Director: Tanya L. Eadie, Ph.D.    Auditory-perceptual Evaluation of Voice Auditory-perceptual evaluation is an important clinical tool used in voice diagnosis, assessment, and treatment. However, the rated quality a listener derives from a signal may be affected systematically by several factors related to: 1) the listener (e.g., individual bias, experience, training); 2) the task (e.g., scale used, dimensions rated); 3) the interaction between listener and task factors. This research investigates the effect of both listener and task factors on listeners' evaluation of individuals with voice disorders. For example, what is the effect of training on accuracy and reliability listener judgments? What types of voice qualities and dimensions are important when evaluating individuals with voice disorders? What types of scales are valid for evaluating voice disorders? How do auditory-perceptual ratings relate to other measures of voice such as acoustic characteristics, or those self-rated by the individual? Results have implications for accurate diagnosis and measurement of treatment outcomes for individuals with voice disorders.          Laryngectomy Rehabilitation Individuals diagnosed with laryngeal cancer undergo a variety of medical treatments and rehabilitation approaches. Although radiation therapy remains a primary management technique, total laryngectomy (total removal of the larynx) continues to be a treatment method. As a consequence of total laryngectomy, individuals must learn a new method of verbal communication, as well as learning to cope with anatomical and physiological changes and potential psychosocial consequences. While restoration of verbal communication is a critical factor in recovery, other factors also affect one's quality of life postlaryngectomy. These factors include physical functioning, airway and pain management, swallowing/eating, emotional well-being, coping mechanisms, social support, etc. This research investigates the relationship between these multidimensional factors (e.g., communication type and ability, social support, etc.) and other factors related to the individual (e.g., gender, age, education) that may impact quality of life postlaryngectomy.
