目的通过客观声学分析来评估语音手术后声音的改善情况。材料和方法这项前瞻性研究于 2002 年 12 月至 2008 年在新德里 Maulana Azad 医学院进行。这项研究包括 100 名受试者，包括所有年龄组和性别。所有这些器质性嗓音障碍患者在语音手术前后均使用 VAUGMI 语音分析程序进行言语分析。结果治疗前所有语音分析参数均出现紊乱，但手术后所有参数均应有所改善。最显着的变化是抖动。结论在进行这项研究后，我们发现使用声学分析的各种参数（如基频、谐波噪声比、抖动、闪烁、S/z 比）对嘶哑声音进行分析有助于我们识别声音嘶哑的程度以及与声音相关的严重程度。它。抖动和闪烁等一些参数能够检测到感知正常声音中的嘶哑成分，因此患者可以通过在适当的时间进行手术和声音治疗来帮助患者。
ObjectiveTo evaluate voice improvement after phonosurgery by objective acoustic analysis.Material and methodsThis prospective study was conducted in Maulana Azad Medical college New Delhi from December 2002 to 2008. In this study 100 subjects were included comprising of all age groups and either sex. All these patients with organic voice disorder underwent speech analysis using VAUGMI speech analysis program before and after phonosurgery.ResultAll the parameter of voice analysis were deranged before the treatment but after surgery all the parameters should improvement most significant change was seen in the jitter.ConclusionAfter doing this study we found that the analysis of hoarse voice using various parameters of acoustic analysis like fundamental frequency, harmonics to noise ratio, jitter, shimmer, S/z ratio helped us in identifying the degree of hoarseness and the severity related to it. Some parameters like jitter and shimmer were able to detect the component of hoarseness in perceptually normal voice and thus patient was helped by doing surgery and voice therapy at the appropriate time.
