[隋]曹宪的《博雅音》是一部反映公元6世纪末至7世纪初江淮地区语言状况的重要文献。本文拟对其音性质问题进行讨论,认为《博雅音》的音系基础是传统读书音而非当时的某一權威方言音,它所代表的应是6世纪末至7世纪初的金陵书音系统。 [Sui] Cao Xian's “Burson-Marstered” is an important document that reflects the language status of the Jianghuai region from the end of the 6th century to the beginning of the 7th century. This paper intends to discuss the nature of its tone, and concludes that the phonetic system of Burson-Marsteller is based on the traditional pronunciation rather than an authoritative dialect at that time, which should represent the Jinling pronunciation system from the late 6th century to the early 7th century .
