Multi-Task Learning U-Net for Single-Channel Speech Enhancement and Mask-Based Voice Activity Detection

Applied Sciences, 2020
In this paper, a multi-task learning U-shaped neural network (MTU-Net) is proposed and applied to single-channel speech enhancement (SE). The proposed MTU-based SE method estimates an ideal binary mask (IBM) or an ideal ratio mask (IRM) by extending the ...

Acoustic echo cancellation based on two‐stage BLSTM

Electronics Letters, Volume 60, Issue 7, April 2024.
A two‐stage bidirectional long short term memory (TS‐BLSTM) framework, incorporating multi‐head self‐attention mechanisms after each BLSTM block, is introduced. The BLSTM blocks are utilized to aggregate magnitude spectrogram information, modelling both time and frequency dependencies.

EVALUATION OF SPEECH ENHANCEMENT IN NOISY CONDITIONS USING A SPECTRAL SUBTRACTION AND LINEAR PREDICTION COMBINATION [PDF]

ICTACT Journal on Communication Technology, 2012
Improving quality and intelligibility of speech signals in mobile devices has been studied with great interest in the past. Speech information in communication channels is usually corrupted by additive acoustic noise, reverberation or channel noise. This

Speech Enhancement Using Joint DNN‐NMF Model Learned with Multi‐Objective Frequency Differential Spectrum Loss Function

IET Signal Processing, Volume 2024, Issue 1, 2024.
We propose a multi‐objective joint model of non‐negative matrix factorization (NMF) and deep neural network (DNN) with a new loss function for speech enhancement. The proposed loss function (LMOFD) is a weighted combination of a frequency differential spectrum mean squared error (MSE)‐based loss function (LFD) and a multi‐objective MSE loss function ...
