Audio preprocessing system reference design for speech-based applications

TIDEP-0088

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 assitants 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.

characteristic

● 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 with modularized components to build an audio pre-processing solution for clear voice triggering and recognition
