This study extends a cross-linguistic collaboration on phonological development, which aims at comparing production of word-initial sequences of consonant-vowel (CVs) across sets of languages which have comparable phonemes that differ in overall frequency. By comparing across languages, the influence of language-specific distributional patterns on phoneme mastery can be disentangled from the effects of more general phonetic constraints on development. We made word and non-word repetition experiments with French- and Drehu-acquiring 2-year-old to 5-year-old children. We first analysed production in words according to frequency data in French and Drehu. Results show that productions of word-initial consonants are correlated with frequency, especially in younger children. Then we compared the non-word production scores of French- and Drehu-acquiring children. French and Drehu learners have similar mean scores but show different patterns for specific phonemes that differ in frequency.
