Surface electromyographic (EMG) signals were detected from the laryngeal area of 7 normal and 7 vocally hyperfunctional speakers during rest, two resisted-force maneuvers, vowel production, and connected speech. Vowel fundamental frequency, absolute and relative period perturbation, laryngeal-palpation ratings, and harshness ratings were acquired as well. The two groups differed significantly on all EMG measures except those associated with the resisted-force maneuvers, the vowel EMG-to-rest EMG ratio, and the speech EMG-to-rest EMG ratio. Moderately high correlations were evident between selected clinical measures and speech EMG values.
在休息、两种抗阻动作、元音发声和连贯言语期间，从7名正常发声者和7名发声功能亢进者的喉部区域检测表面肌电图（EMG）信号。同时获取元音基频、绝对和相对周期扰动、喉部触诊评分和粗糙度评分。除了与抗阻动作、元音EMG与静息EMG比值以及言语EMG与静息EMG比值相关的指标外，两组在所有EMG测量指标上均存在显著差异。所选临床指标与言语EMG值之间存在中度高度相关性。
