Profiles of fundamental frequency sound pressure levels and voice duration are measured separately in clinical practice. It was the aim of the present study to combine the two examinations, in order to estimate the relationship between pitch, sound pressure level and voice duration and to develop a new computer-assisted graph. A three-dimensional (3D) wireframe phonogram was constructed based on SPL profiles to obtain a general view of the parameters recorded. We have termed this "phonetography". Variable further projections were selected for the analysis of different aspects of parametric relationships. The results in 21 healthy volunteers and 4 patients with hyperfunctional dysphonias demonstrated that there were three typical figures of the 3D phonograms produced, depending on the relationship between voice duration when soft ("piano") compared to loud ("forte"). In one-third of the healthy volunteers, the values of the piano voice duration were greater than those of forte for almost all pitches examined. In two-thirds of the healthy subjects the values of forte voice duration were partly greater, as were those of piano voice duration. All of the patients showed voice duration values greater for forte than for piano. The results of the study demonstrate that the 3D phonogram is a useful tool for obtaining new insights into various relationships of voice parameters.
在临床实践中，基频声压级和嗓音持续时间的概况是分别测量的。本研究的目的是将这两项检查结合起来，以估计音高、声压级和嗓音持续时间之间的关系，并开发一种新的计算机辅助图表。基于声压级概况构建了三维（3D）线框语音图，以获得所记录参数的总体视图。我们将此称为“语音描记法”。选择了可变的进一步投影来分析参数关系的不同方面。21名健康志愿者和4名功能性发声亢进患者的结果表明，根据轻柔（“弱音”）与响亮（“强音”）时嗓音持续时间的关系，所产生的3D语音图有三种典型图形。在三分之一的健康志愿者中，几乎所有检查音高的弱音嗓音持续时间值都大于强音嗓音持续时间值。在三分之二的健康受试者中，强音嗓音持续时间值部分更大，弱音嗓音持续时间值也是如此。所有患者的强音嗓音持续时间值都大于弱音嗓音持续时间值。研究结果表明，3D语音图是一种有用的工具，可用于深入了解嗓音参数的各种关系。
