A far-field reference solution for the Alexa Voice Service

DSPG HDClear 3-Mic
Development Kit for Amazon AVS

Price $249.00

The DSP Group HDClear 3-Mic Development Kit for Amazon AVS enables low-power wake-on-voice operation and far-field voice recognition performance with only three microphones. It is well suited for a broad range of applications, including the development of battery-powered devices such as portable smart speakers, IoT gadgets, and smart home devices.

The solution includes the audio-centric DBMD5 processor that incorporates the DSP, HDClear voice enhancement signal processing algorithms, and Voice Activity Detector with three power operating modes (low power 1-mic voice trigger, 3-mic noise reduction, and 3-mic barge-in). This optimized architecture makes it possible for battery-powered devices to continuously monitor voice activity and detect the “Alexa” wake word while minimizing system-level power consumption. Features include:

  • A reference client for Raspberry Pi 3 built using the AVS Device SDK
  • HDClear algorithms for beamforming, noise reduction, and Acoustic Echo Cancellation
  • The HDClear DSP Board with dual-core DBMD5 processor
