OBJECTIVES
To explore the immediate effects of voice focus adjustments on the oral-nasal balance of hypernasal speakers, measured with nasalance scores.
METHODS
Five hypernasal speakers (2 M, 3 F) aged 5-12 (SD 2.7) learned to speak with extreme forward and backward voice focus. Speakers repeated oral, nasal, and phonetically balanced stimuli. Nasalance scores were collected with the Nasometer 6450.
RESULTS
From the average baseline of 34.27% for the oral stimulus, nasalance increased to 46.07% in forward and decreased to 30.2% in backward focus. From the average baseline of 64.53% for the nasal stimulus, nasalance decreased to 64.13% in forward and decreased to 51.73% in backward focus. From the average baseline of 51.33% for the phonetically balanced stimulus, nasalance increased to 58.87% in forward and decreased to 46.2% in backward focus.
CONCLUSIONS
Forward voice focus resulted in higher and backward voice focus resulted in lower nasalance scores during speech for a group of hypernasal speakers. However, there was an exception: One male speaker showed decreased nasalance in forward voice focus. Future research should investigate the longer-term effectiveness of the intervention.
目的
探讨语音聚焦调整对鼻音过重者口鼻平衡的即时影响，通过鼻音计得分进行测量。
方法
5名年龄在5至12岁（标准差2.7）的鼻音过重者（2名男性，3名女性）学习用极端靠前和靠后的语音聚焦方式说话。参与者重复口腔、鼻腔和语音平衡的刺激材料。使用Nasalometer 6450收集鼻音计得分。
结果
对于口腔刺激材料，从平均基线的34.27%开始，在靠前聚焦时鼻音计得分增加到46.07%，在靠后聚焦时降至30.2%。对于鼻腔刺激材料，从平均基线的64.53%开始，在靠前聚焦时鼻音计得分降至64.13%，在靠后聚焦时降至51.73%。对于语音平衡刺激材料，从平均基线的51.33%开始，在靠前聚焦时鼻音计得分增加到58.87%，在靠后聚焦时降至46.2%。
结论
对于一组鼻音过重者，在说话时靠前的语音聚焦导致鼻音计得分较高，靠后的语音聚焦导致得分较低。然而，有一个例外：一名男性参与者在靠前语音聚焦时鼻音计得分降低。未来的研究应调查该干预措施的长期效果。
