Cleft Speech & Language Study

The Cleft Collective Speech and Language Study (CC SL) is working in partnership with the Cleft Collective Cohort Studies – a large scale national study of children born with cleft lip palate.  To find out more about the main study visit the home page



The aim of the CC SL study is to create a resource for the study of the early speech and language development of children born with cleft palate.



Why is this important?

Although clefts are generally repaired within the first year of life in the UK, and some affected children develop typical speech patterns, there is evidence that more than 50% of children born with a cleft palate require SLT intervention at some point.  A review of speech outcomes from the Cleft Speech Audit Group found that 19% of 5-year-olds and 4% of 12-year-olds were judged to be impossible to understand or only just intelligible to strangers.

How can I get involved?

If you want to know more about the study, you could talk to your local cleft center speech and language therapy team if you are based in the UK, or you can contact Dr Yvonne Wren, principal investigator for the CC SL study
