The main aim of this study was to analyse the change in voice in terms of acoustic parameters and its perceptual impact in patients who have undergone tonsillectomy. A prospective study was conducted in our institution-JSS Hospital and JSS institute of speech and hearing, Mysore for a duration of 1 year (December 2015-December 2016). 50 post tonsillectomy cases were selected randomly and subjected to acoustic analysis. It was inferred that situation of vocal analysis and assessment for the vowels 'a', 'i' and 'u' under the categories hoarse, harsh and breathy remain more or less the same during preoperative stages, first preoperative follow up and the second post operative follow up. It was concluded that tonsillectomy did not appear to change the acoustic features of vowels remarkably. It was assumed that the subject may adjust the shape of the vocal tract to produce consistent speech sound after surgery using auditory feedback.
本研究的主要目的是分析扁桃体切除术后患者声音在声学参数方面的变化及其感知影响。在我们的机构——迈索尔的JSS医院和JSS言语与听力研究所进行了一项为期1年（2015年12月至2016年12月）的前瞻性研究。随机选择50例扁桃体切除术后病例并进行声学分析。据推断，在术前阶段、首次术前随访和第二次术后随访期间，在嘶哑、粗糙和呼吸声类别下对元音“a”、“i”和“u”进行的语音分析和评估情况大致相同。得出的结论是，扁桃体切除术似乎并未显著改变元音的声学特征。据推测，受试者可能会在术后利用听觉反馈调整声道形状以产生一致的语音。
