Audio Preprocessing System Reference Design for Voice-Based Applications

TIDEP-0099

Design files

Overview

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 TIDEP-0099 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 pre-processing
  • Circular Microphone Board (CMB) with 360 degree coverage of audio source
  • Audio pre-processing software
  • Hardware/software solution with modularized components to build an audio pre-processing solution for clear voice triggering and recognition
