Childhood Language Development

“The development of speech production throughout an individual's life starts from an infant's first babble and is transformed into fully developed speech by the age of five.^[7] ”

The first stage of speech doesn't occur until around age one (holophrastic phase).

Between the ages of one and a half and two and a half the infant can produce short sentences (telegraphic phase).

After two and a half years the infant develops systems of lemmas used in speech production.

Around four or five the child's lemmas are largely increased; this enhances the child's production of correct speech and they can now produce speech like an adult.

An adult now develops speech in four stages: Activation of lexical concepts, select lemmas needed, morphologically and phonologically encode speech, and the word is phonetically encoded.^[7]
