International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: R.A. Sukkar R. Younce Peng Zhang Tellabs Inc. Naperville IL USA
In new generation networks like 3G wireless and VoIP, a great deal of emphasis is put on transcoder-free operation (TrFO), where speech remains coded throughout the core network. Any network-based speech processing fu... 详细信息

International Conference on Innovations in Information Technology
作者: M. Sarwar Ehsan Gernot Kubin Signal Processing and Speech Communication Laboratory Graz University of Technology Austria
In many applications such as speech coding and PLC (packet loss concealment) methods, short-time stationarity of speech is assumed. In this paper, we introduce a new measure to model the short-time stationarity of spe... 详细信息
