Speech & Development
Speech and Language are often used interchangeably, which is incorrect. There is a difference between the two. Speech is the ability of humans to produce specific sounds to communicate with other humans. Language is a set of well-accepted rules created by humans to express their thoughts and emotions to others so that they are understood. Language includes talking, writing, and using sign language. Speech allows a person to orally express language.
Infants start communicating in the early days of their lives. They learn how to make sounds like crying, cooing and gurgling. They realize that certain sounds will get them what they want. For example, they learn that crying will get them food and comfort. At this point they also start making sense of and recognizing certain specific sounds like their mother's voice. As they grow older, they are able to recognize speech sounds (phonemes) that make up words of their mother tongue.
As the jaw, lips, tongue, and voice develop, a child is able to convert unintelligible babbling sounds into more controlled ones.
