How to pronounce audiobooks in American English
AH·dee·oh·buuks
Start here
Americans pronounce audiobooks as AH-dee-oh-buuks (/ˈɑdiˌoʊˌbʊks/). In "audiobooks", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. This is called the Flap T, a small move that separates 'classroom' from 'native'. So instead of AH·tee·oh·buuks, you get AH·dee·OH·BUUKS. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "He prefers audiobooks because he can listen while commuting".

Questions
Questions people ask about this.
How is "audiobooks" stressed in American English?
Stress falls on the first syllable — say "AH" with a longer, fuller vowel and keep every other syllable short and quick. The respell "AH-dee-oh-buuks" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why doesn't the T sound like a T in "audiobooks"?
In American English, when /t/ sits between two vowels with the second one unstressed, it turns into a quick D-like flap. So "audiobooks" sounds closer to "AH-dee-oh-buuks" than to a crisp-T pronunciation. This is the flap-T rule, one of the most distinctive sounds of casual American speech.
Is the American pronunciation of "audiobooks" different from British English?
American English uses different vowel shapes, a relaxed retroflex R, and connected-speech tricks like flap-T and glottal-stop T that British Received Pronunciation generally avoids. The respell "AH-dee-oh-buuks" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
