Accurate Real-Time Estimation of 2-Dimensional Direction of Arrival using a 3-Microphone Array
Anton Kovalyov, Kashyap Patel, Issa Panahi
This paper presents a method for real-time estimation of 2-dimensional direction of arrival (2D-DOA) of one or more sound sources using a nonlinear array of three microphones. 2D-D…
DFSNet: A Steerable Neural Beamformer Invariant to Microphone Array Configuration for Real-Time, Low-Latency Speech Enhancement
Anton Kovalyov, Kashyap Patel, Issa Panahi
Invariance to microphone array configuration is a rare attribute in neural beamformers. Filter-and-sum (FS) methods in this class define the target signal with respect to a referen…
Closed-Form Solution for Scaling a Wireless Acoustic Sensor Network
Kashyap Patel, Anton Kovalyov, Issa Panahi
This study presents a closed-form solution for localizing and synchronizing an acoustic sensor node with respect to a Wireless Acoustic Sensor Network (WASN). The aim is to allow e…
UX-NET: Filter-and-Process-based Improved U-Net for Real-time Time-domain Audio Separation
Kashyap Patel, Anton Kovalyov, Issa Panahi
This study presents UX-Net, a time-domain audio separation network (TasNet) based on a modified U-Net architecture. The proposed UX-Net works in real-time and handles either single…
Noise dependent Super Gaussian-Coherence based dual microphone Speech Enhancement for hearing aid application using smartphone
Nikhil Shankar, Gautam S Bhat, Chandan K A Reddy +1
In this paper, the coherence between speech and noise signals is used to obtain a Speech Enhancement (SE) gain function, in combination with a Super Gaussian Joint Maximum a Poster…
An individualized super Gaussian single microphone Speech Enhancement for hearing aid users with smartphone as an assistive device
Chandan K A Reddy, Nikhil Shankar, Gautam Bhat +2
In this letter, we derive a new super Gaussian Joint Maximum a Posteriori based single microphone speech enhancement gain function. The developed Speech Enhancement method is imple…
