Knowing how to pronounce "audio" correctly is an important part of speaking English fluently. Here are a few tips to help you get the pronunciation just right.

First, make sure to stress the first syllable of the word. Say the word with the emphasis on the "Au" sound.

The first syllable should be pronounced like "Ow" as in "Ow, that hurts!" The second syllable should sound like "dee-oh".

The "Au" is pronounced with a short "uh" sound, and the "dee" should be pronounced with a long "ee" sound.

When you put the syllables together, it should sound like "ow-dee-oh". The emphasis should be on the first syllable, so it should sound like "ow-DEE-oh".

Practice saying the word out loud a few times to make sure you're pronouncing it correctly. With a little bit of practice, you'll soon have the correct pronunciation of "audio" down pat.
