本研究的目的是确定如何快速和一致的听众可以识别合成停止和元音，这取决于它们位于连接一个音素类的中心与下一个相邻音素类的中心的声学连续体的位置。所有刺激都是在斯德哥尔摩的皇家理工学院的OVE II上产生的;它们由（1）13个辅音-元音音节组成，其中第二和第三共振峰转换以产生/B、d、g/的方式变化，以及（2）13个元音，其中前三个共振峰以大约相等的对数步长变化到/i、b、g/。受试者被要求在一种条件下按下三个按钮中的一个，在另一种条件下做出适当的声音反应，从而从语音上识别每个刺激。对于塞音和元音，语音和按钮按压反应时间在音素中心附近比在音素边界附近低。在其他方面，塞音和元音的结果不同，支持塞音更容易识别的结论。这种差异是根据其他数据来看待的，这些数据显示了这两组信号的辨别函数的形状和水平的显著差异。[This这项研究得到了国家科学基金会的部分支持。
The purpose of this study was to determine how quickly and consistently listeners can identify synthetic stops and vowels, depending on where they lie on an acoustic continuum that connects the center of one phoneme class with the center of the next adjacent one. All stimuli were produced on OVE II at the Royal Institute of Technology in Stockholm; they consisted of (1) thirteen consonant‐vowel syllables in which the second‐ and third‐formant transitions varied in such a way as to produce /b,d,g/ and (2) thirteen vowels in which the first three formants varied in approximately equal log steps through /i,ɪ,ɛ/. Listeners were instructed to identify each stimulus phonemically by pressing one of three buttons in one condition and by making an appropriate vocal response in another. For both stops and vowels, voice and button‐press reaction times were lower near phoneme centers than in the vicinity of phoneme boundaries. In other respects, the results for stops and vowels differed, supporting the conclusion that the stops are the more readily identified. This difference is viewed in the light of other data that show gross differences in the shape and level of the discrimination functions for these two sets of signals.
