Denasalization is the phonological process where a child replaces a nasal consonants like the “m” and “n” sounds with  non-nasal consonant like “b” and “d”.

Nasal consonants are where air is released thru the nostrils.  “m” and “n” examples of nasal consonants.

A tip to help the child see airflow coming out of their nostrils is to place a mirror under your / their nose during the production of nasal consonants.  The mirror should fog up from the nasal emissions.  If no mirror is present, have the child place a finger under your / their nose to feel the air stream works too!

Examples of denasalization include:

• “do” for “no”
• “de” for “me”
• “ot” for “on”

It is common for all children to make theses errors; however, if the errors persist after the child turns three, you may want to consult a school / local Speech-Language Pathologist to see if they qualify for services.
