The Importance of Spatial and Spectral Information in Multiple Speaker Tracking

ICASSP 2025accepted

Multi-speaker localization and tracking using microphone array recording is of importance in a wide range of applications. One of the challenges with multi-speaker tracking is to associate direction estimates with the correct speaker. Most existing association approaches rely on spatial or spectral…

Ambisonics Networks - The Effect of Radial Functions Regularization

ICASSP 2024accepted

Ambisonics, a popular format of spatial audio, is the spherical harmonic (SH) representation of the plane wave density function of a sound field. Many algorithms operate in the SH domain and utilize the Ambisonics as their input signal. The process of encoding Ambisonics from a spherical microphone…

Subspace Hybrid Beamforming for Head-Worn Microphone Arrays

ICASSP 2023accepted

A two-stage multi-channel speech enhancement method is proposed which consists of a novel adaptive beamformer, Hybrid Minimum Variance Distortionless Response (MVDR), Isotropic-MVDR (Iso), and a novel multi-channel spectral Principal Components Analysis (PCA) denoising. In the first stage, the Hybri…

Enhanced robot audition by dynamic acoustic sensing in moving humanoids

ICASSP 2015accepted

Auditory systems of humanoid robots usually acquire the surrounding sound field by means of microphone arrays. These arrays can undergo motion related to the robot's activity. The conventional approach to dealing with this motion is to stop the robot during sound acquisition. This approach avoids ch…
