Three parallel studies conducted with an early adolescent male subject deafened by meningitis at age 11 are reported. Study 1 plotted phonetic errors in spontaneous and read speech, long-term average spectra and vowel formant frequencies. Study 2 measured the subject's speech intelligibility using monosyllabic word lists. Study 3 involved normal hearer 's ratings of the subject's speech 2 months and 30 months after the onset of deafness. The results obtained revealed a deterioration in both speech intelligibility and quality.
报告了三项针对一名11岁因脑膜炎致聋的青春期早期男性受试者开展的平行研究。研究1绘制了自发言语和朗读言语中的语音错误、长期平均谱和元音共振峰频率。研究2使用单音节词表测量了该受试者的言语可懂度。研究3涉及正常听力者在耳聋发作后2个月和30个月对该受试者言语的评分。所获结果显示言语可懂度和质量均有所下降。
