摘　　要：文章以美国总统奥巴马的就职演说及其他VOA节目的录音为语料,对美国英语语流中词首[s]后的清音[p],[t],[k]的音变进行了声学分析。声谱图分析表明:美国英语语流中词首[s]后的[p],[t],[k]在爆破之前声带并没有振动,爆破之时即出现元音共振峰纹样和基频曲线。声学分析表明美国英语语流中词首[s]后的[p],[t],[k]是非送气的清音,不是浊音。Using the recording materials from VOA, like president Obama＇s inaugural address and other programs as the object, this thesis aims at the analysis of sonantization of surds in the linguistic situation of initial [ S] ＋ [ p] or [ t] or [ k] in American English. A- nalysis from spectrograms shows that the vocal cords do not vibrate before explosion, and the formant patterns or curves of fundamental frequency appear immediately after explosion. This acoustic analysis shows that in American English, the linguistic situation of initial [ S] ＋ [p]or It] or [k] does not sonantize [p], [t] and [k] at all, nevertheless, [p], [t] and [k] in this situation become unaspirated.
