The aim of the study was to assess the acoustic and capacity analyses of voice in academic teachers with hyperfunctional dysphonia using DiagnoScope Specialist software.
The study covered 46 female academic teachers aged 34-48 years. The women were diagnosed with hyperfunctional dysphonia (with absence of organic pathologies). Having obtained the informed consent, a primary medical history was taken, videolaryngoscopic and stroboscopic examinations were performed and diagnostic voice acoustic and capacity analyses were carried out using DiagnoScope Specialist software.
The acoustic analysis carried out of academic teachers with diagnosed hyperfunctional dysphonia showed enhancement in the following parameters: fundamental frequency (FO) by 1.2%; relative average perturbation (Jitter by 100.0% and RAP by 81.8%); relative amplitude perturbation quotient (APQ) by 2.9%; non-harmonic to harmonic ratio (U2H) by 16.0%; and noise to harmonic ratio (NHR) by 13.4%. A decrease of 2.5% from normal values was noted in relative amplitude perturbation (Shimmer). Formant frequencies also showed reduction (F1 by 10.7%, F2 by 5.1%, F3 by 2.2%, and F4 by 3.5%). The harmonic perturbation quotient (HPQ) was 0.8% lower and the residual harmonic perturbation quotient (RHPQ) 16.8% lower, with the residual to harmonic (R2H) decreasing by 35.1 per cent; the sub-harmonic to harmonic (S2H) by 2.4%; and the Yanagihara coefficient by 20.2%.
The capacity analysis with the DiagnoScope Specialist software showed figures significantly lower than normal values of the following parameters: phonation time, true phonation time, phonation break coefficients, vocal capacity coefficient and mean vocal capacity.
本研究旨在使用DiagnoScope Specialist软件对患有功能性发声障碍的高校教师进行嗓音声学和能力分析。
本研究涵盖了46名年龄在34至48岁之间的女性高校教师。这些女性被诊断为功能性发声障碍（无器质性病变）。在获得知情同意后，记录了基本病史，进行了视频喉镜和频闪喉镜检查，并使用DiagnoScope Specialist软件进行了嗓音声学和能力分析。
对被诊断为功能性发声障碍的高校教师进行的声学分析显示，以下参数有所增强：基频（FO）提高了1.2%；相对平均扰动（抖动率提高了100.0%，相对平均扰动率提高了81.8%）；相对幅度扰动商（APQ）提高了2.9%；非谐波与谐波比率（U2H）提高了16.0%；噪声与谐波比率（NHR）提高了13.4%。相对幅度扰动（闪烁）较正常值降低了2.5%。共振峰频率也有所降低（F1降低了10.7%，F2降低了5.1%，F3降低了2.2%，F4降低了3.5%）。谐波扰动商（HPQ）降低了0.8%，残余谐波扰动商（RHPQ）降低了16.8%，残余与谐波（R2H）降低了35.1%；次谐波与谐波（S2H）降低了2.4%；柳原系数降低了20.2%。
使用DiagnoScope Specialist软件进行的能力分析显示，以下参数的数值明显低于正常值：发声时间、实际发声时间、发声中断系数、发声能力系数和平均发声能力。
