Lehoux, Hugo,
Biomechanics and acoustics of voice production [rukopis] / Hugo Lehoux. -- 2023. -- 98. -- Ved. práce Jan Švec. -- Abstract: Production of human voice involves complex biomechanical processes leading towards the vibration of the vocal folds, and acoustic processes resulting in production of the final sound of human voice. This PhD project will aim at uncovering the basic mechanisms involved in the vibration of the vocal folds and in the final voice production. Experiments on excised larynges will be used to determine the resonance properties of the vocal folds and to relate them to the fundamental frequency of the self-sustained vocal fold vibrations. The vocal fold vibrations will be captured by a high-speed camera and will be analyzed to obtain the details of the vibration characteristics. The characteristics will be compared to the behavior of physical and mathematical models of the vocal folds connected to the vocal tract. The changes of vibration characteristics due to changes of material properties of the vocal folds caused by physiologic and pathologic processes will be investigated in order to help clinicians in diagnosing voice problems more specifically.. -- Abstract: Production of human voice involves complex biomechanical processes leading towards the vibration of the vocal folds, and acoustic processes resulting in production of the final sound of human voice.
