本研究旨在探讨美国手语中的一种语音弱化形式。语音还原发生在正常的语言产生过程中，当语言使用者产生一个不太清晰的表达形式，而不是产生一个仔细表达的单词形式时。当本族语者在语境中产生符号时，它们往往不同于符号的引用形式。在某些情况下，语音减少表现为在比引用形式更低的位置产生的符号。之前已经有文献记录了符号降低，但这是第一次研究语音细节。这里呈现的数据是由六个本地签名者在两个语音环境中以三个签名率产生的WONDER符号的令牌，这些签名率是由光电运动捕获捕获的。结果表明，所有的签名者，根据我们操纵的因素，符号降低发生。符号的产生受到几个语音因素的影响，这些语音因素也会影响语音的产生，即产生速度、语音语境和话语中的位置。此外，我们还发现了手势产生的有趣变化，这可能是手势风格的区别的基础，类似于语音中的口音或音质。
This study examines sign lowering as a form of phonetic reduction in American Sign Language. Phonetic reduction occurs in the course of normal language production, when instead of producing a carefully articulated form of a word, the language user produces a less clearly articulated form. When signs are produced in context by native signers, they often differ from the citation forms of signs. In some cases, phonetic reduction is manifested as a sign being produced at a lower location than in the citation form. Sign lowering has been documented previously, but this is the first study to examine it in phonetic detail. The data presented here are tokens of the sign WONDER, as produced by six native signers, in two phonetic contexts and at three signing rates, which were captured by optoelectronic motion capture. The results indicate that sign lowering occurred for all signers, according to the factors we manipulated. Sign production was affected by several phonetic factors that also influence speech production, namely, production rate, phonetic context, and position within an utterance. In addition, we have discovered interesting variations in sign production, which could underlie distinctions in signing style, analogous to accent or voice quality in speech.
