模因机制下人类元音系统演化的计算模型

Computation model of human vowel system evolution based on meme

人类元音系统的演化具有明显的普遍规律,元音系统的演化研究是人类智能演化问题的重要分支,在国外已成为人工社会和语言学等研究领域的热点问题,目前在国内鲜有文献报道。本文分析了现有的人类元音系统演化模型,阐述了模因理论与文化进化,提取了独立于具体语言的元音声学特征——共振峰,构造了由元音舌位圆唇度编码生成元音共振峰值的插值函数,提出了基于模因论的具有"纵向"结构(传承)和"横向"结构(传播)融合特征的人类元音系统演化规律计算模型。仿真实验表明:该模型从宏观和微观两个层面刻画出了人类元音系统演化的普遍规律。

The human vowel system shows a remarkable universal rule.The research on human vowel system evolution and its computation is both part of a larger research effort into understanding the nature of intelligence,and an important issue in life and linguistics research areas.There is almost no literature to our knowledge in our country,whereas research has become a hotspot abroad.First,the weakness of an existing human vowel system evolutionary model was analyzed.Then,meme theory and cultural evolution were described.Sequentially,vowel formants independent of specific language were given and synthesis function from vowel＇s tongue position and lip roundness to vowel formants was constructed.Finally,a computational model blending vertical structure（inheritance） and horizontal structure（communication） for a human vowel system evolution was brought forward based on meme theory.Simulation experimental results indicated the effectiveness, illustrated the universal and the rule of the human vowel system from both macro and micro levels.
