人类识别元音的条件下进行了调查和感性识别的个别令牌声学特性相关。结果支持最近的研究结果，孤立的元音可能很容易识别的听众。实验提供的证据表明，某些反应任务会导致错误率膨胀。随后的实验表明，改进的识别在一个固定的扬声器上下文中，与随机扬声器相比，孤立的元音和门控中心。门控元音的表现更差，这表明动态特性（如持续时间和双元音化）补充了稳态线索。即使扬声器随机门控元音识别良好（14%的错误）。稳态信息（共振峰频率和fO），动态信息（共振峰斜率和持续时间）和扬声器信息（归一化）的措施。声学测量的判别分析表明元音类别之间的重叠相对较少。使用一种新的技术，用于相关的声学测量的个别令牌与识别的听众，它表明，识别性能是明确相关的声学特性;在固定扬声器的上下文中的改进与改进的统计分离共振峰归一化，门控元音;和动态信息是有关的识别差异之间的完整和门控孤立元音。
Conditions under which humans recognize vowels are investigated and perceptual identification of individual tokens to acoustic characteristics are related. Results support recent findings that isolated vowels may be readily identified by listeners. Experiments provided evidence that certain response tasks result in inflated error rates. Subsequent experiments showed improved identification in a fixed speaker context, compared with randomized speakers, for isolated vowels and gated centers. Performance was worse for gated vowels, suggesting that dynamic properties (such as duration and diphthongization) supplement steady-state cues. Even-speaker-randomized gated vowels were well identified (14% errors). Measures of steady-state information (formant frequencies and fO), dynamic information (formant slopes and duration), and speaker information (normalization) were adopted. Discriminant analyses of acoustic measurements indicated relatively little overlap between vowel categories. Using a new technique for relating acoustic measurements of individual tokens with identification by listeners, it is shown that identification performance is clearly related to acoustic characteristics; improvement in the fixed speaker context is correlated with improved statistical separation resulting from formant normalization, for the gated vowels; and dynamic information is related to identification differences between full and gated isolated vowels.
