Keyword Based Speaker Localization: Localizing a Target Speaker in a Multi-speaker Environment [PDF]
Interspeech 2018, 2018 Speaker localization is a hard task, especially in adverse environmental conditions involving reverberation and noise. In this work we introduce the new task of localizing the speaker who uttered a given keyword, e.g., the wake-up word of a distant-microphone voice command system, in the presence of overlapping speech.

A probabilistic framework for multiple speaker localization [PDF]
2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013 This paper presents a novel probabilistic framework for localizing multiple speakers with a microphone array. In this framework, the generalized cross correlation function (GCC) of each microphone pair is interpreted as a probability distribution of the time difference of arrival (TDOA) and subsequently approximated as a Gaussian mixture.

How to (Virtually) Train Your Speaker Localizer
INTERSPEECH 2023, 2023 Learning-based methods have become ubiquitous in speaker localization. Existing systems rely on simulated training sets for the lack of sufficiently large, diverse and annotated real datasets. Most room acoustics simulators used for this purpose rely on the image source method (ISM) because of its computational efficiency.

Local Features for Speaker Recognition [PDF]
, 2004 An approach combining a simple local representation method with a k-nearest neighbors-based direct voting scheme is proposed for speaker recognition. This approach rises computational problems that we effectively solved through an approximate fast k-nearest neighbors search technique.

3D Joint Speaker Position and Orientation Tracking with Particle Filters
Sensors, 2014 This paper addresses the problem of three-dimensional speaker orientation estimation in a smart-room environment equipped with microphone arrays. A Bayesian approach is proposed to jointly track the location and orientation of an active speaker. The main

Dynamically localizing multiple speakers based on the time-frequency domain
EURASIP Journal on Audio, Speech, and Music Processing, 2021 In this study, we present a deep neural network-based online multi-speaker localization algorithm based on a multi-microphone array. Following the W-disjoint orthogonality principle in the spectral domain, time-frequency (TF) bin is dominated by a single
