The purpose of the current study was to determine how maximum phonation duration (MPD) of five notes (C4, D4, E4, F4, G4) sustained on /o/, sustained vowels (/i/, /ae/, /a/, /u/), and s/z ratio (sustained /s/ and /z/) changed during voice therapy for vocal nodules. Voices of adult females before treatment and after resolution of vocal nodules were analyzed via the PM Pitch Analyzer. Treatment included tension reduction, abuse identification and elimination, laryngeal strengthening, and home exercises. Results indicate there was no significant difference in maximum phonation duration or S/Z ratio before and after treatment. Results revealed that females with vocal nodules demonstrate measurements before therapy similar to measures considered to be normal in persons without vocal nodules. Application of findings to clinical practice is discussed.
本研究的目的是确定在针对声带小结的嗓音治疗过程中，发/o/音时五个音符（C4、D4、E4、F4、G4）的最大发声时长（MPD）、持续元音（/i/、/æ/、/a/、/u/）以及s/z比率（持续发/s/和/z/音）是如何变化的。通过PM音高分析仪对成年女性在治疗前和声带小结消退后的嗓音进行分析。治疗包括减轻紧张、识别并消除滥用嗓音的行为、增强喉部力量以及家庭练习。结果表明，治疗前后最大发声时长或S/Z比率没有显著差异。结果显示，有声带小结的女性在治疗前的测量结果与无结节者被认为正常的测量结果相似。本文还讨论了研究结果在临床实践中的应用。
