Speech-language pathologists frequently use data regarding children's speech acquisition.
The table below includes journal articles and theses that provide data on the age typically developing children acquire consonants, consonant clusters, vowels, and tones. Inclusion in the table does not indicate endorsement or guarantee the rigor of the research.
In addition to the list below, the Speech acquisition summary page provides an overview of speech acquisition across languages. The CHILDES/BIB is a bibliography of research articles published before 2002 on child language acquisition (including phonological acquisition). If you know of additional studies regarding the age of acquisition of consonants, consonant clusters, vowels, or tones please contact us.
