大多数英语前缀是音节，也可以开始的话，他们不作为一个生产前缀的功能。文献指出了发音上的差异，例如真前缀，例如discolour中的/d s/，比伪前缀，例如discover中的/d s/有更重的节奏节拍。当dis-或mis-后面的音节以一个无音节的塞音开始时，其VOT有明显的差异，但dis/mis本身的差异更为微妙，尚未被系统地测量。五个英国南部英语的发言者参与了40个脚本对话，这些对话在受控的语音环境中包含这些单词。与假前缀词相比，前缀词在音节2的清化起始处更长，并且具有更长且更外围的[]、更长的VOT和更短的[s]。这些差异产生了与感知节拍差异一致的独特声学模式。由于核/postnuclear口音和词频的影响进行了观察，但似乎是次要的形态状态的影响。我们的结论是，这些音节的形态状态是其特征的声学模式的主要原因，他们的音段组成决定了进一步减少过程中，他们可能会经历由于较弱的韵律背景，较高的词频，休闲寄存器，和其他影响。
Most English prefixes are syllables that can also begin words in which they do not function as a productive prefix. The literature notes a pronunciation difference such that true-prefixes, e.g. /dɪs/ in discolour, have a heavier rhythmic beat than pseudo-prefixes, e.g. /dɪs/ in discover. When the syllable following dis- or mis- begins with a voiceless stop, there is a clear difference in its VOT, but differences in dis/mis itself are more subtle and have not been systematically measured. Five speakers of Southern British English engaged in 40 scripted dialogues which contained such words in controlled phonetic contexts. Prefixed words were longer up to voicing onset in syllable 2 and had longer and more peripheral [ɪ], longer VOT, and shorter [s] than pseudo-prefixed words. These differences produced distinctive acoustic patterns consistent with the difference in perceived beat. Effects due to nuclear/postnuclear accent and word frequency were observed, but appear to be secondary to effects of morphological status. We conclude that the morphological status of these syllables is the primary cause of their characteristic acoustic patterns, and that their segmental composition dictates further reduction processes they may undergo due to weaker prosodic contexts, higher word frequency, casual register, and other influences.
