Effects of Cognitive Load on Vocal Fold Vibratory Patterns in Bilingual Speakers of Low and High German.

Objectives: Increased cognitive load has been observed to correlate with decreased vocal fold perturbation, reduced additive noise, increased periodicity, and a higher rate of vocal fold vibration. The aim of this study was to explore whether vocal fold vibratory patterns can serve as indicators of increased cognitive load in nonbalanced bilingual speakers when they use their weaker language.

Study Design: This is a comparative experimental study with a within-speaker design.
