Abstract

The present invention proposes a voice control method and a device thereof. A single-key pushbutton is used to control operations of a voice command module and a voice control host. A voice input unit is used to input voice command message given out by a user, and convert it into digital information. The voice command module receives the voice command message of the voice input unit, and compares pre-stored voice command messages to generate a corresponding voice command code and a preset voice command message. The voice control host receives the preset voice command message and the corresponding voice command code, and controls action of a controlled equipment according to the voice command code. A voice output unit converts the preset voice message sent out by the voice control host into an analog signal, and amplifies and outputs them, thereby guiding the user or giving out a voice control command.

(d) said voice control host giving out a preset voice command message;

(e) judging whether said single-key pushbutton is pressed again by the user;

performing the next step if the answer is positive;

otherwise jumping back to Step (c);

(f) ending said browsing function of voice command.

4. The voice control method utilizing a single-key pushbutton to control voice commands as claimed in claim 1, the flowchart of said adding function of said single-key pushbutton comprising the steps of:

(a) pressing said single-key pushbutton for longer than 2 seconds and then releasing it to activate said adding function;

(b) said voice command module sending preset voice command messages in said voice command database one by one to said voice control host;

(c) said voice control host giving out a voice command message to guide the user;

(d) the user giving out a voice command message;

(e) said voice command module converting said voice command message into digital information;

(f) said voice command module storing said digital information into said voice command database;

(g) corresponding said added voice command message to a voice command code;

(h) judging whether a new voice command is added again, jumping back to Step (b) if the answer is positive;

otherwise performing the next step;

(i) ending said adding function of voice command.

5. The voice control method utilizing a single-key pushbutton to control voice commands as claimed in claim 4, wherein said adding function can further comprise a certification procedure between Step (f) and Step (g), said certification procedure comprising the steps of:

(j) said voice control host giving out a preset voice message to guide the user to say the added voice command once again;

(k) the user giving out the voice command message once again;

(l) said voice command module converting the voice command message of the user into digital information;

(m) said voice command module comparing said digital information with the previously stored voice command message;

(n) judging whether they are agreeable, jumping to Step (g) if the answer is positive;

otherwise performing the next step;

(o) said voice control host giving out a preset adding error message;

(p) jumping back to Step (c) for performing said adding function of voice anew.

6. The voice control method utilizing a single-key pushbutton to control voice commands as claimed in claim 1, the flowchart of said deleting function of said single-key pushbutton comprising the steps of:

(a) pressing said single-key pushbutton for longer than 3 seconds and then releasing it to activate said deleting function;
