What is Strong Sound Preference?
Strong Sound Preference is a phonological process not consistent with typical development and indicative of a phonological disorder if present in more than 10% of the child’s speech. In Strong Sound Preference, one sound is overused in place of many other sounds or clusters. This process overrides other processes that may be present in the child’s words.
In this process, the overused sound may be any sound that the child overuses, and may be in any position of the word.
Example: overuse of /f/
kitty cat = fiddy fat
pretty dog = fiddy fof
big plate = fig fate
great time = fafe fime
not mine = fot fine
