Online Voice recognition modules require a reliable internet connection to generate responses and are not independent of the Microcontroller/Processor controlling them. While one can create an offline voice recognition module using a compatible processor like RaspberryPi, and train a custom neural network to do this, it is not feasible for battery-operated edge devices

This Grove-Offline Voice Recognition Module is a truly offline voice recognition module with 150 pre-programmed voice commands, which can be communicated through UART. It features connections for the speaker and microphone, along with indicator LEDs. The power supply to the module is ESD-protected, adding more safety to the module. It is a perfect low-cost solution for adding voice control to your IoT projects!

Features

FFT Accelerator: Supports up to 1024 points of complex FFT/IFFT operations or 2048 points of real FFT/IFFI;
Rich Peripherals: Support 1 analog Mic input and 4 digital Mic inputs and dual-channel DAC outputs;
Built-in voltage conversion:Supports 3.6V to 5V range power inputs and built-in 5V to 3.3V and 3.3V to 1.2V LDOs to power the chip;
Smart Detection: Built-in POR (Power on Reset), Low Voltage Detection and Watchdog;
Rich Interface: 1 full-duplex UART up to 3Mbps and supports SPI, I2C, ADC, and PWM interfaces.
