Problems solved by technology

Based on the above problems, wireless transmission has become an ideal solution. Wireless transmission can get rid of the limitation of data lines, so as to solve the limitation of user voice interaction distance. At present, there are many ways of wireless transmission, such as ZigBee, Bluetooth or WiFI, etc., but the above There are certain limitations in the method, and the most important bottleneck is that the 2.4GHz frequency band currently used by each device is becoming more and more crowded, and it receives more and more interference, especially for smart TVs, which have many integrated 2.4GHz modules, such as WiFi And Bluetooth, it is easy to cause interference to the voice signal and affect the voice recognition effect
More importantly, in order to solve the mutual interference problem, 2.4GHz wireless transmission technology mostly adopts frequency hopping technology. Undoubtedly a fatal flaw for speech recognition
Based on the above problems, it can be seen that the current smart TV far-field voice recognition system has limitations and cannot meet the needs of TV far-field voice recognition

Abstract

The invention discloses a television distant field voice recognition system and a method thereof based on a 5.8GHz wireless transmission. The microphone array module is used for collecting mixed fieldvoice data; the DSP processing module filters out sound data sent by the television end to receive voice commands through a preset algorithm; the 5.8 GHz radio frequency module is configured to perform modulation and demodulation on the voice command, and the demodulated voice command is output to the television SOC system; the television SOC system is used for comparing the voice command with the background voice database to generate an operation instruction, thereby controlling the television APP to complete the corresponding voice operation. Compared with the wireless technology of the 2.4GHz frequency band carrier, the system has wider transmission bandwidth by adopting the 5.8 GHz band carrier to transmit voice data. The system has the advantages of stronger anti-interference capacity, no extra transmission delay and better human-computer interaction. The system can better meet the needs of distant field voice recognition and data transmission of television.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a system and method for far-field speech recognition based on 5.8GHz wireless transmission television. Background technique [0002] With the development of smart TV technology, human-computer interaction methods are becoming more and more diversified. At present, the application of voice recognition technology in TVs is becoming more and more extensive. Voice technology can allow customers to operate TVs more conveniently and quickly. [0003] At present, the voice recognition function of most smart TVs requires the user to be very close to the TV, or even to interact with the TV to correctly recognize user instructions. As the distance increases, the recognition rate also decreases. Based on the above problems, wireless transmission has become an ideal solution. Wireless transmission can get rid of the limitation of data lines, so as to solve the limitation of user voice in...
