PERCEPTION OF SPEECH SOUNDS

双重感知是一种实验室现象，其中一个刺激或 刺激成分同时促成两种不同知觉 在人类听众中。 这种现象的主要表现是 涉及改变语音的关键成分的质量 音节（/da/或/ga/），以便该成分作为单独的， 非言语事件（啁啾），同时也有助于感知 音节 重要的问题是这次示威 反映用于处理语音信息的专用模式，或者 听觉系统归因的广义知觉倾向 对特定声源的刺激。 多言语知觉 这种现象可以在非人类灵长类动物中复制。 感性 猴子所表现出的能力并不能完全归因于 人类的语音处理机制，可能是由于更一般的 听觉机制 相反，人类在感知任务上 倾听者成功，猴子失败是很好的潜在候选者， 人类的特殊处理机制。 双重知觉测验 对理论建设是有价值的，因为它们提供了一个关键的 两个对立的模型的初始状态的测试 人类语音处理的潜在机制。 1998年，我们 进行双重知觉测试与猕猴，使用合成/da/ 和/ga/音节作为刺激。 资助NIH赠款RR 00166和D C00520。

Duplex perception is a laboratory phenomenon where one stimulus or stimulus component simultaneously contributes to two distinct percepts in human listeners. The primary demonstrations of this phenomenon involve altering the quality of a critical component of a speech syllable (/da/ or /ga/) so that the component is heard as a separate, nonspeech event (a chirp) while also contributing to the perception of the syllable. The important question is whether this demonstration reflects a specialized mode for processing speech information, or a generalized perceptual tendency in the auditory system for attributing stimuli to a particular sound source. Many speech perception phenomena can be replicated in nonhuman primates. The perceptual abilities that monkeys demonstrate cannot be attributed to uniquely human speech processing mechanisms and may be due to more general auditory mechanisms. Conversely, perceptual tasks on which human listeners succeed and monkeys fail are good potential candidates for special-processing mechanisms in humans. Tests of duplex perception are valuable for theory construction because they provide a critical test of the two opposing models of the initial status of the mechanisms underlying speech processing in humans. In 1998 we conducted duplex perception tests with macaques, using synthetic /da/ and /ga/ syllables as stimuli. FUNDING NIH grants RR00166 and D C00520.
