This study investigates anticipatory vowel-to-vowel coarticulation in Arabic, and seeks to determine the degree to which it is affected by the pharyngealization and length of intervening consonants. Speakers of Egyptian Arabic were recorded saying sentences containing nonsense sequences of the form /baɁabaCV:/, where C was chosen from {/t/, /tˤ/, /t:/, /tˤ:/} and V was a long vowel /i:/, /a:/ or /u:/. Analysis of the first and second formants of the recorded vowels revealed that (a) vowel-to-vowel coarticulatory effects could sometimes extend to a distance of three vowels before the context vowel; (b) the consonant-to-vowel effects associated with pharyngealization were consistently seen at similar distances, while also decreasing in magnitude at greater distances from the triggering consonant; and (c) effects related to intervening consonant length were idiosyncratic, and in particular did not lead to consistent blocking of vowel-to-vowel effects. In contrast, one speaker showed significant vowel-to-vowel effects at all three measured distances that were effectively blocked in the pharyngealized consonant condition.
本研究调查了阿拉伯语中的预期元音到元音协同发音，并试图确定其受中间辅音的咽化和长度影响的程度。录制了埃及阿拉伯语使用者说出包含形式为/baɁabaCV:/的无意义序列的句子，其中C选自{/t/，/tˤ/，/t:/，/tˤ:/}，V为长元音/i:/、/a:/或/u:/。对录制元音的第一和第二共振峰的分析表明：(a)元音到元音的协同发音效应有时可延伸至上下文元音前三个元音的距离；(b)与咽化相关的辅音到元音的效应在相似距离处始终可见，同时在距触发辅音更远的距离处幅度减小；(c)与中间辅音长度相关的效应是特异的，特别是不会导致元音到元音效应的一致阻断。相比之下，一名说话者在所有三个测量距离处都表现出显著的元音到元音效应，而在咽化辅音条件下这些效应被有效阻断。
