Asilomar Conference on Signals, Systems & Computers
作者: Sourabh Ravindran C. Demirogulu D.V. Anderson School of Electrical and Computer Engineering Georgia Institute of Technology Atlanta GA USA School of Electrical and Computer Engineering Georgia Institute of Technology Atlanta GA
Mel-frequency cepstral coefficients (MFCC) have been shown to be very useful in tasks of speech recognition and are the preferred features in state of the art speech recognition systems. The author present features de... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: Ki-Seung Lee JeongSu Kim Department of Electronic Eng Konkuk University Seoul South Korea Human-Computer Interactive Laboratories Samsung Advanced Institute of Technology Gyeonggi South Korea
A method for the automatic segmentation of speech signals is described. The method is dedicated to the construction of a large database for a Text-To-Speech (TTS) synthesis system. The main issue of the work involves ... 详细信息

IEEE Workshop on Applications of Signal Processing to Audio and Acoustics
作者: S. Bharitkar C. Kyriakakis Integrated Media Systems Center University of Southern California Los Angeles CA
Typically, room equalization techniques do not focus on designing filters that equalize the room responses at perceptually relevant frequencies. Thus, by performing Bark warping of the room responses and using lower o... 详细信息

IEEE Workshop on Automatic Speech Recognition and Understanding
作者: M. Athineos D.P.W. Ellis LabROSA Department of Electrical Engineering Columbia University NY USA
Current speech recognition systems uniformly employ short-time spectral analysis, usually over windows of 10-30 ms, as the basis for their acoustic representations. Any detail below this timescale is lost, and even te... 详细信息

IEEE International Symposium on Signal Processing and Information Technology (ISSPIT)
作者: K. Funaki Computing and Networking Center University of Ryukyus Okinawa Japan
We have already proposed the ELS-based time-varying complex AR (TV-CAR) speech analysis based on forward LP as well as forward and backward LP in which the equation error is modeled by an AR model to whiten the error.... 详细信息
