Audio Preprocessing System Reference Design for Voice-Based Applications Using C5517
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.
