  1. 1. Knowledge-based speech enhancement

    Author : Sriram Srinivasan; Bastiaan Kleijn; Rainer Martin; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speech enhancement; noise reduction; linear predictive coe±cients; autoregressive; codebooks; maximum-likelihood; Bayesian; nonstationary noise; blind source separation.; Telecommunication; Telekommunikation;

    Abstract : Speech is a fundamental means of human communication. In the last several decades, much effort has been devoted to the efficient transmission and storage of speech signals. With advances in technology making mobile communication ubiquitous, communications anywhere has become a reality. READ MORE

  2. 2. Speech enhancement for mobile communications

    Author : Harald Gustafsson; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speech enhancement; spectral subtraction;

    Abstract : Three major applications of speech enhancement have been studied: noise reduction for mobile telephone handsfree accessories, noise reduction for handheld mobile telephones, and short delay noise reduction for frame-less telephone systems. During conversation, both hearing and speaking adapt to the background noise in a noisy environment. READ MORE

    Author : Nils Westerlund; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Speech Enhancement; Active Noise Control;

    Abstract : In our daily life noise is almost constantly present. At the same time our need to communicate reliably has probably never been this great. Surrounding noise impairs our ability to communicate by speech and causes the users of a speech communication system to strain both their hearing and their voices. READ MORE

  5. 5. Speech Signal Extraction : A Multichannel Approach

    Author : Nedelko Grbic; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Speech Enhancement; Blind signal separation; Echo control; Adaptive systems;

    Abstract : In speech signal extraction the aim is to extract human speech in a physical environment by using microphones. In any real world environment there are many disturbance sources that cause unwanted sound pressure, which in turn may degrade the comprehension of the speech at the microphones. READ MORE
