Application of speech recognition chip in smart voice remote control

With the development of science and technology, there are more and more smart home products and smart hardware products in the home. Many users have too many remote controls at home, such as TVs, air conditioners, fans, audio, TV boxes, etc., which they cannot find when they are actually used, so they need to be able to Remote controls for controlling different appliances. With the development of smart TVs and voice recognition technology, smart voice remote controls have gradually become a necessity for smart TVs and broadcast TV set-top boxes.
Geyuan Electronics provides intelligent voice remote control solution chips, which have the function of voice recognition to control TVs, set-top boxes and air conditioners, and are beautiful and comfortable.

GYT6802ABR1 is an ultra-low power offline speech recognition chip equipped with advanced voice activity detection, voiceprint recognition and automatic denoising neural network with efficient power management module, digital and analog voice signal input interface and its ARM Cortex-M0 Core, with GPIO, UART, SPI, I2C, I2S and other peripherals. It has offline speech recognition function with small size and low power consumption. Low-power sleep monitoring current is less than 100uA (data microphone)/150uA (analog microphone).

Generally, when you press the voice button on a smart voice remote control, the controller will send a HID code to notify the smart TV or set-top box to turn on the recognition function. At this time, the LED light of the controller keeps flashing or stays on, starts recording, and uploads the voice data to the smart TV or set-top box. After receiving the HID number, the smart TV or set-top box opens speech recognition software such as Google and starts to recognize the voice, recognizes the voice data as text, letters, etc., and then finds the corresponding program or opens the corresponding application by searching for keywords online.
