Abstract
The invention provides a voice control method and a system of an intelligent television. An array type microphone is installed on the intelligent television, and an external sound signal is detected by the microphone. The external sound signal is transmitted to a digital audio signal processor DSP to analyze and process after the external sound signal passes through a pre-stage amplifier and an analog-to-digital conversion circuit. An I2S digital audio signal of an intelligent television machine core and the external sound signal received by the microphone are compared by the digital audio signal processor DSP, and a voice control signal is extracted. Then a true voice command is converted into a USB2.0 format control command, and voice control of the intelligent television is completed via the USB2.0 format control command. Experience of the voice control intelligent television is met for different users so that direct conversation operation between the users and the television is realized.
Description
Technical field

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
embodiment
As shown in Figure 1, system of the present invention comprises:
Array Microphone, it is arranged on intelligent television, and this Array Microphone is just as people's ear, for gathering the external voice signal of intelligent television.Array Microphone mainly consists of microphone 1, pre-amplifier 2, analog to digital conversion circuit 3, external voice signal is by microphone, pre-amplifier, analog to digital conversion circuit, be converted to the digital audio and video signals that can compare with I2S digital audio and video signals, in these digital audio and video signals, comprise for controlling the user speech instruction of television set, also comprise the spuious sound that sound of television that TV itself sends and TV environment of living in can not be controlled as instruction.
Audio decoder, it is the constituent components of intelligent television SOC chip 5.I2S digital audio and video signals after audio decoder decode had both been transferred to digital power amplifier 6, by loud speaker 7, played back, and the while is carried out the processing of audio frequency compare of analysis with the digital audio and video signals after analog-to-digital conversion that Array Microphone gathers again.
Digital audio signal processor DSP4, for the I2S digital audio and video signals of digital audio and video signals and intelligent television movement is compared, the background noise of filtering TV own, and extract useful voice control signal, then voice control signal is converted to the USB2.0 form control command that intelligent television SOC chip can be identified, the phonetic incepting module of post-processed and traditional intelligence TV is identical, and the voice that complete intelligent television by USB2.0 signal format are controlled.
Phonetic incepting module, the module that this comprises for traditional voice TV, the voice control signal of extracting for receiving digital audio signal processor DSP, and voice control signal is sent to intelligent television SOC chip;
Intelligent television SOC chip, for realizing the control to intelligent television according to voice control signal.
In addition, the I2C bus of intelligent television SOC chip 5 is connected with digital audio signal processor DSP4, passes on current intelligent television information volume.Digital audio signal processor DSP4 adjusts tv volume automatically according to the result of comparison, to reach best voice, controls environment, and correctly receives and passes on voice command to control television set.
As shown in Figure 2, the sound control method of intelligent television of the present invention comprises the following steps:
Step 1, digital audio signal processor DSP gather the external voice signal of intelligent television, and by it after amplifying, convert digital audio and video signals to;
Step 2, the I2S digital audio and video signals of digital audio and video signals and intelligent television movement is compared, and extract voice control signal, if extract voice control signal, start the phonetic function of intelligent television, digital audio signal processor DSP detects the size of television sound volume automatically simultaneously, if volume is greater than set point 40dB(as tv volume demonstration 20), provide instruction and automatically reduce tv volume to 40dB, to guarantee that environmental noise is lower in voice operating is used.
Step 3, by extracting voice control signal in step 2, convert USB2.0 form control command to, the voice that complete intelligent television by USB2.0 form control command are controlled.As, the built-in microphone of TV is said and activated word " Changhong TV ", start voice and control platform, there is little C voice assistant, television set during interconnection network, can not carry out local voice control, and little C correctly identifies predetermined instruction (as be switched to 25 channels, the simple instruction such as give great volume a bit) and carries out this operation, television set, in interconnection network situation, can carry out voice complex operations according to high in the clouds instruction (as searched for film, searching weather condition, traffic information etc.).
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, it should be pointed out that all any modifications of doing within the spirit and principles in the present invention, be equal to replacement and improvement etc., within all should being included in protection scope of the present invention.
