语速的变化会影响对辅音中暂时定义的语音区别的感知，例如顿音，停顿-滑音和停顿-打音对比。这些对比的生产数据显示，在时间上不同的对上，不对称的影响，较长的成员表现出更明显的影响。这些数据进一步表明，这两个音节中较短的那个充当了语音锚点。这项研究调查了元音是否也有类似的影响。为此，我们研究了朝鲜语中短-长元音对的产生，这种语言具有音位元音长度。结果表明，长元音和短元音在不同的语速中都是不同的，因此辅音的对称效应在元音中没有发现。短元音不能提供语音上的支点：事实上，慢速发音的短元音的持续时间几乎总是与快速发音的长元音重叠。[NIH支持的工作。]
Variations in speaking rate affect the perception of temporally defined phonetic distinctions in consonants, such as voicing in stops, and the stop‐glide and stop‐affricate contrasts. The production data on these contrasts show asymmetrical effects on temporally distinctive pairs, with the longer members showing the effects more markedly. These data further suggest that the shorter member of the pair serves as a phonetic anchor. This study investigates whether similar effects emerge for vowels. To this end, production of short‐long vowel pairs was examined across speaking rates in Korean, a language that has phonemic vowel length. Results show that both long and short vowels vary across speaking rates, such that the symmetrical effects found for consonants are not found for vowels. Short vowels do not provide a phonetic anchor: In fact, the durations of short vowels produced at a slow rate nearly always overlap those of long vowels produced at a fast rate.
