A new study finds evidence for the "talk-alone-effect" in adults who stutter. When they're alone and think no one's listening, they don't stutter at all.

Fine aerosols generated from talking and singing contain more viral particles than coarse aerosols, research finds.

New research finds that songbirds use patterns similar to those in human speech. Like humans, birds tend to use shorter pieces when making larger phrases.

Engineers have created a tiny, wireless implant to rapidly change the pitch of adult songbirds' songs. The goal is to better understand human speech.

"Before infants are even producing words, our findings indicate that the conversations we have with infants matter for their brain function."

The way we talk reveals a lot about us, the author of a new book argues. But biases against certain kinds of speech are easy to pass to kids, she says.

While grooming each other, chimpanzees move their mouths at a rate similar to human speech. It's another clue in the mystery of speech's evolution.

The top five automated speech recognition systems—used by employers and courts—make double the errors when black speakers use them, research finds.

Asking people to retell a story soon after stroke can show how language links to parts of the brain, say researchers. The study may lead to new therapies.
