Neural networks based EEG-Speech Models
Pengfei Sun, Jun Qin
In this paper, we propose an end-to-end neural network (NN) based EEG-speech (NES) modeling framework, in which three network structures are developed to map imagined EEG signals t…
Enhanced Factored Three-Way Restricted Boltzmann Machines for Speech Detection
Pengfei Sun, Jun Qin
In this letter, we propose enhanced factored three way restricted Boltzmann machines (EFTW-RBMs) for speech detection. The proposed model incorporates conditional feature learning…
Speech Enhancement via Two-Stage Dual Tree Complex Wavelet Packet Transform with a Speech Presence Probability Estimator
Pengfei Sun, Jun Qin
In this paper, a two-stage dual tree complex wavelet packet transform (DTCWPT) based speech enhancement algorithm has been proposed, in which a speech presence probability (SPP) es…
Low Rank and Sparsity Analysis Applied to Speech Enhancement via Online Estimated Dictionary
Pengfei Sun, Jun Qin
We propose an online estimated dictionary based single channel speech enhancement algorithm, which focuses on low rank and sparse matrix decomposition. In this proposed algorithm,…
Semi-supervised Speech Enhancement in Envelop and Details Subspaces
Pengfei Sun, Jun Qin
In this study, we propose a modulation decoupling based single channel speech enhancement subspace framework, in which the spectrogram of noisy speech is decoupled as the product o…
