What is the difference between Aural and Oral?

These words are homophones. Both of them speaks about our senses.

When I say "Aural", it is related to your hearing ability.

Ex- Listen the audio carefully, use your aural comprehension skills to grasp the meaning.

But when I say "Oral", it is related to mouth or speaking.

Ex- In order to gain oral fluency you need to practice a lot.

Inshort, aural is about what goes in (the sound); oral is about what comes out, the speech or goes in (the food).
