Longitudinal Leicester Corpus  It has been suggested that
children's learning and accuracy of speech sounds might be
related to the number of times they hear those sounds. However,
it is not clear if this is due to the frequency of individual
speech sounds themselves, or the larger structures which these
make up (i.e. words). In addition to this, there may be general
patterns (or rules) in the ambient language which either
facilitate or constrain the accurate learning and production of
speech. To address these issues, this study takes place over
three years, investigating the early language development of six
children's language. This will video and audio record the
natural linguistic development of the children and the language
produced by their parents/carers whilst innatural spontaneous
interaction with one another. To assess children's production
accuracy of low probability/frequency sounds (to see if they can
produce sounds that might not be recorded in the first part of
the study), the spontaneous study
