Codebook-based Bayesian speech enhancement for nonstationary environments
收藏 引用
IEEE TRANSACTIONS ON AUDIO SPEECH AND LANGUAGE PROCESSING 2007年 第2期15卷 441-452页
作者: Srinivasan, Sriram Samuelsson, Jonas Kleijn, W. Bastiaan Royal Inst Technol Dept Signals Sensors & Syst SE-10044 Stockholm Sweden
In this paper, we propose a Bayesian minimum mean squared error approach for the joint estimation of the short-term predictor parameters of speech and noise, from the noisy observation. We use trained codebooks of spe... 详细信息

Noncausal all-pole modeling of voiced speech
收藏 引用
IEEE TRANSACTIONS ON SPEECH AND AUDIO PROCESSING 1997年 第1期5卷 1-10页
作者: Gardner, WR Rao, BD QUALCOMM INC SAN DIEGO CA USA
This paper introduces noncausal all-pole models that are capable of efficiently capturing both the magnitude and phase information of voiced speech, It is shown that noncausal all-pole filter models are better able to... 详细信息

EXCITATION-SYNCHRONOUS MODELING OF VOICED SPEECH
收藏 引用
IEEE TRANSACTIONS ON ACOUSTICS SPEECH AND SIGNAL PROCESSING 1987年 第9期35卷 1241-1249页
作者: PARTHASARATHY, S TUFTS, DW UNIV RHODE ISL DEPT ELECT ENGN KINGSTON RI 02881 USA
A new modeling technique for voiced speech is introduced. Salient features are detailed modeling of speech waveforms and the use of improved parameter estimation techniques. The ideas of pitch-synchronous analysis are... 详细信息

Resolution Warped Spectral Representation for Low-Delay and Low-Bit-Rate Audio Coder
收藏 引用
IEEE-ACM TRANSACTIONS ON AUDIO SPEECH AND LANGUAGE PROCESSING 2015年 第2期23卷 288-299页
作者: Sugiura, Ryosuke Kamamoto, Yutaka Harada, Noboru Kameoka, Hirokazu Moriya, Takehiro Univ Tokyo Grad Sch Informat Sci & Technol Tokyo 1138656 Japan NTT Corp NTT Commun Sci Labs Atsugi Kanagawa 2430198 Japan
We have devised a high-quality frequency-domain audio coder based on the state-of-the-art monaural wide-band coder aiming at its use in low-delay and low-bit-rate conditions. The coder efficiently represents frequency... 详细信息
