ReSpeaker Lite does not come with a MCU for data access and transmission (eg. a XIAO ESP32S3), and it is only for audio processing with XMOS's XU316. If you want to buy a complete Voice Assistant Kit, please visit here. The kit offers options for different ReSpeaker Lite models, Speaker, and acrylic enclosures.

  • 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 as it cancels point noise using two microphone input.
  • Onboard Audio front-end Algorithms:: Powered by XMOS XU-316 AI sound and audio chip, the kit includes Natural Language Understanding algorithms for Interference Cancellation (IC) , Acoustic Echo Cancellation, Noise Suppression, Voice-to-Noise Ratio (VNR), and Automatic Gain Control (AGC), enabling high quality voice capture.
  • Embracing Open Source: This board is compatible with popular hardware platforms (XIAO ESP32S3 (Sense), Adafruit QT Py) via I2S, and compatible with Raspberry Pi, PC via USB (Audio Class 2.0 (UAC2)).
  • Onboard RGB LED: The board features a programmable WS2812 RGB LED, supporting custom effects and offering a visual interface for your applications.
  • External Power Supply Support: this board supports external 5V power supply, which can be flexibly applied in different scenarios.
  • DFU for Custom Development: the board supports custom firmware update via DFU-Util.
