For enhancing noisy signals, machine-learning based single-channel speech enhancement schemes exploit prior knowledge about typical speech spectral structures. To ensure a good generalization and to meet requirements in terms of computational complexity and memory consumption, certain methods restrict themselves to learning speech spectral envelopes. We refer to these approaches as machine-learning spectral envelope (MLSE)-based approaches. In this paper, we show by means of theoretical and…

Robust Speech Enhancement Using Statistical Signal Processing and Machine-Learning

The aim of this thesis is to increase the robustness of machine-learning (ML)-based and non-ML-based single-channel speech enhancement algorithms by exploiting synergies between both approaches by using super-Gaussian estimators to suppress the background noise even if the speech PSD is overestimated.

On Speech Enhancement Under PSD Uncertainty

A novel nonlinear clean speech estimator is derived that takes into account prior knowledge about the absolute value of typical speech PSDs and provides uncertainty-aware counterparts to a number of well-known conventionalclean speech estimators such as the Wiener filter and Ephraim and Malah's amplitude estimators.

Real-Time Speech Enhancement Algorithm Based on Attention LSTM

Because traditional single-channel speech enhancement algorithms are sensitive to the environment and perform poorly, a speech enhancement algorithm based on attention-gated long short-term memory (LSTM) is proposed, which maintains high real-time performance and fast convergence speed.

The extensive experimental investigation suggests that the MB-TCNs outperform the residual long short-term memory networks (ResLSTMs), temporal convolutional networks (TCNs), and the CNN networks that employ dense aggregations in terms of speech intelligibility and quality, while providing superior parameter efficiency.

The key to the method is its use of a harmonic structure to define the prior distribution of a spectral mask, which is used for both accurate noise estimation and attenuation and combines log mel-frequency feature enhancement with the above method to take advantage of low dimensionality.
