Grove - Offline Voice Recognition Module

This is a low-power pure-offline voice recognition module with less than 100ms identification time and 150 pre-programmed commands. It uses the US516P6 voice chip with a 32-bit RSIC architecture core, DSP instruction set, and FPU arithmetic unit. Ideal for various smart devices like smart home appliances, toys, and lamps that require voice control.

PRODUCT DETAILS

Features

  • Rich Peripherals: Support 1 analog Mic input and 4 digital Mic inputs and dual-channel DAC outputs;
  • Wide Voltage Support: on-board voltage conversion circuitry, compatible with 3.3V/5V power supply;
  • Smart Detection: Built-in POR (Power on Reset), Low Voltage Detection and Watchdog;
  • Grove Interface: full-duplex UART up to 3Mbps.

Description

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!
