Can't catch spoken English?
You've never met its changed sounds.
You know the words. You can read the sentence. And yet, in real conversation, it slips right past you. In most cases the problem isn't vocabulary — in real speech, sounds change into different sounds under the influence of the sounds next to them. This guide lets you hear it happen in real YouTube clips: play each example, slow it down, and replay it as many times as you need.

Assimilation: real examples
Let's go straight to a real example.
Example: get it
First, press play. This is from a cosmetics review, where the speaker says you can get it for $14 until July 11th. Pay attention to how the two words get it sound in the middle of the sentence.
On paper, the speaker says “get it.”
But the sound that actually comes out is:
get it = “ge-dit”/ˈɡɛ.ɾɪt/
What happens here is very simple.
- The /t/ at the end of get is caught between vowels — there is a vowel before it (the e of get) and a vowel right after it (the beginning of it). Across the word boundary, the /t/ ends up sandwiched.
- The sandwiched /t/ changes into a d-like tap (assimilation) — in American English, a /t/ between vowels turns into a quick, light tap that sounds close to a d: “ge-dit,” not “get it.”
The letter t is right there in the spelling, but no “t” sound comes out — nothing else is mixed in, so this is assimilation in its purest, smallest form. The same change is everywhere: it's why water sounds like “wah-der” and better like “beh-der.”
Now that you know the sound shape “ge-dit,” play the card again. Tap get or it inside the card to replay from that word.
Example: put it on
One more, this time with the same change happening twice. In a TV review, the speaker explains that with the center mount you can put it on a smaller TV stand. Listen for the three words put it on.
On paper, he says “put it on.”
But the sound that actually comes out is:
put it on = “pu-di-don”/ˈpʊ.ɾɪ.ɾɑːn/
Let's break it down step by step.
- The /t/ of put is caught between vowels and changes (assimilation) — a vowel before it (the u of put), a vowel after it (the beginning of it): “pu-di,” not “put.”
- The /t/ of it changes too (assimilation) — the same thing again, this time in front of the vowel of on: it makes “don.”
- The word boundaries disappear — three words on paper, but one unbroken run of sound: “pu-di-don.”
The same “/t/ trapped between vowels” change as in get it, twice inside a single phrase. Put it on (to place something on something) is an everyday expression — worth knowing by its real sound, not just its spelling.
Now that you know the sound shape “pu-di-don,” play the card again. Tap put or it to replay from that word.
So how do you start hearing it?
You know the phrase get it — everyone does. And still, “ge-dit” slips past you in conversation. The reason is simple: you had never met that sound shape. And here is the tricky part — a sound you don't know just goes by as “something I missed.” You can't even notice what you don't know.
So the work splits into two stages.
Stage 1: Find out what you don't know.
Check the real sound shape of the part you couldn't catch, and recognize: “I never knew this sound.” The listen-then-learn flow of this guide is built to give you that first stage on the spot.
Stage 2: Repeat until it's familiar.
Unfortunately, knowing alone doesn't make you hear it. You need to listen to the real audio again and again, turning a sound you know into a sound you're used to. That's the stage where the parts you couldn't hear start coming through.
About VoiceGlyph
We build a tool for doing exactly these two stages — learn the sound shape, then replay until it's familiar — right on top of YouTube. When you hit a moment you can't catch in a video you're watching, you can turn those few seconds into a card, keep it with a translation and a listening tip, and replay it any time. The cards embedded in this article are the actual product: play from any point on the waveform, slow it down, tap a word, and check it until it clicks.
