The generality of the pattern of progressively greater lengthening within the utterance-final syllable, previously found with respect to final stops, is shown to extend to syllables in Hebrew with final fricatives. Seven native speakers of Hebrew read matched sentence pairs in which bisyllabic key words appeared in non-final and sentence-final position. Final fricatives showed almost four times as much utterance-final lengthening as the preceding stressed vowel. Final lengthening affected the duration of each segment of the final syllable, and also extended to the initial unstressed syllable of the final word. Though final fricatives showed more lengthening in sentence-final position than final-stop closures, no difference was found in the lengthening of the vowels preceding these consonants. The greater lengthening of the final fricative relative to the preceding vowel resulted in C/V ratios which failed to distinguish between the voiceless fricative in non-final position and the voiced fricative in utterance-final position. These results suggest that sentence position is taken into account in the perception of voicing, such that the C/V ratio applicable in non-final position is increased by a factor of two in final position.
先前在词末塞音方面发现的词末音节内逐渐延长的一般模式，被证明也适用于希伯来语中以擦音结尾的音节。七名希伯来语母语者朗读了匹配的句子对，其中双音节关键词出现在非句末和句末位置。词末擦音的词末延长几乎是前一个重读音节的四倍。词末延长影响了词末音节每个音段的时长，并且还延伸到了词末单词的首非重读音节。尽管词末擦音在句末位置的延长比词末塞音闭塞更多，但在这些辅音之前的元音延长方面未发现差异。相对于前一个元音，词末擦音的更大延长导致C/V比率无法区分非句末位置的清擦音和句末位置的浊擦音。这些结果表明，在语音感知中会考虑句子位置，使得在非句末位置适用的C/V比率在句末位置增加了两倍。
