•Acoustic reflex characteristics were studied in six persons with spastic dysphonia. Two methods of analysis were used: (1) a double-blind qualitative judgment of acoustic reflex recordings, and (2) a quantitative analysis of specific temporal characteristics of the acoustic reflexes. Judgments of reflex recordings did not reliably differentiate spastic dysphonia subjects from controls. An analysis of five latency measures revealed a difference between groups only in one measure, reflex contraction time.
