听觉场景分析在语音感知中的作用存在争议，特别是听者是否形成共振峰的感知流。在三个实验中，研究了元音共振峰频率在感知合成元音-鼻音节中的作用以及元音和鼻音节之间共振峰连续性的重要性。鼻音原型/m/和/n/在所有实验中使用，连同一系列的前元音不同的只是在频率和过渡的第二共振峰（F2）。当元音和鼻音之间没有明显的过渡时，随着元音F2的增加，每个鼻音的感知从/m/变化到/n/。引入明确的共振峰转换消除了这种影响，听众听到了每个鼻音原型的适当感知。然而，如果过渡和鼻原型是不一致的，则鼻原型仅由过渡决定。因此，在每一个实验中，元音F2过渡到鼻辅音的目标频率决定了鼻音，优先于鼻音原型的共振峰结构。结果没有显示出共振峰流的强有力的证据，更符合模式匹配过程。(C)2002 Elsevier Science B.

There is controversy over the role of auditory scene analysis in speech perception and in particular whether listeners form perceptual streams of formants. The role of vowel formant frequencies in the perception of synthetic vowel-nasal syllables and the importance of formant continuity between vowel and nasal were examined in three experiments. The nasal prototypes /m/ and /n/ were used in all experiments, together with a range of preceding vowels differing only in the frequency and transitions of their second formant (F2). When no explicit transitions were present between the vowel and nasal, the perception of each nasal changed from /m/ to /n/ as the vowel F2 increased. Introducing explicit formant transitions removed this effect, and listeners heard the appropriate percepts for each nasal prototype. However, if the transition and the nasal prototype were inconsistent, the percept was determined by the transition alone. In each experiment, therefore, the target frequency of the vowel F2 transition into the nasal consonant determined the percept, taking precedence over the formant structure of the nasal prototype. The results do not show strong evidence for formant streaming and are more consistent with pattern matching processes. (C) 2002 Elsevier Science B.V. All rights reserved.
