| 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. |
