When as young as 18 weeks old, Dr. Patricia Kuhl found that babies can listen to “ah” and “ee” vowel sounds and gaze at the correct, corresponding lip shape on a video monitor.
Around age 2-3 months, infants start coping and making soft vowel sounds. They are able to do this because their larynxes and other parts of their throats change to allow these sounds.
By age 3-4 months, babies begin to make consonant sounds of b, k, m, g, and p.
By 4-5 months, the vowels and consonants are put together to form nonsense words.
