ReSpeaker Lite Voice Assistant Kit

USB Dual Microphone Array with XIAO ESP32S3

Powered by XMOS XU316 AI Sound and Audio chipset, it is a high-performance open source voice assistant development kit. The kit integrates the reSpeaker Lite dual-microphone array and a powerful XIAO ESP32S3 processor, offering exceptional voice recognition, noise reduction, and voice processing capabilities thanks to its onboard AI NLU algorithms. This kit provides firmware integration with Home Assistant via ESPHome, making it ideal for smart voice assistants and home automation applications.

Features

Pre-Soldered ESP32 Controller	A powerful XIAO ESP32S3 is pre-soldered via the I2S pins, offering a solderless experience for further development and integration.
Dual Microphone Array for Far-Field Voice Capture	The 2 high-performance digital microphones capture and extract far-field speech and voice (up to 3 meters), even in noisy environments, cancelling point noise using two-microphone input.
Onboard Audio Front-End Algorithms	Powered by the XMOS XU-316 AI sound and audio chip, featuring Natural Language Understanding algorithms for Interference Cancellation (IC), Acoustic Echo Cancellation (AEC), Noise Suppression, and Automatic Gain Control (AGC) for high-quality voice capture.
Embracing Open Source	Compatible with Arduino, PlatformIO, MicroPython, and CircuitPython for further development.
Compatible with Popular Voice Assistants	Enables building a natural language processor and connecting it to Home Assistant via ESPHome, Amazon Alexa Voice Service, Google Assistant, or Cloud Speech-to-Text, allowing voice interaction and commands.
Onboard RGB LED	Features a programmable WS2812 RGB LED supporting custom effects and providing a visual interface for applications.
