Measuring communication effort in speech variability
Abstract
Interactive conversation is one of the most important activities
that is affected by hearing impairment.
• Measures of effort are important, in terms of both listening and
communication, in understanding hearing disability.
• The difficulty of communicating in a given situation may be
reflected in talkers’ speech production.
• Voicing jitter refers to short-term cycle-to-cycle variability in
fundamental frequency (Lieberman, 1961).
• Voicing jitter is affected by many factors, including vocal fold
stiffness, sub-glottal pressure and rate of airflow (Titze, 2000).
