  1. 1. Hidden Markov models : Identification, control and inverse filtering

    Author : Robert Mattila; Bo Wahlberg; Eric Moulines; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hidden markov models; system identification; method of moments; inverse filtering; abdominal aortic aneurysm; medical; markov decision process; structure; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The hidden Markov model (HMM) is one of the workhorse tools in, for example, statistical signal processing and machine learning. It has found applications in a vast number of fields, ranging all the way from bioscience to speech recognition to modeling of user interactions in social networks. READ MORE

  2. 2. Hidden Markov Models: Identification, Inverse Filtering and Applications

    Author : Robert Mattila; Bo Wahlberg; Cristian R. Rojas; John Lygeros; Jan H. van Schuppen; Tobias Rydén; Ayca Özcelikkale; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hidden Markov models; HMM; inverse filtering; identification; estimation; method of moments; counter-adversarial autonomous systems; adversarial signal processing; belief estimation; abdominal aortic aneurysm; medical; Electrical Engineering; Elektro- och systemteknik;

    Abstract : A hidden Markov model (HMM) comprises a state with Markovian dynamics that is hidden in the sense that it can only be observed via a noisy sensor. This thesis considers three themes in relation to HMMs, namely, identification, inverse filtering and applications. READ MORE

  3. 3. 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. 4. Aerodynamic measurements of normal voice

    Author : Eva Holmberg; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Normal voice; inverse filtering; glottal airflow waveform; subglottal air pressure; Phonetics; Fonetik; Phonetics; fonetik;

    Abstract : Vocal fold vibration results from an alternating balance between subglottal air pressure that drives the vocal folds apart and muscular, elastic, and restoring forces that draw them together. The aim of the present thesis is to present quantitative data of normal vocal function using a noninvasive method. READ MORE

  5. 5. Why so different? - Aspects of voice characteristics in operatic and musical theatre singing : Aspects of voice characteristics in operatic and musical theatre singing

    Author : Eva Björkner; Anders Askenfelt; Ronald C. Scherer; KTH; []
    Keywords : HUMANIORA; HUMANITIES; operatic singing; musical theatre singing; voice source; subglottal pressure; flow glottogram; inverse filtering; formant frequencies; amplitude quotient AQ ; Music; Musikvetenskap;

    Abstract : This thesis addresses aspects of voice characteristics in operatic and musical theatre singing. The common aim of the studies was to identify respiratory, phonatory and resonatory characteristics accounting for salient voice timbre differences between singing styles. READ MORE
