The Effects of Phonological Complexity on Word Production in French-Speaking Children.
Margaret Kehoe
PMID 38563416WHAT IT FOUND
For French-speaking children aged 2 to 3, complex words are harder to produce, matching English-based indices.
For ages 3 to 4, those indices lose sensitivity because most sounds are mastered, except alveopalatal fricatives, which remain difficult.
Key findings
01Phonological complexity strongly correlates with lower production accuracy in children aged 2 to 3, but this relationship weakens or disappears in children aged 3 to 4.
02Alveopalatal fricatives (sounds like /ʃ/ and /ʒ/) are the only complexity parameter that significantly predicts poor accuracy across all age groups.
03English-based complexity measures (IPC and WCM) are less sensitive for older French-speaking children than a simpler four-parameter index focusing on fricatives/liquids, codas, clusters, and alveopalatal fricatives.

What it does not show
The study used cross-sectional data, so it cannot track individual developmental trajectories. High accuracy scores in older children created ceiling effects, potentially masking complexity influences. Multisyllabic words were not sampled in the youngest children, limiting conclusions about word length effects at that age. The databases were not originally designed to test complexity, so word selection may not have covered the full range of complexity evenly.

The easy way to misread this
Do not assume that high phonological complexity always predicts poor production accuracy in French-speaking children over age 3. The study found that standard complexity indices lost sensitivity in this age group because most French children have already mastered the features those indices weigh heavily.
