五组母语为日语的听众被分配到五种不同的词汇外部语境中。在完整条件下，三种类型的目标双音节/mVmV/、/mV:mV/和/mVmV:/以两种语速在载体句中发音。在其他四种情况下，从原载体句中删除完整条件下的目标双音节（切除）；嵌入在载体句中的其他比率（错配）；只呈现前三个音节（previous），只呈现后三个音节（following）。在完整和不匹配条件下，识别词类型的准确率高于切除和不匹配条件，这表明以适当的比率出现载体句对准确识别很重要。还发现，前面或下面的短语都包含了足够的信息来识别词的类型。此外，前面和后面的短语对目标的第一和第二个元音都有影响，这表明距离目标两个以上音素的远端言语材料会影响识别的准确性。根据率归一化的邻接原则讨论了其含义。版权所有(c) 2004 S.

Five groups of native Japanese listeners were assigned to five conditions differing in word-external contexts. In the Intact condition, three types of target disyllables, /mVmV/, /mV:mV/, and /mVmV:/ were spoken in a carrier sentence at two speaking rates. In the other four conditions, the target disyllables of the Intact condition were excised from the original carrier sentence ( Excised); embedded in the carrier sentence of the other rate ( Mismatch); presented only with the preceding three syllables ( Preceding), and presented only with the following three syllables ( Following). The accuracy for identifying the word types was higher for the Intact than Excised and Mismatch conditions, indicating that the presence of the carrier sentence with an appropriate rate was important for accurate identification. It was also found that either the preceding or the following short phrase contained sufficient information for identifying the word types. Further, there were effects of the preceding and following phrases on both the first and second vowels of the targets, suggesting that the distant speech materials more than two phonemes away from a target in both sides can affect identification accuracy. Implications are discussed in terms of the adjacency principle for rate normalization. Copyright (c) 2004 S. Karger AG, Basel.
