And why does it take them so long to begin speaking? Insights into these mysteries of human language acquisition are now coming from a surprising source: songbirds. Researchers who focus on infant language and those who specialize in birdsong have teamed up in a new study suggesting that learning the transitions between syllables—from “da” to “do” and “do” to “da”—is the crucial bottleneck between babbling and speaking. more
