Microphone Array Speaker Localizers Using Spatial-Temporal Information
A dual-step approach for speaker localization based on a microphone array is addressed in this paper. In the first stage, which is not the main concern of this paper, the time difference between arrivals of the speech signal at each pair of microphones is estimated. These readings are combined in the second stage to obtain the source location. In this paper, we focus on the second stage of the ...
متن کاملRobust Neuro-Fuzzy Speaker Localization Using a Circular Microphone Array
A major application area of microphone array processing is the localization of sound sources, mainly of speaking persons. In contrast to most state-of-the-art approaches that are based on correlation measures, we propose a neurologically inspired system that generalizes findings about human spatial hearing to the multi-channel case. It mimics the processing in the human cochlea and the auditory...
متن کاملMicrophone array response to speaker movements
Matched ltering and adaptive beamforming are both necessary for e cient speech dereverberation and noise reduction by microphone arrays. This can be achieved by the identi cation of impulse responses. In this contribution, we show that adaptive microphone arrays are sensitive to identi cation errors of impulse responses, particularly due to speaker movements. We prove that adjusted matchedlteri...
متن کاملSpeaker Localization Exploiting Spatial-temporal Information
Determining the spatial position of a speaker finds a growing interest in video conference scenario where automated camera steering and tracking are required. Speaker localization can be achieved with a dual step approach. In the preliminary stage microphone array is used to extract the time difference of arrival (TDOA) of the speech signal. These readings are then used by the second stage for ...
متن کاملReal-Time Speaker Verification with a Microphone Array
Real-time speaker verification, with speech acquired using the NIST Mk-III microphone array and an autodirective beamforming algorithm, is demonstrated. The software and hardware backbone of the demonstration is the NIST Smart Flow System and Mk-III Array, both developed by National Institute of Standards and Technology in support of multimodal research communities. A microphone array acquires ...
