This paper presents evidence against the existence of sonority-driven stress in Gujarati. Gujarati is one of the clearest and most revealing cases of sonority-driven stress with distinctions among peripheral vowels. A production experiment was performed to determine the accuracy of the claim that [a] attracts stress away from the default position. Of the five types of phonetic evidence examined, only F1 provides clear evidence for stress, revealing stress to be consistently penultimate, and not sonority-driven. As Gujarati is one of the core cases of sonority-driven stress, this finding challenges the claim that it exists. However, this paper does not exclude the possibility that stress may avoid schwa (or central vowels), as reported for several languages. Theoretical and methodological implications are discussed, particularly for theories that have a ‘symmetric effect’ and for descriptions that are impressionistic.

关于古吉拉特语中响度驱动压力的存在

本文提出了反对古吉拉特语存在响度驱动压力的证据。古吉拉特语是响度驱动压力的最清晰和最有启发性的案例之一，外围元音之间存在区别。进行了生产实验以确定 [a] 将压力从默认位置吸引开的说法的准确性。在检查的五种语音证据中，只有 F1 为重音提供了明确的证据，表明重音始终是倒数第二的，而不是由响度驱动的。由于古吉拉特语是响亮驱动压力的核心案例之一，这一发现挑战了它存在的说法。然而，本文不排除重音可能避免使用 schwa（或中心元音）的可能性，正如几种语言所报道的那样。讨论了理论和方法学意义，
