Babbling Is Necessary for Speech and Language Development

What is the importance of pre-linguistic vocalization?

Background: The characterization and significance of pre-linguistic vocalization has long been the subject of research and debate. Pre-linguistic vocalization can generally be classified into non-speech-like vocalizations, including vegetative sounds, and speech-like vocalizations known as protophones. Most protophones begin with vowel-like vocalizations and culminate in well-formed, reduplicated consonant-vowel combinations referred to as canonical babbling.
