Can We Do an Episode on Tone?

Robert: Can you guys do an episode on tone? I've studied English, German, French, Czech, Japanese and Korean. He can almost hear them, but he can never produce them with any degree of fluency. There are a lot of languages that have the two or three tone systems that might be a little bit easier for you to understand. Navajo has a two tone system. On YouTube, there are some videos where people do things like give the weather report in Navajo. Yoruba is the classic example of a three tone system.
