To form the sound correctly, the tip of the tongue is on the alveolar ridge (the hump behind the upper front incisors). The sides of the tongue touch the sides of the teeth. The air travels over the center of the tongue. It is sometimes referred to as “the snake sound: s-s-s-s.” For some children it is easier to start with a "t" sound for placement. Repeat the "t", then move to the "s" like "t-t-t-sssss". Once the child can repeat "t-t-t-sssss" accurately, try words that end with "ts". |
