Human Speech

You've heard parrots parrot human [speech:talk] . But what about this? That strange kazooing sound is from a whale. It's a captive beluga whale named NOC. And researchers say it's his attempt to mimic the sound of [humans:humours] talking. Back in 1984 a diver at the National [Marine:naval] Mammal Foundation surfaced from the whale tank, and said, "Who told me to get out?" Turns out, no one did. Well, no human did. The "out" [sound:noise] came from NOC the whale. When the researchers compared recordings of NOC to human speech, they found that the rhythm of his utterings indeed [matched:paired] that of humans. So did the pitch, at [several:reveal] octaves lower than the whales' usual clicks and whistles.
