Data Compression Conference (DCC)
作者: Takehiro Moriya Yutaka Kamamoto Noboru Harada NTT Communication Science Laboratories Nippon Telegraph and Telephone Corporation Japan
Motivated by the rapid increase of VoIP services with G.711 for telephone speech, a new ITU-T recommendation, G.711.0 (frame-wise stateless lossless compression scheme for G.711 log PCM symbols), has been standardized... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: A. Tassy L. Miclet MATRA sa. Yvelines France Dpt. SYC UA CRNS 820 ENST Paris France
Vector Quantization has recently been used in the realization of a speaker-independent digit recognizer, based uniquely on the spectral content of the speech signal. On the other hand, the Hidden Markov Models proved ... 详细信息

International Conference on Neural Networks
作者: I.I. Ibrahim M.I. El-Adawy Electronics and Communications Department Faculty of Engineering and Technology Cairo Egypt Helwan University Cairo EG Dept. of Electron. & Commun. Helwan Univ. Cairo Egypt
A new technique for the determination of the LPC coefficients is introduced. In this method the LPC coefficients are shown to be the weighting factors of a simple neuron. This makes this technique suitable for a lot o... 详细信息
