Selected Aerodynamic Characteristics of Deaf Individuals during Various Speech and Nonspeech Tasks

Evidence for Auditory-Motor Impairment in Individuals With Hyperfunctional Voice Disorders

“…Like individuals with hyperfunctional voice disorders, speakers with hearing loss use higher laryngeal resistance (Higgins, Carney, & Schulte, 1994), and their voices are frequently described as strained and breathy (Arends, Povel, Van Os, & Speth, 1990;Forner & Hixon, 1977;Higgins et al, 1994;Read, 1989). These symptoms are speculated to be caused by laryngeal dysregulation and/or incoordination (Forner & Hixon, 1977;Itoh, Horii, Daniloff, & Binnie, 1982;Lane, Perkell, Svirsky, & Webster, 1991;Metz, Whitehead, & Whitehead, 1984). Furthermore, like individuals with hyperfunctional voice disorders, speakers with hearing loss also display deviations in speech breathing (Forner & Hixon, 1977;Perkell et al, 2000).…”

Breathing pattern and kinematics in normal subjects during speech, singing and loud whispering

“…Compared with quiet breathing (QB), speech and singing are characterized by shorter inspirations, longer expirations, larger lung volume excursions, higher and more sustained expiratory pressures with generally lower respiratory frequency (Bunn & Mead 1971, Hixon et al. 1973, 1976, Proctor 1980, Itoh et al. 1982, Hoit & Hixon 1987, Hodge & Rochet 1989, Hoit et al.…”

“…While previous studies have mainly focused on speech breathing (Bunn & Mead 1971, Hixon et al. 1973, 1976, Itoh et al. 1982, Proctor 1986, Hoit & Hixon 1987, Hodge & Rochet 1989, Hoit et al.…”

Longitudinal Changes in Children’s Speech and Voice Physiology after Cochlear Implantation

“…Although there have been some investigations of the speech physiology of adults with hearing loss (HL) (see for example, Higgins, Carney, & Schulte, 1994;Itoh, Horii, Daniloff, & Binnie, 1982;Lane, Perkell, Svirsky, & Webster, 1991;McGarr & Whitehead, 1992;Perkell, Lane, Svirsky, & Webster, 1992;Samar, Metz, Schiavetti, Sitler, & Whitehead, 1989;Svirsky, Lane, Perkell, & Wozniak, 1992), this type of assessment rarely has been applied to deaf children. One reason for this may be that young deaf children often have very limited, disordered, and variable speech production skills, making it difficult to apply standard speech physiological assessment procedures.…”
