  2. 21. The Voice Source in Speech Communication - Production and Perception Experiments Involving Inverse Filtering and Synthesis

    Author : Christer Gobl; KTH; []
    Keywords : Voice source dynamics; glottal source parameters; source-filter interaction; voice quality; phonation; perception; affect; emotion; mood; attitude; paralinguistic; inverse filtering; knowledge-based; formant synthesis; LF model; fundamental frequency;

    Abstract : This thesis explores, through a number of production andperception studies, the nature of the voice source signal andhow it varies in spoken communication. Research is alsopresented that deals with the techniques and methodologies foranalysing and synthesising the voice source. READ MORE

  4. 22. Filter Bank Design for Subband Adaptive Filtering

    Author : Jan Mark de Haan; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Filter Bank Design; Subband Adaptive Filtering;

    Abstract : Adaptive filtering is an important subject in the field of signal processing and has numerous applications in fields such as speech processing and communications. Examples in speech processing include speech enhancement, echo- and interference- cancellation, and speech coding. READ MORE

  5. 23. Gesture as a Communication Strategy in Second Language Discourse : A Study of Learners of French and Swedish

    Author : Marianne Gullberg; Allmän språkvetenskap; []
    Keywords : HUMANIORA; HUMANITIES; second language acquisition; communication strategies; applied linguistics; gestures; Lingvistik; Linguistics; French; Swedish;

    Abstract : Gesture is always mentioned in descriptions of compensatory behaviour in second language discourse, yet it has never been adequately integrated into any theory of Communication Strategies (CSs). This study suggests a method for achieving such an integration. READ MORE

  6. 24. Applied Methods to Combat Noise in Human Communication

    Author : Benny Sällberg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Acoustic noise has a pronounced negative impact on human vocal communication and user comfort. Interfering noise that is transmitted between communicating users may not only disturb telephone conversation and supporting technical mechanisms (such as speech coders), but may also strain and eventually damage hearing and vocal organs of the users.

  7. 25. Acoustic Noise and Echo Cancelling : Microphone Array Methods and Applications

    Author : Mattias Dahl; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This Licentiate thesis is divided into three parts corresponding to three different papers. There is one research report, one conference paper and one submitted journal paper. All three parts deal with acoustic echo and/or noise cancelling problems when using adaptive microphone arrays. READ MORE
