Dolphins speak "baby talk" to offspring
Have you ever noticed that when adults speak to babies or small children, they speak in a distinctively specific manner? As if by instinct, they speak in a high-pitched voice, with clear pronunciation and longer pauses between words.
It seems that this “baby talk” is not reserved for humans. Researchers have discovered that dolphins too indulge in baby talk—by changing their characteristic whistles and frequencies—when they communicate with their offspring.
