Start here

Americans pronounce "He is researching the effects of deforestation on soil erosion" as "hee ihz ruh-SUR-chuhng dhee uh-FEHKTS uhv dee-for-uh-STAY-shuhn ahn SOYL uh-ROH-zhuhn" in casual speech. Several things bend the textbook pronunciation. The headline is the Silent T in Clusters — the T inside the consonant cluster drops out. It lands on effects, and it's why Americans sound more relaxed than the textbook. Keep stressed words long, unstressed words short, and link the consonants forward into the vowels.

Common mistakes

Pronouncing the T in a consonant cluster.

In "effects", the "t" is squeezed between other consonants and drops out — the surrounding consonants flow together without it — most natural in flowing, casual speech; in careful or formal speech, the T may be lightly present. /t/ is dropped entirely — the surrounding consonants flow together without the T.

Treating every L the same.

The L in "soil" is a dark L — the back of the tongue rises toward the soft palate, adding a small "uh" quality before the L. Dark L adds a small schwa-like "uh" before the L. The back of the tongue lifts toward the soft palate.

What's happening in this sentence.

Small tricks that turn a textbook sentence into how an American actually says it.

Questions

Questions people ask about this.

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.
