Strange [J. Acoust. Soc. Am. 85, 2135-2153 (1989b)] has demonstrated that there is sufficient information in the onsets and offsets of syllables, spoken in sentence context, to provide accurate identification of the vowel in the syllable. Verbrugge and Rakerd [Language Speech 29, 39-57 (1986)] and Andruski and Nearey [J. Acoust. Soc. Am. 91, 390-490 (1992)] have shown that such information is present in citation-form syllables even when the syllables begin with one speaker and end with another. These studies of "hybrid syllables," however, reported relatively high error rates. In a perceptual experiment using /dVd/ syllables spoken in sentence context by a male and a female speaker, relatively low error rates were obtained for both "silent-center" syllables and "hybrid silent-center" syllables. It was concluded that the information specified over syllable onsets and offsets together for identification of vowels is speaker independent and that it was sufficient in most cases to specify the vowel. The acoustic patterns, represented as functions of log (F2/F1) over time, revealed potentially useful dynamic acoustic characteristics of co-articulated vowels.
斯特兰奇[《美国声学学会杂志》85, 2135 - 2153 (1989b)]已经证明，在句子语境中说出的音节的起始和结束部分存在足够的信息，足以准确识别音节中的元音。韦尔布鲁格和拉克德[《语言与言语》29, 39 - 57 (1986)]以及安德鲁斯基和尼尔里[《美国声学学会杂志》91, 390 - 490 (1992)]已经表明，即使音节由一个说话者开始而由另一个说话者结束，这种信息在引用形式的音节中也存在。然而，这些关于“混合音节”的研究报告的错误率相对较高。在一项感知实验中，使用男性和女性说话者在句子语境中说出的/dVd/音节，对于“无声中心”音节和“混合无声中心”音节都获得了相对较低的错误率。得出的结论是，为识别元音而在音节起始和结束部分共同指定的信息与说话者无关，并且在大多数情况下足以确定元音。作为log (F2/F1)随时间变化的函数表示的声学模式揭示了协同发音元音潜在有用的动态声学特征。
