Intelligent voice-controlled lamps apply voice recognition chip GYT6811

Geyuan Electronics introduces a voice recognition chip that is very suitable for smart voice-controlled lighting applications. GYT6811 is an ultra-low-power offline intelligent speech recognition chip that integrates advanced voice activity detection (VAD), voiceprint recognition, automatic denoising neural network, and has an efficient power management module, digital and analog voice signal input interfaces And ARM Cortex-M0 core, and equipped with GPIO, UART, SPI, I2C, I2S and other on-chip peripherals. In scenarios such as Bluetooth headsets, smart remote controls, and smart homes, GYT6811 can realize offline speech recognition functions with a smaller size and extremely low power consumption.

GYT6811 features and advantages
