A speech-and-speaker identification system: Feature extraction, description, and classification of speech-signal image
收藏 引用
IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS 2007年 第2期54卷 887-897页
作者: Saeed, Khalid Nammous, Mohammad Kheir Bialystok Tech Univ PL-15351 Bialystok Poland
This paper discusses a speech-and-speaker (SAS) identification system based on spoken Arabic digit recognition. The speech signals of the Arabic digits from zero to ten are processed graphically (the signal is treated... 详细信息

UNSTABLE COVARIANCE LPC SOLUTIONS FROM NONSTATIONARY SPEECH WAVEFORMS
收藏 引用
IEEE TRANSACTIONS ON ACOUSTICS SPEECH AND SIGNAL PROCESSING 1989年 第5期37卷 651-654页
作者: NG, CS MILENKOVIC, PH Department of Electrical and Computer Engineering University of Wisconsin Madison Madison WI USA
linear predictive coding (LPC) analysis of speech is made using a stationary model while parts of speech such as stop consonants are highly nonstationary. An asymptotic analysis is made of the stability of the LPC mod... 详细信息

EFFICIENT ADAPTIVE VECTOR QUANTIZATION OF LPC PARAMETERS
收藏 引用
IEEE TRANSACTIONS ON SPEECH AND AUDIO PROCESSING 1995年 第4期3卷 314-317页
作者: FERRERBALLESTER, MA FIGUEIRASVIDAL, AR ETSI Telecomunicacóin Universidad de Las Palmas de Gran Canaria Las Palmas Spain GPSS-DSSR ETSI Telecomunicación Universidad Politécnica de Madrid Madrid Spain
This correspondence presents a new two-stage adaptive vector quantizer of LSF parameters in LPC speech coding. The first codebook is adapted by a partition-delete operation, whereas the code-vectors of the second code... 详细信息
