I am working with a 4 year old boy with Sensory Processing Disorder. When producing the /s/ phoneme he takes a quick inhalation of air. He is able to produce /z/ and /sh/ with appropriate outward flow of air. We have worked on discriminating correct vs. in correct airflow, horn blowing, air hockey with cotton ball or whiffle ball, and cheerio for tongue tip placement with adding the airflow as well. Despite max attempts he is unable to produce the sound in isolation. Any tips or advice you could provide would be greatly appreciated!
I would work on voice versus voiceless sounds. Having him feel your throat to see that with the "z" you are using your voice box and call "s" your quiet sound and work on the difference that way. Another thing that I have tried to help with placement is a straw placed on the tongue down the middle out of the front of the mouth. This helps kids to feel where the air needs to go. But it sounds like he has the placement piece since he is able to say the "z". Just something extra to try. There is also a complete list of oral placement activities to work on "s" and "z" on page 18 in Sara Rosenfeld-Johnson's book: Oral Placement Therapy for Speech Clarity and Feeding. This will give you a list of other activities to try. Let us know if we can do anything else to help.
