Abstract
Pairs of "one-formant pulses" with 10 ms onset-to-onset interval and highly different F values for the first and the second pulse (LH and HL pairs) were used in vowel identification experiment. Response distributions corresponding to these stimuli and to "stationary" two-formant and one-formant pulse pairs were compared to calculate the phonetic distance between stimuli. The results are in favour of low-pass filtering of excitation pattern with sampling at the stimulus offset.
摘要
在元音识别实验中，使用了起始间隔为10毫秒的“单共振峰脉冲”对，且第一个和第二个脉冲的F值差异很大（LH和HL对）。将与这些刺激以及“固定”双共振峰和单共振峰脉冲对相对应的反应分布进行比较，以计算刺激之间的语音距离。结果支持在刺激偏移时进行采样的激励模式低通滤波。
