486. 抹香鲸尾音中的元音和双元音频谱模式

from 知为谁 · host 知为谁

两份来源都聚焦于抹香鲸复杂的交流系统,特别是其咔哒声序列(称为“尾声”)中新发现的声学特性。第一份来源是一篇**《旧金山门》的新闻报道**,强调加州大学伯克利分校(UC Berkeley)的科学家,包括语言学家 Gasper Begus,通过 Project CETI(鲸目动物翻译计划)发现抹香鲸的尾声中存在类似于人类语言元音(如 /a/ 和 /i/)的声学模式。该报道指出,这一突破显示出鲸鱼的交流系统比之前认为的摩尔斯电码式的交流方式更为复杂,并引发了关于鲸鱼语言能力和权利的伦理和法律讨论。第二份来源是 Begus 及其同事在 PMC 上发表的同行评审科学论文摘要及节选,详细介绍了他们的研究发现,即尾声中存在元音样和双元音样的光谱模式。该论文采用声源-滤波器理论来类比人类元音发声与鲸鱼尾声,提出这些光谱特性(如共振峰及其轨迹)是独立于传统的咔哒声数量和时序之外的、可控且有意义的特征,极大地增强了抹香鲸交流系统的复杂性。内容来源:https://www.sfgate.com/bayarea/article/scientists-breakthrough-decoding-whales-21184413.phphttps://pmc.ncbi.nlm.nih.gov/articles/PMC12594577/
