我们研究了西班牙语中元音间无休止塞音的弱化，以深入了解元音间缓和的历史过程。在我们的语料库中，大约有三分之一的元音间/ptk/的所有标记在自发语音中完全或部分发声。然而，即使在全浊时，/ptk/往往比/bdg/表现出更大的收缩，软腭与唇音和齿冠相比差异较小。词首和词内部的音间段同样受到影响。基于我们的研究结果，从声学测量的相关性的音变，我们提出，共同的还原声音的变化，如声间辅音音变，开始作为全面的常规语音过程，同样影响所有目标在适当的语音环境。语音变化对词内部语境的共同限制可能是语音变化后期语音重新分类的结果。
We examine the weakening of intervocalic voiceless stops in Spanish in order to gain insight on historical processes of intervocalic lenition. In our corpus, about a third of all tokens of intervocalic /ptk/ are fully or partially voiced in spontaneous speech. However, even when fully voiced, /ptk/ tend to show greater constriction than /bdg/, with the velars being less different than labials and coronals. Wordinitial and word-internal intervocalic segments are equally affected. Based on our findings from acoustic measurements of correlates of lenition, we propose that common reductive sound changes, such as intervocalic consonant lenition, start as across-the-board conventionalized phonetic processes equally affecting all targets in the appropriate phonetic context. The common restriction of the sound change to word-internal contexts may be a consequence of phonological recategorization at a later stage in the sound change.
