  1. 1. Perception, Analysis and Synthesis of Speaker Age

    Detta är en avhandling från Linguistics and Phonetics

    Författare :Susanne Schötz; [2006]
    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

  2. 2. Drum sound from floor coverings - objective and subjective assessment

    Detta är en avhandling från Engineering Acoustics, LTH, Lund University

    Författare :Ann-Charlotte Johansson; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vakuumteknik; vibrationer; akustik; hydraulik; Maskinteknik; vacuum technology; vibration and acoustic engineering; hydraulics; acoustic standard; Mechanical engineering; tapping machine; veneer flooring; parquet flooring; binaural recording; foot impact; loudness; sound quality; listening test; paired comparisons; walking sound; drum sound; building acoustics; psychoacoustics; laminate flooring;

    Sammanfattning : Drum sound is the sound produced when an object, such as a foot, hits the flooring in the room in which the receiving ear is located. Drum sound has attracted interest in recent years, particularly due to an increased use of thin floating floor constructions, such as veneer or laminate flooring, which can produce loud and sharp walking sound.

  3. 3. Perceptual reorganization of vowels Separating the linguistic and acoustic parts of the mismatch response

    Detta är en avhandling från Stockholm : Department of Linguistics, Stockholm University

    Författare :Ellen Marklund; Francisco Lacerda; Iris-Corinna Schwarz; Riitta Salmelin; [2017]
    Nyckelord :HUMANIORA; HUMANITIES; language acquisition; infants; speech perception; MMR; MMN; perceptual reorganization; Linguistics; lingvistik;

    Sammanfattning : During the first year of life, infants go from perceiving speech sounds primarily based on their acoustic characteristics, to perceiving speech sounds as belonging to speech sound categories relevant in their native language(s). The transition is apparent in that very young infants typically discriminate both native and non-native speech sound contrasts, whereas older infants show better discrimination for native contrasts and worse or no discrimi­na­tion for non-native contrasts.

  4. 4. The role of glucocorticoid receptors and mitogen-regulated protein kinases in the cochlea

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Författare :Inna Meltser; Karolinska Institutet.; Karolinska Institutet.; [2009]

    Sammanfattning : Hearing loss induced by acoustic trauma is a common handicap for the human population. Acoustic trauma triggers a cascade of changes in the cochlea such as a direct mechanical damage of sensory hair cells, biochemical disturbances including reactive oxygen and nitrogen species generation, release of pro-inflammatory cytokines and exitotoxicity.

  5. 5. Communication quality a conceptual approach focusing on classroom assistive listening devices

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Johan Odelius; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : In a classroom an assistive listening device (ALD) is a system of external microphones that transmit sound from a sound source directly to students' hearing aids. An ALD can be a microphone close to the mouth which transmits a voice directly to listeners' hearing aids. LÄS MER
