本研究探讨西安达卢西亚西班牙语中/s/ +无辅音塞音序列中的后送气无辅音塞音现象。先前的分析已经提出,后吸气通过重组的声门扩展手势/s/和口头收缩手势的停止。这一理论通过稳步提高说话者的生产率来检验,这已被证明会引发言语和其他运动活动中手势组织的自发变化。研究结果支持了最初的假设。随着速率的增加,从具有预抽吸和短VOT的生产切换到具有长VOT的生产。此外,VOT和闭合前抽吸之间存在权衡,表明它们可能由相同的手势引起。最后,生产的可变性显示了人类协调阶段转变的一些标志。总之,手势组织的变化为这种方言中的后送气塞音提供了一个简单的解释。
This study examines the phenomenon of post-aspirated voiceless stops in Western Andalusian Spanish in /s/ + voiceless stop sequences. Previous analyses have proposed that the post-aspiration arises through a reorganization of the glottal spreading gesture for /s/ and the oral constriction gesture for the stop. This theory is tested by steadily increasing speakers’ production rate, which has been shown to trigger spontaneous changes in gestural organization in speech and other motor activities. Results from the study support the initial hypothesis. There is a switch from productions with with preaspiration and short VOT to those with long VOT as rate increases. Additionally, there is a tradeoff between VOT and pre-closure aspiration, indicating they may result from the same gesture. Lastly, the variability in production shows a number of hallmarks of phase transitions in human coordination. In sum, a change in gestural organization provides a simple explanation for post-aspirated stops in this dialect.
