1When visitors enter Planet Word,a museum in Washing⁃ton,D.C.,they will see Speaking Willow,a tall art piece repre⁃senting a tree.As they pass under the artwork,they can hear recordings of speech in hundreds of languages coming from the tree,most of which sound foreign to the listeners.The different voices also speak at the same time.The resulting noise is similar to that made in a crowded theater before a show begins.
