ManyEars Description

Microphone array processing implementation for your Mac ManyEars (Microphone Array-Based Audition for Mobile Robots) implements microphone array processing to perform sound source localization, and also tracking and separation.Intelligent systems would benefit from being able to localize and track sound sources in real life settings. Such a capability can help localizing a person or an interesting event in the environment, and also provides enhanced processing for other capabilities such as speech recognition. To give this capability to a computing system, the challenge is not only to localize simultaneous sound sources, but to track them over time. The ManyEars project propose a robust sound source localization and tracking method using an array of eight microphones. The method is based on a frequency-domain implementation of a steered beamformer along with a particle filter-based tracking algorithm. Tests on a mobile robot show that the algorithm can localize and track in real-time multiple moving sources of different types over a range of 7 meters. These new capabilities allowed the robot to interact using more natural means with people in real life settings.
