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.

Dr. Patricia K. Kuhl found that the babies' brains are most open to learning the consonants in their native language at <u>nine months old</u> and vowels at <u>six months old</u>.
Explanation:
Dr. Patricia Kuhl identified that babies, <em>at six months of age, have a great capacity for learning even two languages while allowing them to analyze the correct intonation and accent of them</em>, although between three and five months the babies can capture the sound of some vowels or even consonants, her study showed <u>that at six months it is the ideal age to learn vowels of one or two languages and that at nine months it is in perfect condition to learn consonants in general</u>.
