Answer:
infant direct speech
Explanation:
Infant direct speech is the language or the speech pattern a person uses when communicating with an infant.
Generally the people talk in a melodic way and is slower than people normally speak. The words are also articulated more than what is considered normal.
The degree to which an adult uses infant direct speech depends on the age of the infant. The younger the infant is the more stress is given while using infant direct speech and vice versa.
