SPEECH PERCEPTION WITH PROMONTORY STIMULATIONa

Clinical Analysis of Laryngeal Trauma Secondary to Intubation

“…It is caused by a temporal irregularity of glottic closure. Vocal quality may, in these cases, improve with time as auditorily-directed postural compensations are made by the larynx and learned centrally (Fourcin et al 1983). The "physical dimensions of the paediatric larynx are continually changing as a result of growth.…”

Speech deterioration in postlingually deafened adults

“…Fourcin et al (1983) report that their deaf subject's control of the range and regularity of her fundamental frequency improved markedly when they supplied her feedback about her voice pitch over a promontory electrode and adjunctire therapy. On the other hand, Waldstein (1989) had seven speakers deafened postlingually at ages ranging from 6 to 40 and hearing age-matched controls read lists of eight nouns in isolation and found less period-to-period variability in voice pitch among the deaf speakers.…”

Cochlear Implant Characteristics: A Review of Current Technology

“…The London-based group of Douek, Fourchin, Moore, and colleagues (Douek et 25 SEMINARS IN HEARING-VOLUME 6, NUMBER 1, February 1985Fourcin et al, 1983) have adopted a unique approach to cochlear prostheses. They have designed a patient-removable extracochlear device, which provides speech pattern information specifically intended to maximize lipreading capabilities, rather than attempting to provide information regarding the entire speech code.…”
