Key Document

Description

This reference design uses multiple microphones, a beamforming algorithm, and other processes to extract clear speech and audio amidst noise and other clutter.  The rapid increase in applications that are used in noise-prone environments for voice activated digital assistants creates demand for systems that extract clear voice from noisy environments.  The reference design uses a microphone array and a sophisticated signal processing to extract clear audio from noisy environments.

Features
  • Single digital signal processor (DSP) SoC for audio preprocessing
  • Linear microphone board (LMB) with 4 microphones
  • Audio-preprocessing software
  • Hardware/software solution with modularized components to build an audio preprocessing solution for clear voice triggering and recognition
