1. Substitution: Replacing one sound with another (e.g., "wabbit" for "rabbit"). 2. Omission: Leaving out sounds (e.g., "nana" for "banana"). 3. Distortion: Altering sounds (e.g., slushy "s" sounds). 4. Addition: Adding extra sounds (e.g., "buhlack" for "black").
Each of these can affect a child's clarity of speech and should be addressed if persistent.
