  1. 6. Speech enhancement for mobile communications

    Författare :Harald Gustafsson; []
    Nyckelord :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

  4. 8. Accounting for Individual Speaker Properties in Automatic Speech Recognition

    Författare :Daniel Elenius; Björn Granström; Mats Blomberg; Torjbjörn Svendsen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MAP; MLLR; VTLN; speaker characteristics; dynamic modeling; child; Information and language technology; Informations- och språkteknologi;

    Sammanfattning : In this work, speaker characteristic modeling has been applied in the fields of automatic speech recognition (ASR) and automatic speaker verification (ASV). In ASR, a key problem is that acoustic mismatch between training and test conditions degrade classification per- formance. LÄS MER

  5. 9. Hermeneutik och grammatik : Fenomenologiska undersökningar av språket som tal och teknik

    Författare :Andreas Widoff; Svenska; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; grammar; hermeneutics; phenomenology; structural linguistics; speech; technique; langue; parole;

    Sammanfattning : This thesis is a phenomenological investigation into the differences and similarities between language as speech and language as a technique. Speech is the practice of producing and understanding utterances. A technique is the organizing mechanism of speech, the structure that gives it a regular form. LÄS MER

  7. 10. Factors Governing Acoustical Comfort In Vehicle Compartments

    Författare :Oliver Jung; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driving Noise; Lombard Effect; Sound Quality; Psychoacoustics; Acoustical Comfort; Emotions; Vehicle Acoustics; Speech Communication; Cognition Psychology; Speech Quality;

    Sammanfattning : A pleasant interior sound field is an essential comfort criterion for vehicle occupants.The pleasantness is mainly influenced by a low overall sound pressurelevel. Further minimization of driving noise, however, is constricted on thelower end by physical limitations. LÄS MER
