双语者用每种语言产生音素的方式为了解双语音系空间的本质提供了一个窗口。 对于停音辅音，如果其语言在发声开始时间 (VOT) 区别方面不同的早期连续双语者在每种语言中产生类似母语的 VOT，则意味着他们已经开发出单独的第一语言和第二语言音素，这是针对停音区别的语言特定的语音实现。 鉴于希腊语浊音停音的模糊音系状态已引起争议，但尚未进行调查实验性的希腊语-英语双语者可以在这个问题上提供独特的视角。 我们首先记录了希腊语和澳大利亚英语单语者的语音，以观察每种语言中词首和词中（后声音和后鼻音）位置中 /p t b d/ 的母语 VOT。希腊语单语者，而英语语境中的双语者在初始位置上与澳大利亚英语单语者的 VOT 相匹配，但在语音上更复杂的中间位置上显示出一些适度的差异。我们将这些结果解释为双语者拥有针对每种语言特定的浊音和清音塞音的语音类别的证据，但在第二语言中与在第一语言中受位置上下文的影响不同 (C) 2010 Elsevier Ltd 保留所有权利
The way that bilinguals produce phones in each of their languages provides a window into the nature of the bilingual phonological space For stop consonants if early sequential bilinguals whose languages differ in voice onset time (VOT) distinctions produce native-like VOTs in each of their languages it would imply that they have developed separate first and second language phones that is language-specific phonetic realisations for stop-voicing distinctions Given the ambiguous phonological status of Greek voiced stops which has been debated but not investigated experimentally Greek-English bilinguals can offer a unique perspective on this issue We first recorded the speech of Greek and Australian-English monolinguals to observe native VOTs in each language for /p t b d/ in word-initial and word-medial (post vocalic and post-nasal) positions We then recorded fluent early Greek-Australian-English bilinguals in either a Greek or English language context all communication occurred in only one language The bilinguals in the Greek context were indistinguishable from the Greek monolinguals whereas the bilinguals in the English context matched the VOTs of the Australian-English monolinguals in initial position but showed some modest differences from them in the phonetically more complex medial positions We interpret these results as evidence that bilingual speakers possess phonetic categories for voiced versus voiceless stops that are specific to each language but are influenced by positional context differently in their second than in their first language (C) 2010 Elsevier Ltd All rights reserved
