, the method comprising:

generating, by a remote controller, a microphone signal for controlling the microphone function of the receiving host;

generating, by the remote controller, a speech recognition signal for controlling the speech recognition function of the receiving host;

upon receiving the microphone signal independently generated by the remote controller, selectively activating, by the receiving host, the microphone function such that speech signals received from the microphone of the remote controller are provided to the receiving host, wherein for the microphone function the receiving host receives a microphone request signal from the remote controller to activate the microphone function; and

upon receiving the speech recognition signal independently generated by the remote controller, selectively activating, by the receiving host, the speech recognition function for recognizing speech signals received from the microphone of the remote controller, wherein for the speech recognition function, the receiving host receives a speech recognition request signal from the remote controller to activate the speech recognition function so as to recognize speech signals received from the remote controller after the speech recognition function is activated;

wherein;

in a first mode of operation of the receiving host, the microphone function is activated and the speech recognition function is deactivated; and

in a second mode of operation of the receiving host, the microphone function is activated and the speech recognition function is activated.
