比较了光谱技术和线性预测分析在共振峰频率测量中的准确性。前三个共振峰频率是由三个有经验的频谱阅读器和线性预测分析测量的90个合成语音标记。对于100和300赫兹之间的基频，两种方法的精度都在近似值内，对于第一和第二共振峰都是±60赫兹。用线性预测法测量第三共振峰的准确度相同，但用光谱学方法只能测量到±110以内。当基频大于或等于350赫兹时，这两种方法的精度都会大大降低。这些测量极限似乎在共振峰频率的差异界限范围内。
The accuracy of spectrographic techniques and of linear prediction analysis in measuring formant frequencies is compared. The first three formant frequencies 90 synthetic speech tokens were measured by three experienced spectrographic readers and by linear prediction analysis. For fundamental frequencies between 100 and 300 Hz, both methods are accurate to within approximatey , ±60 Hz for both first and second formants. The third formant can be measured with the same degree of accuracy by linear prediction, but only to within ± 110 by spectrographic means. The accuracy of both methods decreases greatly when fundamental frequency is 350 Hz or greater. These limits of measurement appear to be within the range of the difference limens for formant frequencies
