We propose a microphone array network that realizes ubiquitous sound acquisition. Several nodes with 16 microphones are connected to form a novel huge sound acquisition system, which carries out voice activity detection (VAD), sound source localization, and separation. The three operations are distributed among nodes. Using the distributed network, we achieve a low-traffic data-intensive array network...
We propose a microphone array network that realizes ubiquitous sound acquisition. Nodes with 16 microphones are connected to form a huge sound acquisition system that carries out VAD, sound source localization and separation. The three operations are distributed among nodes. The VAD is implemented to manage power consumption. Consequently, the system consumes little power when speech is not active...
