360° Omnidirectional Digital Human Interaction Microphone Array

360° Omnidirectional Digital Human Interaction Microphone Array

Product Overview

The AMM-GY6335-Pro is a high-performance MEMS microphone array voice front-end solution designed for advanced human–machine interaction and digital human systems.
Powered by a quad-core Cortex-A35 CPU (up to 1.3 GHz), this module integrates iFLYTEK’s industry-leading speech algorithms, enabling precise voice activation, directional beamforming, and noise suppression for far-field pickup.

By leveraging the spatial filtering capabilities of the microphone array, the system can accurately locate the direction of the wake word, form a targeted audio beam, and effectively suppress off-axis noise.
Additionally, the AMM-GY6335-Pro features a high-performance echo cancellation engine, optimizing voice and semantic recognition accuracy — making it an ideal front-end platform for integrated voice interaction terminals.
