“Thus, how do the children correct their misutterances?"  I mean "their wrong expression like I eated an apple.

Answer

I think 'mistakes' is most appropriate. 'Utterance' is not a common word in spoken english. 

Or 'grammar mistakes' would be the term used in school.

Answer

Synonyms: word, sound, note, noise, exclamation

Antonym: silence
