Blind speech separation 作者：Shoji Makino,Te-Won Lee,Hiroshi Sawada 2007 This is the world's first edited book on independent component analysis (ICA)-based blind source separation (BSS) of convolutive mixtures of speech. This book brings together a s
An approach of speech inform ation hiding based on G．729 scheme，and ABS(Analysis—by—synthesis) algorithm of speech inform ation hiding and extracting， which form ing the theoretical basis for designing a secure speech com m unication system are prop
Abstract—In this paper, a new idea for speech information hiding using fractional cosine transform (FRCT) is proposed. We find in our analysis that the 3rd parameter of FRCT presents property of high frequency, then we put forward two methods for em
Abstract-Traditional speech information hiding methods have several disadvantages, for example, constant embedding amplitude, lower speech quality, higher bit error rate. A novel speech information hiding method based on Itakura-Saito measure and ps
Absimcf-User identification must be done in speech information hiding. To shorten the time of building link and exchanging protocol, this paper presents a technology for fast cross-identification. To enhance the security of communication, encryption
Abstract—The discrete cosine transform (DCT) has performance close to Karhunen-Loeve Transform (K-L Transform). In this paper, DCT is used for speech information hiding. Secret information is embedded by changing the parameters in DCT domain and ext
