摘要
文章从静态和动态两个角度探讨英语语音的模糊性。首先，以音素为切入点，发现根据声腔的开放和封闭基本可以把元音和辅音分清楚，但由于声腔的开放大小没有明确的界限，实际上所获得的是近似的模糊音；接着以音位为切入点，从音位变体，非音质音位等方面来考察，发现语音的社会性促成音位变体间的模糊界限；再以语流音变为切入点，从同化、异化等五种语流音变现象中，发现相邻音彼此间相互影响以及语速的快慢、声音的高低、强弱导致语音模糊性。
The probe into phonetic fuzziness has been made from the static and dynamic angles. Attention has first been given to phones and it has been found that based on the opening and closing of sound cavity, vowels and consonants can be clearly distinguished from each other. However, what we have actually achieved is the approximate fuzzy sounds because of no clear distinction in cavity opening. Phoneme has been made as a second cut-in point and observation has been made on allophones and non-tone phonemes, which has led to find that the social properties of phonetics has resulted in the fuzzy demarcation existing in allophones. From the phenomena in sound-changes in 5 phonetic context such as assimilation and dissimilation and the like, adjacent sounds can affect each other and the speaking rate, sound in pitch and low, strong and weak can lead to phonetic fuzziness.
