The specific tone of voice used when speaking to infants, babies, toddlers, and small pets is technically called "motherese." It is characterized by a higher pitch, exaggerated intonation, and slower, clearer speech patterns. It is thought to be a way of capturing the attention and interest of the listener, as well as facilitating language learning and development. The terms "baby talk" and "child-speak" are commonly used to refer to this style of communication, but they are more general and less precise than the term "motherese." "Telegraphic speech," on the other hand, refers to the simplified, short phrases that young children often use when first learning to speak.
