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 which provides speech signals, a first input unit generating a speech recognition request signal, and a second input unit generating a microphone request signal; and

a receiving host, having;

a speech recognition functional module providing a speech recognition function, wherein the speech recognition functional module recognizes the speech signals received from the microphone of the remote controller;

a microphone functional module providing a microphone function, wherein when the receiving host receives the microphone request signal from the remote controller, the microphone functional module is activated;

wherein;

the speech signals, the microphone request signal and the speech recognition request signal are sent from the remote controller to the receiving host and when the receiving host receives the speech recognition request signal from the remote controller, the speech recognition functional module is activated to recognize the speech signals that are received from the remote controller, and when the receiving host receives the microphone request signal from the remote controller, the microphone functional module is activated;

wherein the receiving host selectively performs the speech recognition function and the microphone function to process the speech signals;

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

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

5. 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 method for remote control of receiving host, wherein the receiving host provides a speech recognition function and a microphone function, a microphone request signal generated by a remote controller for controlling the microphone function of the receiving host, and a speech recognition request signal generated by the remote controller for controlling the speech recognition function of the receiving host, the method comprising:

upon receiving the microphone request signal, selectively activating, by the receiving host, the microphone function, such that speech signals from the remote controller are received by 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 request signal, selectively activating, by the receiving host, the speech recognition function for recognizing the speech signals received from 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 the 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.

7. A receiving host, adapted to a remote controller having a microphone which provides speech signals, and the remote controller independently generates a microphone request signal by a first input unit and a speech recognition request signal by a second input unit, and the speech signals, the microphone request signal and the speech recognition request signal are sent from the remote controller to the receiving host, the receiving host comprising:

a speech recognition functional module providing a speech recognition function; and

a microphone functional module providing a microphone function, and when the receiving host receives the speech recognition request signal from the remote controller, the speech recognition functional module is activated to recognize the speech signals that received from the remote controller, and when the receiving host receives the microphone request signal from the remote controller, the microphone functional module is activated;

wherein the receiving host selectively performs the speech recognition function and the microphone function to process the speech signals;

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

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