Rotation and tilting of a display using voice information

A voice control method applied to a voice control device, the voice control device comprising a display and a camera module;

• the method comprising:
• (a) receiving a voice signal;
• (b) processing the voice signal to determine a sound source direction of the voice signal;
• (c) analyzing the voice signal to obtain a response information;
• (d) controlling the display to rotate to the sound source direction;
• (e) activating the camera module to capture an image after the display is rotated to the sound source direction;
• (f) determining whether a user feature is in the image captured by the camera, and adjusting a tilting angle of the display according to a location of the user feature in the captured image;
• and
• (g) transmitting the response information to the display for displaying the response information.

A voice control system, comprising:

• a network server;
• and
• a voice control device, comprising:
• a microphone module for receiving a voice signal;
• a voice encoding module electrically connected to the microphone module;
• a display;
• a processing unit electrically connected to the voice encoding module and the display;
• and
• a camera module electrically connected to the processing unit and positioned on the display;
• wherein the microphone module transmits the voice signal to the voice encoding module, and one of the voice encoding module and the processing unit analyzes and processes the voice signal to determine a sound source direction of the voice signal and obtains response information according to the voice signal;
• wherein the processing unit controls the display to rotate to the sound source direction and transmits the response information to the display for displaying the response information;
• wherein the processing unit controls the display to rotate to the sound source direction and activates the camera module to capture an image after the display is rotated to the sound source direction,
• wherein the processing unit determines whether a face feature is in the image and adjusts a tilting angle of the display according to a location of the face feature in the image captured by the camera and transmits the response information to the display for displaying the response information.
