A two-stage speaker extraction algorithm under adverse acoustic conditions using a single-microphone
Aviad Eisenberg, Sharon Gannot, Shlomo E. Chazan
In this work, we present a two-stage method for speaker extraction under reverberant and noisy conditions. Given a reference signal of the desired speaker, the clean, but the still…
Don't Be So Sure! Boosting ASR Decoding via Confidence Relaxation
Tomer Wullach, Shlomo E. Chazan
Automatic Speech Recognition (ASR) systems frequently use a search-based decoding strategy aiming to find the best attainable transcript by considering multiple candidates. One pro…
Magnitude or Phase? A Two Stage Algorithm for Dereverberation
Ayal Schwartz, Sharon Gannot, Shlomo E. Chazan
In this work we present a new single-microphone speech dereverberation algorithm. First, a performance analysis is presented to interpret that algorithms focused on improving solel…
Enhancing Speech Recognition Decoding via Layer Aggregation
Tomer Wullach, Shlomo E. Chazan
Recently proposed speech recognition systems are designed to predict using representations generated by their top layers, employing greedy decoding which isolates each timestep fro…
CNN self-attention voice activity detector
Amit Sofer, Shlomo E. Chazan
In this work we present a novel single-channel Voice Activity Detector (VAD) approach. We utilize a Convolutional Neural Network (CNN) which exploits the spatial information of the…
Single microphone speaker extraction using unified time-frequency Siamese-Unet
Aviad Eisenberg, Sharon Gannot, Shlomo E. Chazan
In this paper we present a unified time-frequency method for speaker extraction in clean and noisy conditions. Given a mixed signal, along with a reference signal, the common appro…
