  1. 1. Estimation of Speaker Age : Effects of Speech Properties and Speech Material

    Författare :Sara Skoog Waller; Mårten Eriksson; Billy Jansson; Mittuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Age estimation; Voice perception; Speech properties; Speech rate; Vocal disguise; Age disguise; Accuracy; Confidence; Spontaneous speech;

    Sammanfattning : The aim of this thesis was to investigate factors related to accuracy in estimation of speaker age and the role of certain speech properties in perception and manipulation of speaker age, as well as their interaction with the speech material that the age estimates were based on. This thesis consists of three studies. LÄS MER

  3. 2. Anchoring biases in estimations of age, weight and height

    Författare :Linda Langeborg; Mårten Eriksson; Peter Juslin; Mittuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; anchoring; anchor effects; own-anchor effect; assimilation; contrast; age estimation; weight estimation; height estimation; social judgments;

    Sammanfattning : The main purpose of this thesis was to study the circumstances under which anchoring biases occur for estimation of age, weight and height. Paper I investigated accuracy and biases in age estimates made by salespersons with experience in age estimation, compared to a control group without any similar experience. LÄS MER

  4. 3. Thermal crack estimation in early age concrete : models and methods for practical application

    Författare :Mårten Larson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Control of thermal cracking in young concrete is of great importance to ensure a desired service life time and function of a structure. Making reliable thermal stress estimations, and thereby conclusions about cracking risks, involves advanced modelling of material properties and structural restraint. LÄS MER

  5. 4. Adaptive model-based battery management - Predicting energy and power capability

    Författare :Björn Fridholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; state-of-charge estimation; state estimation; lithium-ion batteries; Battery management; parameter estimation;

    Sammanfattning : The battery is the limiting system for automotive electrication due to cost, size, and uncertain degradation. To be competitive the battery must therefore be used optimally. LÄS MER

  7. 5. Perception, Analysis and Synthesis of Speaker Age

    Författare :Susanne Schötz; Fonetik; []
    Nyckelord :HUMANIORA; HUMANITIES; phonology; perceptual cues; speaker age; automatic speaker recognition; acoustic analysis; acoustic correlates; data-driven; Phonetics; formant synthesis; Fonetik; fonologi; Technological sciences; Teknik;

    Sammanfattning : Speaker age is an important paralinguistic feature in speech which has to be considered in the study of phonetic variation. Knowledge about this feature may be used to improve speech technology applications, e.g. automatic speech recognition and speech synthesis. LÄS MER
