The TV with audio exports audio and program output audio compares after eliminating, and is parsed to voice input audio；
Described control unit is connected with the voice recognition unit, executes the instruction after the voice input audio parsing.
Further, it is additionally provided with audio output interface.
Further, the audio output interface is connected with the audio output unit.
Further, the TV is connected with the audio output interface and the voice recognition unit respectively, receives institute
The output audio of program all the way of set-top box is stated, and the TV is exported into audio transmission to the voice recognition unit.
Further, the audio output interface is the ports HDMI or AV.
Further, the audio output unit, voice recognition unit and control unit are correspondingly provided with processing chip.
In another aspect of this invention, it is proposed that a kind of dry using foregoing set-top box removal television broadcast sounds source
The method disturbed, including：
By audio output unit, the program output audio of the set-top box is divided into identical two-way and is transmitted separately to voice knowledge
Other unit and TV；
Voice recognition unit receives TV output audio and voice inputs audio；
After the TV of identical audio is exported audio and program output audio comparison elimination by voice recognition unit, to institute's predicate
Sound input audio is parsed；
Control unit executes the instruction after the voice input audio parsing.
Further, program output audio output interface of the audio through the set-top box of the set-top box is transmitted to electricity
Depending on.
Beneficial effects of the present invention include at least：The present invention effectively excludes interference of the program audio to speech recognition, into
And the discrimination of voice input is improved, and set-top box can also save the input of other voices directly as voice acceptance terminal
Equipment.
Description of the drawings
Fig. 1 is set up box structure schematic diagram of the present invention.
Fig. 2 is the method for the present invention flow chart.
Specific implementation mode
The present invention provides a kind of set-top box and its methods of removal television broadcast sounds source interference, solve the prior art
In when watching TV programme using the interference of television audio caused by speech voice input function the problem of, further promote voice
The correct recognition rata of input.
Technical solution in the embodiment of the present invention is in order to solve the above technical problems, general thought is as follows：
By the way that the program output audio of set-top box is divided into identical two-way while inputing to voice recognition chip and TV, and
And it can effectively exclude the output audio pair of TV programme using semantic and language consistency caused by two kinds of audios
The interference of user speech identification, and then improve the discrimination of voice input.
In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper
Technical solution is stated to be described in detail.
Embodiment one：
According to an embodiment of the invention, Fig. 1 is set up box structure schematic diagram of the present invention, shown referring to Fig.1, of the present invention one
The set-top box of kind removal television broadcast sounds source interference, is internally provided with audio output unit, voice recognition unit and control
Unit, wherein the audio output unit, voice recognition unit and control unit are correspondingly provided with processing chip, it is possible to understand that
For：Audio output chip, voice recognition chip and control chip.
The audio output chip is connected with the voice recognition chip and TV respectively, and the program of the set-top box is defeated
Go out audio 1 and be divided into identical two-way to be transmitted separately to the voice recognition chip and TV.
The voice recognition chip is for receiving TV output audio 3, voice input audio 4 and program output audio
1, after the TV of identical audio is exported audio 3 and the program output comparison elimination of audio 1, audio 4 is inputted to the voice
It is parsed.
The control chip is connected with the voice recognition chip, executes the instruction 5 after the voice input audio parsing
Carry out subsequent operation.
The set-top box of embodiment one of the present invention further includes：Audio output interface, with the audio output chip phase
Even, the TV is connected with the audio output interface and the voice recognition chip respectively, on the one hand receives the set-top box
Program all the way export audio 2, the TV is on the other hand exported into audio transmission 3 to the voice recognition chip simultaneously.
Other embodiments according to the present invention, audio output interface of the present invention is the ports HDMI or AV or other are normal
Advise port.
Embodiment two：
In another aspect of this invention, it is proposed that a kind of to remove the interference of television broadcast sounds source using foregoing set-top box
Method, according to an embodiment of the invention, Fig. 2 are that the method for the present invention flow chart specifically includes referring to Fig.1 with shown in 2：
S01：By audio output chip, the program output audio 1 of the set-top box is divided into identical two-way and is transmitted separately to
The audio output interface of voice recognition chip and set-top box,
The program all the way of the audio output interface external tv, the set-top box exports audio 2 through the audio output interface
It is transmitted to TV；
S02：Voice recognition chip receives TV output audio 3 and voice input audio 4 simultaneously, at this point, voice recognition chip connects
Receive the audio 1 of input, 3,4, since the audio that audio 1,3 is inputted is completely the same；
S03：The TV of identical audio is exported audio to voice recognition chip and program output audio is identified comparison and disappears
After removing, the audio 4 of only remaining input carries out resolving to instruction 5 as the audio that actual speech inputs；
S04：The instruction that control chip executes after the voice input audio parsing carries out subsequent operation.
Since the inside of set-top box is for the audio of actual program（I.e. program exports audio 1）It has been input to voice knowledge
In other chip, when external electrical regards generated audio sound（I.e. TV exports audio 3）After collecting again in speech chip, by
In the consistency of the semanteme and language of two audios, it is possible to exclude television audio completely and be done for what user speech inputted
It disturbs.
In conclusion the application programs of set-top box audio output and the consistency of television audio output, it can be effective
It excludes when watching TV programme, using the interference of television audio caused by speech voice input function, it is defeated further to promote voice
The correct recognition rata entered.
