Abstract

A voice control method is provided, which includes the following steps. First, a sound signal is received, wherein the sound signal includes a voice signal and a predetermined signal. Next, and electronic device is used to filer the predetermined signal to acquire the voice signal from the sound signal. Next, the voice signal is compared with several sample signals. Finally, the electronic device implements a corresponding action according to the result of the voice comparison. When the voice comparison is successful, the electronic device implements a corresponding control command according to the corresponding sample signal of the voice signal. On the other hand, when the voice comparison fails, the electronic device displays a predetermined string on the frame.

Claims

1. A voice control method, applicable for an electronic device to compare and identify a corresponding sample signal of a voice signal from several sample signals, wherein each of the sample signals corresponds to a different control command respectively, the voice control method comprising:

receiving a sound signal including a voice signal and a predetermined signal;

filtering the predetermined signal to acquire the voice signal from the sound signal;

comparing the voice signal with the several sample signals; and

implementing a corresponding control command by the electronic device according to the corresponding sample signal of the voice signal.

2. The voice control method as claimed in claim 1, wherein the predetermined signal is a sound source signal sent out by the electronic device when the sound signal is received by the electronic device.

3. The voice control method as claimed in claim 1, further comprising a step of displaying a predetermined string on the frame by the electronic device, when the voice comparison fails.

4. The voice control method as claimed in claim 1, further comprising a step of establishing a voice database before the sound signal is received.

5. The voice control method as claimed in claim 4, wherein the step of establishing the voice database comprises the following steps:

selecting a control command from the control commands provided to the electronic device;

receiving a sound reference signal when the control command is received by the electronic device, wherein the sound reference signal comprises a predetermined signal and a sample reference signal;

filtering the predetermined reference signal to acquire the sample reference signal from the sound reference signal; and

storing the sample reference signal into the voice database as one of the sample signals, wherein the stored sample signal corresponds to the control command.

6. The voice control method as claimed in claim 5, wherein the predetermined reference signal is a sound source signal sent out by the electronic device when the sound reference signal is received by the electronic device.
