A listener's judgement on the perceptual distance between two sounds usually draws on their psychoacoustic difference, but can also be subject to L1-specific perception. This study investigates the interplay between these two aspects when evaluating the perceptual distance of sound pairs. Mandarin and English listeners rated the perceptual distance of consonant-vowel pairs corresponding to sequences legal or illegal in their L1s. The results suggested that a similarity rating task can provide a finer assessment of distinctiveness between sound pairs as compared to a discrimination task. The results also showed how psychoacoustic perception may interact with L1-specific perception in this process.
听者对两个声音之间感知距离的判断通常基于它们的心理声学差异，但也可能受到母语特定感知的影响。本研究调查了当评估声音对的感知距离时，这两个方面之间的相互作用。汉语和英语听者对与其母语中合法或非法序列相对应的辅音-元音对的感知距离进行了评分。结果表明，与辨别任务相比，相似性评分任务可以更精细地评估声音对之间的区别度。结果还显示了在这个过程中，心理声学感知如何与母语特定感知相互作用。
