Climate Change May Shape Languages Too

Researchers have determined that languages with a wide range of tone pitches are more prevalent in regions with high humidity levels while languages with simpler tone pitches are mainly found in drier regions.

They explain this by noting that the vocal folds require a humid environment to produce the right tone. That means climate and weather our voices too.
