Kong Chao, a 2022 doctoral candidate in our school (supervisor Professor Zhang Shuzheng), published a paper An acoustic study on age-related in Volume 104 of the top journal of humanities and social sciences Journal of Phonetics in May 2024 changes in vowel production of Chinese ("Acoustic study of age-related Chinese vowel production")。Kong Chao is the first author of this article，Professor Liu Juan of our college is the corresponding author，School of Liberal Arts of Shandong University is the first unit。
As age increases，How will the nature of human bet365 games best slotsspeech pronunciation change，This is an issue that has received widespread attention in the phonetics community in the past century，In the context of the current era of increasing population aging，This research field has important theoretical significance and application value at the same time。In this field of research，How will the vowel pronunciation of the elderly change，The reasons for this change have been widely debated in research in recent decades，The academic community has not been able to reach a unanimous conclusion。In response to this problem，Kong Chao first proposed a mathematical method to estimate the physiological properties of the speaker's vocal tract based on acoustic methods，In conjunction with advanced statistical solutions，Using large-scale voice materials collected first-hand from 115 native bet365 games best slotsChinese speakers，Conducted a systematic study on a series of widely controversial issues in this field。Research confirms that older people have longer vowel duration and a tendency to centralize、The aging process has age differences and nonlinear characteristics, which have been widely discussed in academic circles for decades but failed to reach a unanimous conclusion，And pointed out that the inconsistent conclusions of previous relevant studies mainly come from several flaws in statistical methods and experimental plans。At the same time，The study also found for the first time that there is a critical transition period in the language aging process of men at the age of 40-50，Men will experience extremely rapid aging of speech production ability around the age of 50。In addition，This study is the first to use large sample data to falsify the hypothesis bet365 online casinothat "vocal tract length will increase with age and affect the pronunciation of the elderly", which has been widely discussed in the academic community。
This research solves many issues that have been widely debated in this research field in recent decades，And provides a very important methodological reference for future research in this field，Evaluated by the reviewer as "making a very important contribution to this field" (quoted from Reviewer #2)。In addition，This research is of great significance for medical and anatomical research as well as pathological screening and rehabilitation treatment of elderly language ability，Has considerable application value and social value，The reviewer believes that this type of research "is very lacking in linguistics" (quoted from Reviewer #1)。
