What does onomatophia mean?

There seems to be a slight error in the term you're looking for. "Onomatophia" is not a recognized word in English.

It's likely you're referring to onomatopoeia, which is a figure of speech that uses words whose sound imitates the sound they describe.

For example:

* Buzz for the sound of a bee

* Meow for the sound of a cat

* Bang for the sound of a door slamming
