Which phonological process is known to disappear by the age of 3?

Final consonant deletion is a phonological process where children omit the final consonant of a word, which is often observed in young children's speech as they are still mastering the complex sounds of their language. This process typically disappears by around age 3, as children's phonetic abilities develop and they become more proficient in producing the full range of sounds in their language.

The disappearance of final consonant deletion marks a significant developmental milestone, indicating that the child is beginning to achieve better phonological awareness and speech sound production. It is important for parents and educators to monitor these phonological processes, as continued use may indicate the need for additional support or intervention to promote speech development.

The other phonological processes mentioned, like devoicing, stopping, and fronting, may persist beyond the age of 3, as children continue to adjust and refine their speech production skills over a longer period. Each of these processes follows a different developmental trajectory, reflecting the complexities of language acquisition.
