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.
