  1. 1. Knowledge-based speech enhancement

    Författare :Sriram Srinivasan; Bastiaan Kleijn; Rainer Martin; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  2. 2. Speech enhancement for mobile communications

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

    Sammanfattning : 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. LÄS MER

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

    Sammanfattning : 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. LÄS MER
