The harmonic sieve has been proposed as a mechanism for excluding extraneous frequency components from the estimate of the pitch of a complex sound. The experiments reported here examine whether a harmonic sieve could also determine whether a particular harmonic contributes to the phonetic quality of a vowel. Mistuning a harmonic in the first formant region of vowels from an /I/-/e/ continuum gave shifts in the phoneme boundary that could be explained by (i) phase effects for small amounts of mistuning and (ii) a harmonic sievelike grouping mechanism for larger amounts of mistuning. Similar grouping criteria to those suggested for pitch may operate for the determination of first formant frequency in voiced speech.
谐波筛已被提出作为一种从复合声音的音高估计中排除无关频率成分的机制。本文报道的实验研究了谐波筛是否还能确定特定谐波是否对元音的语音质量有贡献。对来自 /I/-/e/ 连续体的元音第一共振峰区域的谐波进行失谐，会导致音素边界发生偏移，这可以通过以下两种情况来解释：（i）少量失谐时的相位效应，以及（ii）大量失谐时类似谐波筛的分组机制。与音高确定所建议的类似分组标准可能在浊音语音的第一共振峰频率确定中起作用。
