babble

Similar to us, birds learn to sing by mimicking the adults, and the early chirps are akin to a baby's babble.

和人类一样，鸟类通过模仿长者学习鸣叫，最开始鸣叫时类似于婴儿的牙牙学语。

If your child often has a pacifier in his mouth, he may be less likely to babble and practice talking, or the pacifier may distort his speech.

如果你的宝宝经常含着奶嘴，那这样可能会减少宝宝牙牙学语，练习说话的机会，或者奶嘴可能会搅乱他的言语发展。
