Articulatory Description of Affricate Production in Speech Disordered Children Using Electropalatography (EPG)

This study used EPG to investigate some articulatory characteristics of affricates in ten children with functional articulation disorders. All the children had distorted productions of sibilant target ///. One assumption was that there would be perceptual and EPG similarities between the children's productions of /[/ and the fricative component of /tf/. The evidence from the majority of the children supported this view. Whilst the children showed considerable variability in their tongue-palate contact patterns for distorted productions, a general finding was that articulatory placement for the stop component of the affricate was closer to /?/ than to /t/. This was interpreted as suggesting that children may regard affricates as essentially fricatives with abrupt onsets. There was also a trend for increased tongue-palate contact for the stop component of /?/ compared to /?/.
