Television set with speech identifying function
Technical field
The utility model relates to a kind of television set, in particular, relates to a kind of television set with speech identifying function.
Background technology
Present television set mainly is to adopt manually control, by manual control button input various command, makes that television set can carry out that channel is better according to user's requirement, volume adjusting etc.But because TV functions from strength to strength, the number of keys on remote controller or the television set increases gradually, increased the input of producing, and, for special populations such as blind person, hand are handicapped, maybe can not control television set owing to can not see the button on the remote controller, use very inconvenient with hand.
The utility model content
The utility model is in order to overcome weak point of the prior art, to provide a kind of control that can carry out the television set operation by voice, television set easy to use.
The utility model is achieved through the following technical solutions:
A kind of television set with speech identifying function, it is characterized in that, comprise speech processor, encoding and decoding speech module, speech memory, asynchronous communication serial port module, microphone, described speech processor is connected with described asynchronous communication serial port module, encoding and decoding speech module, speech memory respectively, the audio signal input end of described encoding and decoding speech module is connected with described microphone, and described asynchronous communication serial port module is connected with the master controller of television set.
The utlity model has following technique effect:
Television set of the present utility model has speech identifying function, changed the interactive model of people and computer, people only need open one's mouth, just can open or close program, change working interface, make people's both hands obtain liberation, everyone can both be operated and appliance computer, use easily for blind person and the handicapped people of hand especially.
Description of drawings
Fig. 1 has the hardware configuration schematic diagram of the television set of language identification function for the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments this patent is elaborated.
Fig. 1 has the hardware configuration schematic diagram of the television set of language identification function for the utility model, comprise speech processor, encoding and decoding speech module, speech memory, asynchronous communication serial port module, microphone, described speech processor is connected with described asynchronous communication serial port module, encoding and decoding speech module, speech memory respectively, the audio signal input end of described encoding and decoding speech module is connected with described microphone, and described asynchronous communication serial port module is connected with the master controller of television set.
Wherein, speech processor is mainly finished the control that reaches other modules is handled in the identification of the discrete voice signal after the sampling, preferably adopts the DSP module.Encoding and decoding speech module special disposal audio signal is finished the voice signal sampling and the analog-to-digital conversion of input, and can be become analog signal to be exported by audio output port the conversion of signals after the speech processor processing.The asynchronous communication serial port module realizes that speech processor transmits data to television set, mainly finishes the parallel/serial conversion of level conversion data transmission and the functions such as baud rate setting of serial transmission, finishes communication function.
In software program, increase " speech recognition " menu, and set whether need the opening voice recognition function when seeing TV by software program.When the user wants to open this function when seeing TV, can enter menu option by remote controller, on television screen, eject OSD and " whether open ", after the user presses acknowledgement key, television set enters speech recognition and opens the selection picture, sets according to the personal like.When needs are operated television set, the sound that the people sends is input to the encoding and decoding speech module by microphone, by the encoding and decoding speech module voice signal is sampled and analog-to-digital conversion, deliver to the identification processing that speech processor carries out the discrete voice signal, signal after speech processor is handled is delivered to the master controller of television set by the asynchronous communication serial port module, the master controller of television set is finished function corresponding according to the signal after discerning, and people just can come RTV remote television by language according to the demand of oneself like this.
