本文讨论了有时出现在塔什希伊特柏柏尔语辅音之间的弱读音，并试图确定它们来自哪里。基于单词开头的C1C2簇的声学数据，我们研究了喉规范、发音方式和辅音在簇中发音位置的顺序如何影响它们的分布和持续时间特征。结果表明，它们在声学中只可能出现在特定的辅音上下文中，并且在一定的手势协调条件下。具体来说，要使这些问题浮出水面，必须满足两个条件。首先，这个序列中至少有一个辅音应该是浊音，因为它们不会出现在单词开头的不浊音集群中。其次，在从一种辅音结构到另一种辅音结构的转换过程中，声道必须足够开放。因此，它们在停止-停止集群的第一个辅音的释放和最小重叠的序列中最常见。此外，根据说话者和集群类型的不同，语音的持续时间也有所不同，但有或没有语音的集群的时间长度基本上是无法区分的。综上所述，这些结果表明，Tashlhiyt中的弱读音元素是与语音实现相关因素的结果。
This paper deals with schwa elements that sometimes occur between consonants in Tashlhiyt Berber and seeks to determine where they come from. Based on acoustic data on word-initial C1C2 clusters, we examine how laryngeal specifications, manner of articulation and ordering of the place of articulation of the consonants in the cluster may govern their distribution and their durational characteristics. Results show that their occurrence in the acoustics is only possible in specific consonantal contexts, and under certain conditions of gestural coordination. Specifically, two conditions should be met for these schwas to surface. First, at least one of the consonants in the sequence should be voiced, as they never occur in word initial voiceless clusters. Second, the vocal tract has to be sufficiently open during the transition from one consonant configuration to the other. They are therefore most frequent at the release of the first consonant of stop-stop clusters and in sequences with minimal overlap. In addition, schwas are found to have variable durations depending on speaker and cluster type, but the temporal lengths of clusters with or without them are essentially indistinguishable. Taken together, these results suggest that schwa elements in Tashlhiyt emerge as a consequence of factors linked to phonetic implementation.
