Raj is a 6-month-old infant who has recently begun experimenting with different sounds. His parents notice that he now produces a variety of vowels and consonants such as 'ba', 'da', 'ma', and 'ga'. These sounds usually come out as single consonant-vowel combinations, and he repeats them joyfully while playing. Although Raj is very expressive, he has not yet formed meaningful words. Instead, he seems to be exploring how to coordinate his tongue, lips, and voice to make new sounds. At which stage of language acquisition is Raj?
