当一系列合成的塞音子音的成员在第三共振峰（F3）特征上变化并且在感知上从/da/到/ga/变化时，人类听者报告说听到的/ga/音节比系列成员在/ar/之前时听到的更多。有人建议，这种转变的识别是专门的过程，补偿声学后果的协同发音的结果。为了避免这种感知现象的物种特异性，在一个音节“标记”任务中收集了非人类动物的数据。本研究训练了4只日本鹌鹑（Coturnix coturnix japonica）不同地啄一个键来识别清晰的/da/和/ga/样本。训练后，a /da/-/ga/系列的歧义成员在/al/和/ar/音节的上下文中呈现。啄食行为表现出了与人类数据相一致的转变。这些结果表明，潜在的“感知补偿coarticulation”的过程是物种普遍的。此外，所表达的反应行为模式在感知系统中相当常见。(C)1997年美国声学学会。
When members of a series of synthesized stop consonants varying in third-formant (F3) characteristics and varying perceptually from /da/ to /ga/ are preceded by /al/, human listeners report hearing more /ga/ syllables than when the members of the series are preceded by /ar/. It has been suggested that this shift in identification is the result of specialized processes that compensate for acoustic consequences of coarticulation. To lest the species-specificity of this perceptual phenomenon, data were collected from nonhuman animals in a syllable ''labeling'' task. Four Japanese quail (Coturnix coturnix japonica) were trained to peck a key differentially to identify clear /da/ and /ga/ exemplars. After training, ambiguous members of a /da/-/ga/ series were presented in the context of /al/ and /ar/ syllables. Pecking performance demonstrated a shift which coincided with data from humans. These results suggest that processes underlying ''perceptual compensation for coarticulation'' are species-general. In addition, the pattern of response behavior expressed is rather common across perceptual systems. (C) 1997 Acoustical Society of America.
