Model-Based Bayesian Framework for Sound Source Using a Coprime Microphone Array
RPI ID: 2020-009-401 Innovation Summary: A Bayesian framework is introduced for enumerating sound sources and estimating their direction of arrival (DOA) in complex acoustic environments. The system models spatial audio data probabilistically to distinguish overlapping sources and infer their positions with high accuracy. It supports dynamic environments...

Multi-talker separation using 3-tuple coprime microphone arrays
RPI ID: 2020-011-401Innovation Summary:This invention presents a method for separating multiple overlapping speech signals using a 3-tuple coprime microphone array. The system processes subarray data to isolate individual talkers in noisy environments. It enhances speech recognition and audio clarity in real-time applications. The approach is computationally...
