Phonation stage (0-1 month)
• reflexive sounds, infants have no control
• Gooing and cooing stage (2-3 months)
• consonant-like and vowel-like sounds
• begin with /g/ and /k/, no need for precise manipulation of tongue, lips, or teeth
(if they have any)
• Expansion stage (4-6 months)
• more control over articulators
• manipulate loudness and pitch, play with sounds
• yell, growl, make raspberries, etc.
• Canonical babbling (6+ months) and variegated babbling (9+ months )
• true CV syllables
• canonical babbling: ma-ma, da-da
• reduplicative babbling: da-da-da-da
• variegated babbling: ba-di-ta
• jargon: babbling with melodic patterns (rhythm, stress, intonation)
• babblings are not referential, nor convey meaning
