GENETIC AND EXPERIENTIAL INFLUENCES ON THE DEVELOPMENT OF PRIMATE VOCAL BEHAVIOR

该项目的重点是在声乐沟通的性别差异， 成年期和发育期，关于个人经验在 成人声乐技能的获得，以及 用于声学参数提取和分析的计算机算法。 今年的主要发现是： 自动提取声学参数并在此进行细化 实验室的婴儿恒河猴的发声被用来 分析婴儿时期最突出的呼唤的发展， 社会分离时期。 这些分析表明， 声学参数的数量随发育而变化。 一些参数 遵循一个有规律的成年人价值观的轨迹，而其他人则会改变 而突然转向更像成人的价值观。 识别各个 根据婴儿叫声结构的差异， 即使在新生儿时期也要完成。 "属性 假设“（纽曼和Goedeking，1992年）得到了一项研究的支持， 绒猴的发声行为，其中单独的声学参数编码 背景和性别。

This project focuses on gender differences in vocal communication in adulthood and during development, on the role of individual experience in the acquisition of adult vocal skills, and on the development of computer-based algorithms for acoustic parameter extraction and analysis. Major findings this year were: A computer program developed for automatic extraction of acoustic parameters and refined in this laboratory for the vocalizations of infant rhesus macaques was used to analyze the development of the most prominent infant call given during periods of social separation. These analyses revealed that a large number of acoustic parameters change with development. Some parameters follow a regular trajectory toward adult values, while others change rather abruptly to more adult-like values. Identification of individual infants on the basis of differences in the structure of their calls can be accomplished even during the neonatal period. The 'attribute hypothesis' (Newman and Goedeking, 1992) was supported by a study of marmoset vocal behavior, wherein separate acoustic parameters encoded context and gender.
