All but one of the place errors on velar targets involved fronting to an alveolar place of articulation.
This child was treated on the coronal \s\ in the low frequency condition, and the velar \d\ in the high density condition.
The interaction between vowel epenthesis and velar deletion is opaque, of the type that would be characterised as counterbleeding in theories with rule ordering.
It seems clear that the kit items that occupy the front part of the overall distribution are those that are followed by a velar consonant.
The uvular fricatives are realised as postvelar or velar fricatives, and the uvular /q/ is pronounced as a glottal stop.
Consonants are grouped into three major categories for ease of comparison with infants' vocalizations : labials, alveolars and velars.
There may also be phonetic justification for distinguishing between velar stops and fricatives.
However, even if the velar fricatives were phonemic, this would pose no problem.
