Real-Time Sound Localization System For Reverberant And Noisy Environment

A maximum a posteriori sound source localization in reverberant and noisy conditions

In this paper, a maximum a posteriori sound source localization (MAP-SSL) algorithm is proposed for reverberant and noisy conditions. It is derived by incorporating a sparse prior on the source location into the existing maximum likelihood sound source localization (ML-SSL) framework. The criterion in deriving the proposed MAP-SSL algorithm is similar to the criterion used in deriving the exist...

Binaural Sound Source Localization in Noisy Reverberant Environments Based on Equalization-Cancellation Theory

Robust Adaptive Time Delay Estimation for Speaker Localization in Noisy and Reverberant Acoustic Environments

Two adaptive algorithms are presented for robust time delay estimation (TDE) in acoustic environments with a large amount of background noise and reverberation. Recently, an adaptive eigenvalue decomposition (EVD) algorithm has been developed for TDE in highly reverberant acoustic environments. In this paper, we extend the adaptive EVD algorithm to noisy and reverberant acoustic environments, b...

Approaches for Time Difference of Arrival Estimation in a Noisy and Reverberant Environment

Determining the spatial position of a speaker finds a growing interest in video conference scenario where automated camera steering and tracking are required. As a preliminary step for the localization, microphone array can be used to extract the time difference of arrival (TDOA) of the speech signal. The direction of arrival of the speech signal is then determined by the relative time delay be...

Real-time sound source localization and separation for robot audition

Robot audition in the real world should cope with environment noises and reverberation and motor noises caused by the robot’s own movements. This paper presents the active direction-pass filter (ADPF) to separate sounds originating from the specified direction with a pair of microphones. The ADPF is implemented by hierarchical integration of visual and auditory processing with hypothetical reas...
