This study employed acoustic measures as well as auditory-perceptual assessments to examine the effects of voice therapy in children presenting with benign vocal fold lesions.
A retrospective, observational cohort design was employed. Sustained vowels produced by 129 children diagnosed with benign vocal fold lesions were analyzed, as well as connected speech samples produced by 47 children. Treatment outcome measures included Consensus of Auditory-Perceptual Evaluation of Voice (CAPE-V), jitter, shimmer, Noise-to-Harmonic Ratio (NHR), cepstral peak prominence (CPP), and Low-to-High Ratio (LHR) on sustained vowels, and CPP and LHR on connected speech.
Following voice therapy, significant improvements in CAPE-V ratings (p < 0.001) were observed. Additionally, jitter (p = 0.041), NHR (p = 0.019), and CPP (p < 0.01) on sustained vowels, and CPP (p = 0.002), and LHR (p = 0.008) on connected speech significantly improved following voice therapy. CPP increased with age in males but did not change in females. CAPE-V ratings and perturbation measures indicated that dysphonia was more severe in younger children pre and post-therapy.
Auditory-perceptual and acoustic measures demonstrated improved voice quality following voice therapy in children with dysphonia. CPP effectively quantified voice therapy gains and allowed for analysis of connected speech, in addition to sustained vowels. These findings demonstrate the value of CPP as a tool in assessing therapy outcomes and support the efficacy of voice therapy for children presenting with vocal fold lesions.

本研究采用声学测量和听觉感知评估来检查嗓音治疗对患有良性声带病变的儿童的影响。
采用回顾性观察队列设计。对 129 名被诊断患有良性声带病变的儿童的持续元音和 47 名儿童的连续言语样本进行了分析。治疗效果评估指标包括：共识性听觉感知嗓音评估（CAPE-V）、抖动、声扰比（NHR）、倒频谱峰值突出度（CPP）和低至高比（LHR）在持续元音上，以及 CPP 和 LHR 在连续言语上。
嗓音治疗后，CAPE-V 评分显著改善（p<0.001）。此外，在持续元音上的抖动（p=0.041）、NHR（p=0.019）和 CPP（p<0.01），以及在连续言语上的 CPP（p=0.002）和 LHR（p=0.008）也显著改善。CPP 在男性中随年龄增长而增加，但在女性中无变化。CAPE-V 评分和扰动测量表明，治疗前和治疗后，年龄较小的儿童的发音障碍更严重。
听觉感知和声学测量显示，患有发音障碍的儿童在接受嗓音治疗后，嗓音质量得到改善。CPP 有效地量化了嗓音治疗的效果，并允许对连续言语进行分析，除了持续元音。这些发现表明 CPP 作为一种工具在评估治疗效果方面具有价值，并支持嗓音治疗对患有声带病变的儿童的疗效。
