Normative nasalance scores are essential for the treatment and assessment purposes for clinicians. Till date, no studies have been done on nasalance in Estonia. This research was conducted to develop Estonia-specific optimized speech stimuli for Nasometer II and establish the normative nasalance scores. Ninety-two randomly selected healthy and 14 cleft palate Estonian monolingual children, aged four to seven years, were included as participants. Estonian language-specific test material was developed. The Estonian test material consisted of 24 speech stimuli. Based on the phoneme content, the stimuli were divided into three groups: (1) sentences that included oral and nasal phonemes and targeted the same phoneme distribution as in spontaneous speech, (2) sentences that included only oral phonemes and (3) sentences that were loaded with nasal phonemes. Nasometer II software was used to calculate the nasalance scores for each child and each sentence. Results indicated that there were significant differences in nasalance scores for oronasal and oral stimuli scores, and no significant differences were found in nasal stimuli scores between the study and control group. The threshold for oronasal stimuli was 42.1-18.9, oral stimuli was 27.9-3.9 and nasal stimuli was 69.4-46.2. In conclusion, Estonia-specific optimized speech stimuli were developed and normative nasalance scores were established. These normative scores can be used for the diagnosis and follow-up treatment of patients with resonance disorders, especially for patients with cleft palate.
规范的鼻音评分对于临床医生的治疗和评估目的至关重要。迄今为止，爱沙尼亚尚未开展关于鼻音的研究。本研究旨在为爱普诺II型鼻声计开发爱沙尼亚语专用的优化语音刺激，并确定规范的鼻音评分。92名随机挑选的4至7岁健康爱沙尼亚语单语儿童和14名单腭裂儿童作为参与者。开发了爱沙尼亚语专用测试材料。爱沙尼亚语测试材料由24个语音刺激组成。根据音素内容，刺激被分为三组：（1）包含口腔音和鼻音且目标音素分布与自发语音相同的句子，（2）仅包含口腔音的句子，（3）充满鼻音的句子。使用爱普诺II型鼻声计软件计算每个儿童和每个句子的鼻音评分。结果表明，口鼻音和口腔音刺激评分的鼻音评分存在显著差异，研究组和对照组在鼻音刺激评分上未发现显著差异。口鼻音刺激的阈值为42.1 - 18.9，口腔音刺激为27.9 - 3.9，鼻音刺激为69.4 - 46.2。总之，开发了爱沙尼亚语专用的优化语音刺激并确定了规范的鼻音评分。这些规范评分可用于共振障碍患者的诊断和后续治疗，尤其是腭裂患者。
