UNASSIGNED: In a retrospective study, 29 women with a mean age of 25 years (± 8.9, range: 18-53) diagnosed with structural vocal fold pathologies were examined before and after voice therapy or phonosurgery. Both acoustic and EGG signals were recorded simultaneously during the phonation of the sustained vowels /ɑ/, /i/, and /u/ at three elicited levels of loudness (soft/comfortable/loud) and unconstrained F0 conditions.
UNASSIGNED: A linear mixed-model analysis showed a significant effect of elicitation effort levels on peak dEGG, HNR, and CPPS (all p < .01). Calibrated SPL significantly influenced HNR and CPPS (both p < .01). Furthermore, F0 had a significant effect on peak dEGG and CPPS (p < .0001). All metrics showed significant changes with regard to vowel (all p < .05). However, the treatment had no effect on the examined metrics, regardless of the treatment type (surgery vs. voice therapy).
UNASSIGNED: The value of the investigated metrics for voice assessment purposes when sampled without sufficient control of SPL and F0 is limited, in that they are significantly influenced by the phonatory context, be it speech or elicited sustained vowels. Future studies should explore the diagnostic value of new data collation approaches such as voice mapping, which take SPL and F0 effects into account.
■在一项回顾性研究中,在语音治疗或语音手术之前和之后,对29名平均年龄为25岁(±8.9,范围:18-53)的女性进行了检查。在持续元音的发声过程中,同时记录了声学和EGG信号/α/,/i/,和/u/在三个引起的响度水平(柔和/舒适/响亮)和不受约束的F0条件下。
■线性混合模型分析显示,激发努力水平对峰值dEGG有显著影响,HNR,和CPPS(所有p<0.01)。校准的SPL显著影响HNR和CPPS(均p<0.01)。此外,F0对峰dEGG和CPPS有显著影响(p<0.0001)。所有指标均显示出元音方面的显着变化(所有p<0.05)。然而,治疗对检查的指标没有影响,无论治疗类型如何(手术与语音治疗)。
■在没有充分控制SPL和F0的情况下进行采样时,用于语音评估目的的调查指标的值有限,因为它们受到语音语境的显著影响,无论是言语还是引起持续的元音。未来的研究应该探索新的数据整理方法的诊断价值,如语音映射,其中考虑了SPL和F0效应。
