Physiological differences between normal speakers and those with unilateral vocal cord paralysis are presented. Pressure readings taken intraorally and subglotically are compared during phonation of consonants requiring laryngeal closure and those not requiring cord approximation. From our studies, it is apparent that: (1) a significant difference in air pressure patterns exists between normal speakers and those with vocal cord paralysis, (2) the respiratory apparatus tends to alter normally constant airflow in cases of vocal fold paralysis and (3) either voice therapy or teflon cord injection will significantly alter the aerodynamic relationships from the untreated paralyzed state.
