    Particle Filter Design Using Importance Sampling for Acoustic Source Localisation and Tracking in Reverberant Environments

    Sequential Monte Carlo methods have been recently proposed to deal with the problem of acoustic source localisation and tracking using an array of microphones. Previous implementations make use of the basic bo...

    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 th...

    Time Delay Estimation in Room Acoustic Environments: An Overview

    Time delay estimation has been a research topic of significant practical importance in many fields (radar, sonar, seismology, geophysics, ultrasonics, hands-free communications, etc.). It is a first stage that...

    Sector-Based Detection for Hands-Free Speech Enhancement in Cars

    Adaptation control of beamforming interference cancellation techniques is investigated for in-car speech acquisition. Two efficient adaptation control methods are proposed that avoid target cancellation. The "...

    Speaker Separation and Tracking System

    Replicating human hearing in electronics under the constraints of using only two microphones (even with more than two speakers) and the user carrying the device at all times (i.e., mobile device weighing less ...

    Kalman Filters for Time Delay of Arrival-Based Source Localization

    In this work, we propose an algorithm for acoustic source localization based on time delay of arrival (TDOA) estimation. In earlier work by other authors, an initial closed-form approximation was first used to...

    Dual-Channel Speech Enhancement by Superdirective Beamforming

    In this contribution, a dual-channel input-output speech enhancement system is introduced. The proposed algorithm is an adaptation of the well-known superdirective beamformer including postfiltering to the bin...
