Other parameters come into play, such as prosody, which includes pauses, accentuation and intonation.

This juxtaposition is far from coincidental, as the researchers' experiments revealed that dog brains respond in the same positive ways to exaggerated prosody as our very own infants.

If a brain-computer interface could re-create someone’s speech with the inherent prosody and emotional weight found in music, it could reconstruct far more than just words.

Linguists call this language feature “prosody,” something machines have had a hard time mastering.

Spencer showed a wonderful sense of prosody and storytelling in “I Know My Soul,” and Thompson sounded an exultant, if sometimes strident, call to celebration in “My People.”
