Large-Area Microphone Array for Audio Source Separation Based on a Hybrid Architecture Exploiting Thin-Film Electronics and CMOS.
IEEE Journal of Solid-State Circuits(2016)
摘要
We present a system for reconstructing-independent voice commands from two simultaneous speakers, based on an array of spatially distributed microphones. It adopts a hybrid architecture, combining large-area electronics (LAE), which enables a physically expansive array (> 1m width), and a CMOS IC, which provides superior transistors for readout and signal processing. The array enables us to: 1) se...
