“…32-35 Overall, increased autonomic arousal has been found to detrimentally affect the speech motor system, leading to disfluency and decreased speech motor stability. 23, 31, 36 However, the effects of increased cognitive load and the related autonomic arousal on features of vocal motor control are less clear.…”

Objectives/Hypothesis The purpose of this study was to determine the relationship among cognitive load condition and measures of autonomic arousal and voice production in healthy adults. Study Design Prospective. Methods Sixteen healthy young adults (eight females) produced a sentence containing an embedded Stroop task in each of two cognitive load conditions: congruent and incongruent. In both conditions, participants said the font color of the color words instead of the word text. In the incongruent condition, font color differed from the word text, creating an increase in cognitive load relative to the congruent condition in which font color and word text matched. Three physiologic measures of autonomic arousal (pulse volume amplitude, pulse period, and skin conductance response amplitude) and four acoustic measures of voice (sound pressure level, fundamental frequency, cepstral peak prominence, and low-to-high spectral energy ratio) were analyzed for eight sentence productions in each cognitive load condition per participant. Results A logistic regression model was constructed to predict the cognitive load condition (congruent or incongruent) using subject as a categorical predictor and the three autonomic measures and four acoustic measures as continuous predictors. It revealed that three variables were significantly associated with cognitive load condition: skin conductance response amplitude, cepstral peak prominence, and the low-to-high spectral energy ratio. Conclusions During speech produced under increased cognitive load, healthy young adults show changes in physiologic markers of heightened autonomic arousal and acoustic measures of voice quality. Future work is necessary to examine these measures in older adults and individuals with voice disorders.
