Detecting pitch of singing voice in polyphonic audio
Yipeng Li,DeLiang Wang +1 more
TL;DR: A robust algorithm to detect the pitch of a singing voice in polyphonic audio is proposed and an HMM is employed to integrate the periodicity information across frequency channels and time frames.
Journal ArticleDOI
A CASA-Based System for Long-Term SNR Estimation
Arun Narayanan,DeLiang Wang +1 more
TL;DR: Results indicate that both global and subband SNR estimates are superior to those of existing methods, especially at low SNR conditions.
Proceedings ArticleDOI
Robust speaker recognition based on DNN/i-vectors and speech separation
Jorge Chang,DeLiang Wang +1 more
TL;DR: This study investigates a phonetically-aware i-vector system in noisy conditions and proposes a front-end to tackle the noise problem by performing speech separation and examines its performance for both verification and identification tasks.
Proceedings ArticleDOI
Late Reverberation Suppression Using Recurrent Neural Networks with Long Short-Term Memory
TL;DR: A supervised speech dereverberation algorithm that models late reverberation using a recurrent neural network (RNN) with long short-term memory (LSTM) to take advantage of LSTM's ability to capture a long history can be effectively removed by the proposed approach.
Proceedings ArticleDOI
Integrating Spectral and Spatial Features for Multi-Channel Speaker Separation.
Zhong-Qiu Wang,DeLiang Wang +1 more
TL;DR: This paper tightly integrates spectral and spatial information for deep learning based multi-channel speaker separation by localizing individual speakers so that an enhancement network can be used to separate the speaker from an estimated direction and with specific spectral characteristics.
