Air then passes over the sharp edges of teeth. When I say [s], the tip of my tongue braces against the lower gums, and the blade of the tongue presses toward the alveolar ridge, leaving a gap, producing [s]. I have a speech impediment that manifests itself from time to time. Every so often when I pronounce [s], it comes out as a high pitched whistle. It's rather cool. I remember going to the speech therapist because as a kid, but I'm not sure for exactly what (I'd have to ask my parents).
