  However, studies testing young children’s abilities to cope with accent-related variation in the speech signal have generated mixed results, with some work emphasizing toddlers’ early competence and other work focusing more on their long-lasting difficulties in this domain.

• A longitudinal case study on the development of consonant–vowel distribution in the babbling of a Czech–English infant (2022) · doi

  Previous studies have shown that bilingual infants adjust the distribution of vowels and consonants, while babbling, to the languages they are exposed to, but little is known about the developmental trajectory of this skill.

• Developmental shift in the discrimination of vowel contrasts in bilingual infants: is the distributional account all there is to it? (2009) · doi

  A shift from language-general to language-specific sound discrimination abilities has been largely attested in different populations of infants during the second half of the first year of life; however, data are still scarce regarding bilingual populations.
