Now something you should know: there's no language which is always syllable timed or always stress timed.

没有一种语言总是以音节计时或者总是以重音计时。

Pro, pro, pro, one of the pro, one of the pro, one of the produ, before the voice slows down, takes more time on that up down shape of du, the stress syllable of producers.

Pro, pro, pro, 一个 pro，一个 pro，一个 produ，声音变慢之前，du 的上下形状需要更多时间，生产者的重读音节。
