The aim of the study was to examine the effects of resonant voice therapy (RVT) on the vocal resonance of trained Carnatic singers. The specific objectives were to evaluate the effects of resonant voice therapy on the auditory perceptual judgments and acoustic source and tract parameters before and after RVT on phonation and sung voice samples.
Six vocally healthy trained Carnatic singers, three males and three females aged 18-25 years (M = 23; S.D = 2.09) participated in the study. All the participants were assigned to a 21-days-long Resonance Voice Therapy (RVT) training program. The participants' pre and post training phonation and sung samples were subjected to auditory perceptual analysis and acoustic analysis.
The results revealed that the post training auditory perceptual ratings of the phonation task showed a statistically significant difference from the pre training scores (Z= 2.35; P = 0.019). While for the singing task, the post training perceptual ratings were not significantly different from the pre training perceptual rating scores (Z= 2.66; P = 0.08). A significant difference was observed between the pre and post training values for all the measured acoustic parameters of the phonation task. In singing task, though the fundamental frequency, third and fourth formant frequencies showed no significant difference in the pre and post training conditions (P > 0.05), the parameter of- difference between the first formant frequency and the fundamental frequency showed a significant decrease (P = 0.028).
The effects of resonant voice production led to a high vocal economy, as evidenced from the improved source and filter acoustic parameters. Indication for formant tuning through vocal tract modifications, probably an enlarged pharyngeal area resulting in increased resonant voice quality in both phonation and singing tasks, is inferred from these results.
本研究旨在探讨共振嗓音疗法（RVT）对训练有素的卡纳蒂克音乐歌手嗓音共鸣的影响。具体目标是评估共振嗓音疗法对发声和歌唱嗓音样本在RVT前后的听觉感知判断以及声源和声道参数的影响。
六名嗓音健康、年龄在18 - 25岁之间（平均年龄M = 23岁；标准差S.D = 2.09）的训练有素的卡纳蒂克音乐歌手（三名男性和三名女性）参与了本研究。所有参与者都参加了为期21天的共振嗓音疗法（RVT）训练项目。对参与者训练前后的发声和歌唱样本进行听觉感知分析和声学分析。
结果显示，发声任务的训练后听觉感知评分与训练前得分存在统计学显著差异（Z = 2.35；P = 0.019）。而对于歌唱任务，训练后的感知评分与训练前的感知评分没有显著差异（Z = 2.66；P = 0.08）。发声任务的所有测量声学参数在训练前后的值之间存在显著差异。在歌唱任务中，尽管基频、第三和第四共振峰频率在训练前后条件下没有显著差异（P > 0.05），但第一共振峰频率与基频之间的差值参数显示出显著下降（P = 0.028）。
共振发声的效果导致了较高的嗓音经济性，这从声源和滤波器声学参数的改善中得到证明。从这些结果可以推断，通过声道调整进行共振峰调谐的迹象，可能是咽部区域扩大导致发声和歌唱任务中共振嗓音质量提高。
