Q: My preschool client has no fricatives or affricates. Do you have advice for getting them started?
The fricatives and affricates emerge out of the pre-speech raspberries. I would start there. The raspberries are made both with and without voice and in many places of articulation–– bi-labial, lingua-labial, lingua-velar, and nasal snort.
I have my clients makes them big and sloppy at first. Then I teach them to make the soft and gentle.
When I move on to the fricated phonemes, I teach all of them at the same time so that the child gains the concept of frication (manner) first. Once frication begins to emerge and a variety of them are emerging, then I teach the individual ones by place.
