By means of measuring fundamental frequency, amplitude and voice quality (signal-to-noise ratio) of voiced signal segments in speech, a three-dimensional representation was established. The record of voice quality versus pitch and intensity overcomes all the disadvantages which are met within the voice field (sustained vowels, extreme voice sound pressures, missing quality information etc.).
通过测量语音中浊音信号段的基频、幅度和语音质量（信噪比），建立了三维表示。语音质量与音高和强度的记录克服了语音领域中遇到的所有缺点（持续元音、极端语音声压、质量信息缺失等）。
