voice 2: Professor Roy plans to record his son until he is three years old. A healthy human baby can usually speak his first language by this age.
声音2：罗伊教授计划让记录的时间一直持续到他儿子三岁。健康的人类婴儿通常在这一年龄段会说母语。

voice 1: Language is an important part of every person's life. Without language, people could not communicate with each other. So, Professor Roy's work with language is very valuable. Success in the Human Speechome Project could lead to better treatment for people who have trouble learning language. Or it could lead to computer programs that can learn to speak.
声音1：语言是所有人生活的重要组成部分。没有语言，人们就无法互相交流。因此，罗伊教授进行的语言研究非常有价值。人类家庭语言计划的成功可以更好地治疗那些学习语言有困难的人。或是设计出可以学会说话的计算机程序。
