The contribution of the nasal murmur and the vocalic formant transitions to perception of the [m]-[n] distinction in utterance-initial position preceding [i,a,u] was investigated, extending the recent work of Kurowski and Blumstein [J. Acoust. Soc. Am. 76, 383-390 (1984)]. A variety of waveform-editing procedures were applied to syllables produced by six different talkers. Listeners' judgments of the edited stimuli confirmed that the nasal murmur makes a significant contribution to place of articulation perception. Murmur and transition information appeared to be integrated at a genuinely perceptual, not an abstract cognitive, level. This was particularly evident in [-i] context, where only the simultaneous presence of murmur and transition components permitted accurate place of articulation identification. The perceptual information seemed to be purely relational in this case. It also seemed to be context specific, since the spectral change from the murmur to the vowel onset did not follow an invariant pattern across front and back vowels.
研究了鼻辅音杂音和元音共振峰过渡对位于[i、a、u]之前的词首位置的[m]-[n]区别感知的贡献，扩展了库罗夫斯基和布卢姆斯坦最近的研究工作[《美国声学学会杂志》76, 383 - 390 (1984)]。对六位不同说话者发出的音节应用了各种波形编辑程序。听众对编辑后刺激的判断证实，鼻辅音杂音对发音部位感知有显著贡献。杂音和过渡信息似乎是在真正的感知层面而非抽象认知层面整合的。这在[-i]语境中尤为明显，在该语境中，只有杂音和过渡成分同时存在才能准确识别发音部位。在这种情况下，感知信息似乎纯粹是关系性的。它似乎也依赖于语境，因为从杂音到元音起始的频谱变化在前后元音之间并非遵循不变的模式。
