Start here

Americans pronounce "He studies biology and chemistry in college" as "hee STUH-deez bahy-AH-luh-jee and CHEH-muh-stree ihn KAH-luhj" in casual speech. Several things bend the textbook pronunciation. The headline is the Flap T — the T between vowels turns into a quick D-like flap. It lands on studies, the kind of sound shift that makes everyday speech feel effortless. Keep stressed words long, unstressed words short, and link the consonants forward into the vowels.

Common mistakes

Saying a hard "T" in the middle.

In "studies", the "d" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. /t/ or /d/ becomes a quick tap [ɾ] — sounds like a soft D. The tongue briefly taps the ridge behind the upper teeth.

Pronouncing the vowel before M/N too pure.

In "and", the "a" vowel before M or N raises and fronts toward [eə] — the tongue pulls up and forward, breaking the vowel into a tense glide as it anticipates the nasal. The "/æ/" vowel raises and fronts before M or N — tongue pulls up and forward, producing a tense [eə] glide (between /e/ and /ə/). Not a pure /æ/.

Questions

Questions people ask about this.

Why do the T sounds turn into D-like sounds in this sentence?

That's the flap-T rule: when /t/ sits between two vowels — inside a single word, or across the boundary between two words — Americans replace the crisp T with a quick D-like flap. It's one of the most distinctive sounds of casual American speech and one of the first things to copy if you want to sound less textbook.

Why is "he" said so quickly in this sentence?

Function words — articles, prepositions, auxiliaries, pronouns — reduce to short, unstressed schwa shapes in casual American speech. Pronouncing them fully like the dictionary entry is a dead giveaway of a textbook accent. Native speakers stress only the content words and let everything else collapse.

How are the words connected in casual American speech?

Americans don't pause between words. A consonant at the end of one word links forward into the vowel that starts the next; two vowels in a row get bridged by a tiny W or Y glide; an identical consonant repeated across a word boundary is held just once. The result is a continuous flow rather than a textbook word-by-word delivery.

Is this how the sentence is taught in textbooks?

Textbooks usually teach the citation form — every word pronounced fully, every consonant crisp, every vowel pure. Americans actually flap their Ts, drop function-word H's, link consonants forward into vowels, and reduce unstressed syllables to schwa. The respell on this page shows the casual form you'll hear in real conversations rather than the textbook version.
