Devoicing is a phonological process that can occur in children with typical phonological development and in very early age, usually under three.

Why does Devoicing happen?

Most commonly, the change is a result of sound assimilation with an adjacent sound of opposite voicing, but it can also occur word-finally or in contact with a specific vowel.

What is an example of Devoicing?

In PHONETICS, the process by which SPEECH sounds that are normally voiced are made voiceless immediately after a voiceless obstruent: for example, the /r/ in cream /kriːm/ and the /w/ in twin /twɪn/.
