Abstract

Speech therapy exercises are not considered effective to reduce hypernasality in the speech of children with cleft palate. Previous research studies have shown that nasalance scores of hypernasal speakers were lower in backward and higher in forward voice focus. Conversely, some individual speakers had lower nasalance scores in forward voice focus. The present study sought to replicate and further expand these findings. The study investigated how many hypernasal speakers in a small convenience sample could lower their nasalance using voice focus. For 6 hypernasal speakers (4 F, 2 M, ages 5-18) with repaired cleft palate, nasalance scores were recorded for a non-nasal sentence, a nasal sentence, 2 phonetically varied sentences and a short song at baseline, in backward voice focus, in forward voice focus and at a final baseline. For individual speakers, reductions in nasalance of -10% from baseline were considered meaningful. Mean nasalance scores for all stimuli combined changed significantly from 58.2% nasalance (SD 11.3) at baseline to 44.2% (SD 15.3) in backward voice focus, 60.8% (SD 17.6) in forward voice focus, and 53.0% (SD 11.9) at the final baseline. Nasalance scores in the backward voice focus were significantly lower than the initial baseline and forward voice focus conditions. Inspection of individual scores showed that 4 of the 6 participants showed pronounced reductions in nasalance scores of up to -44% in backward and up to -23% in forward voice focus. Further research about the potential effectiveness of this approach for speech therapy should be undertaken.

调焦降低高鼻音说话者的鼻平衡评分:结果的重复和扩展。
语言治疗练习被认为不能有效地减少腭裂儿童的鼻音。先前的研究表明,高鼻音说话者的鼻平衡分数在向后聚焦时较低,而在向前聚焦时较高。相反,一些说话者在前向语音聚焦方面的鼻音平衡得分较低。本研究试图复制并进一步扩展这些发现。该研究调查了在一个小样本中,有多少高鼻音说话者可以通过语音聚焦来降低鼻音平衡。对6名重度鼻音说话者(4名F, 2名M,年龄5-18岁)腭裂修复后,在基线、后向语音聚焦、前向语音聚焦和最终基线时记录一个非鼻音句子、一个鼻音句子、2个语音变化句子和一首短歌的鼻音平衡评分。对于个别说话者来说,鼻音平衡从基线下降-10%被认为是有意义的。所有刺激组合的平均鼻平衡评分从基线时的58.2% (SD 11.3)显著变化为向后语音聚焦时的44.2% (SD 15.3)、向前语音聚焦时的60.8% (SD 17.6)和最终基线时的53.0% (SD 11.9)。后向语音聚焦条件下的Nasalance得分显著低于初始基线和前向语音聚焦条件。对个人得分的检查显示,6名参与者中有4名在向后和向前语音聚焦方面的鼻音平衡得分明显下降,分别高达-44%和-23%。关于这种方法在言语治疗中的潜在有效性的进一步研究应该进行。
