Pronouncing the silent T after N.

In "into", the "t" right after N is dropped — the tongue skips the T stop and moves directly from the N position to the next sound. /t/ is completely silent — the tongue skips the T stop and moves directly from the N position to the next sound.

Treating every L the same.

The L in "cells" 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.

Reduced Words (to, for, of) in "have""have" is a function word — in connected speech, the full vowel reduces to a quick "hav" sound and consonants may simplify.

h→∅

Silent H (in him, her, has) in "have"The "h" in "have" is dropped in connected speech — the preceding word's final consonant links directly to the remaining vowel — most natural in casual, rapid speech; in careful or formal speech, the H is typically kept.

ə→◌

t→∅

Silent T after N in "into"In "into", the "t" right after N is dropped — the tongue skips the T stop and moves directly from the N position to the next sound.

Silent T/D Across Words between "different" & "cell"The "t" at the end of "different" is dropped before the consonant starting "cell" — the surrounding consonants flow directly together — common in flowing natural speech; in careful or formal speech, the sound is often kept.

Questions

Questions people ask about this.

Why is "have" 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.

Why does the H in "have" sound dropped here?

In casual speech, Americans drop the H from unstressed function words like "he", "her", "him", and "his" when they sit inside a sentence. So "tell him" sounds like "tell-im". The H stays only when the word is sentence-initial or carries emphasis.

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.
