1. Field of the Invention
The present invention relates to a voice control device and voice control method and display device, and more particularly, to a voice control device and voice control method and display device capable of enhancing utilization convenience.
2. Description of the Prior Art
With the advancement of entertainment and multimedia industry, television (TV) set has become one of the major leisure appliances for most people. TV set can not only present TV programs received from cable or radio channel, but also show images from DVD, Blu-Ray players, game consoles, computer systems and other devices. Also, in addition to display quality, TV set has obvious progress in functionality, such as video recording, picture in picture, memory card reading, automatic brightness adjustment, and so on.
However, to control the TV set, there are two typical ways, one is pressing buttons formed on a housing of the TV set, and the other is using a remote controller. Take the remote controller for example, when a user wants to control the TV set to execute a function, e.g. in-/decrease volume, the user can press a button corresponding to the function on the remote controller, such that the remote controller can emit a remote control signal. After receiving the remote control signal, the TV set can execute the related function. In general, a size of characters capable of being shown on the remote controller is limited; in other words, users having poor eyesight may encounter troubles as using the remote controller. For example, when a user with presbyopia wants to use the push-button remote controller, the user often needs to wear glasses to operate the remote controller, and takes off the glasses to see TV program, causing inconvenience each time the user wants to use the remote controller.
In addition, as the TV set includes more multimedia functions, functions to be controlled by the remote controller are becoming complicated, and not limited to channel or volume adjustment. In such a situation, the user, having poor eyesight or unfamiliar with new functions, often needs to overcome some difficulties, e.g. to know how to use some buttons or what the buttons mean. Meanwhile, because the user does not know how to use and may be afraid of using the buttons, the user maybe worry about damaging the TV set or changing parameters of the TV set if inadvertently touching the buttons, causing unnecessary stress when using the remote controller.
It is therefore an objective of the present invention to provide voice control device, voice control method and display device.
The present invention discloses a voice control device for a display device, which comprises a voice receiver for receiving a voice signal, a voice recognition unit coupled to the voice receiver for recognizing the voice signal to generate a recognition result, a function decision unit coupled to the voice recognition unit for selecting an operating function from a plurality of operating functions according to the recognition result, and an execution unit coupled to the function decision unit for controlling the display device to perform the operating function.
The present invention further discloses a voice control method for a display device, which comprises receiving a voice signal for recognizing the voice signal to generate a recognition result, selecting an operating function from a plurality of operating functions according to the recognition result, and controlling the display device to perform the operating function.
The present invention further discloses a display device, which comprises a screen, a processing circuit for receiving a video signal and displaying pictures corresponding to the video signal on the screen, and a voice control device. The voice control device comprises a voice receiver for receiving a voice signal, a voice recognition unit coupled to the voice receiver for recognizing the voice signal to generate a recognition result, a function decision unit coupled to the voice recognition unit for selecting an operating function from a plurality of operating functions according to the recognition result, and an execution unit coupled to the function decision unit for controlling the processing circuit to perform the operating function.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

In brief, when the voice receiver 200 receives a voice command from the user, the voice recognition unit 202 recognizes the contents thereof, and the function decision unit 204 determines the corresponding operating function, so as to control the processing circuit 102 to perform the required operating function via the control command CMD outputted by the execution unit 206. In other words, the user does not need to press any button formed on the housing of the display device 10 or use a remote control, while the user can control the processing circuit 102 to perform required operation functions. In such a situation, inconvenience or operating stress resulting from poor eyesight or unfamiliarity of new functions can be reduced. For example, a presbyopic user can orally control the display device 10 to execute a required operating function without repeating actions of wearing and taking off glasses, or concerning about wrong starts of some functions.
Note that, the voice control device 104 shown in
Furthermore, current television broadcast systems can provide program list functions; that is, an appended program list is transmitted with the broadcasting signals, which includes program information of all or part of TV channels, such as channel name, program title, program introduction, duration, classification, etc. In such a situation, as shown in
In addition, as shown in
By the same token, if the embodiments of
In addition, as mentioned above, the voice control device 104 can be formed inside the housing of the display device 10 as shown in
Moreover, to avoid the occurrence of erroneous control, a switch unit can be added, such as a button, to turn on or off the voice control device 104, to enhance convenience.
Furthermore, operations of the voice control device 104 can be summarized into a voice control procedure 60, as shown in
Step 600: Start.
Step 602: The voice receiver 200 receives a voice signal.
Step 604: The voice recognition unit 202 recognizes the voice signal, to generate a recognition result.
Step 606: The function decision unit 204 selects an operating function from a plurality of operating functions according to the recognition result.
Step 608: The execution unit 206 controls the display device 10 to perform the operating function.
Step 610: End.
The voice control procedure 60 represents the operations of the voice control device 104, and detail description can be referred in the above.
In the prior art, for users with poor eyesight, the limited size of characters shown on the remote controller can cause inconvenience, while for users unfamiliar to learn new functions, the complicated buttons of the remote controller may lead to stress for fear of erroneously triggering or damaging some functions. In comparison, the present invention uses voice recognition to determine an operating function required by the user, and controls the display device accordingly. Thus, the user does not need to operate any remote controller while controlling the display device, so as to enhance convenience, as well as reduce inconvenience and stress.
To summarize, the present invention controls the display device according to voices of a user, so as to greatly enhance utilization convenience.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention.
