Can't catch spoken English?
You've never met its linked 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 — spoken English merges words into sounds that look nothing like the spelling. 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.

Linking: real examples
Let's go straight to a real example.
Example: focus on
First, press play. This is from a MacBook review, where the speaker says he can now focus on building, replying to comments, and making better videos. Pay attention to how the two words focus on sound in the middle of the sentence.
On paper, the speaker says “focus on.”
But the sound that actually comes out is:
focus on = “fo-cu-son”/ˈfoʊ.kə.sɑːn/
What happens here is very simple.
- The /s/ at the end of focus attaches to the vowel of on (linking) — the /s/ that should close the word “focus” connects straight into the next vowel and builds a new syllable: “son.”
- The word boundary disappears — the break between focus and on no longer exists in the sound. What goes by is “fo-cu-son,” in one breath.
The vowel of “on” stays perfectly clear — only the position of the break moves. No sound is weakened, nothing is dropped. This is linking in its purest, smallest form.
Here is the same “fo-cu-son” from a different speaker. In a South African business show, an entrepreneur says she wants to get back to basics and focus on results.
Now that you know the sound shape “fo-cu-son,” play the cards again. Tap focus or on inside a card to replay from that word. Different speakers, same change — you can hear it once you know it.
Example: come across
One more, this time with two links in a row. In a thrift-store shopping vlog, the speaker says she has not come across a brown cardigan recently. Listen for the three words come across a.
On paper, she says “come across a.”
But the sound that actually comes out is:
come across a = “cuh-muh-cross-uh”/kə.mə.ˈkrɑː.sə/
Let's break it down step by step.
- The /m/ at the end of come links to the first vowel of across — instead of closing the word, the /m/ opens the next one: “muh.”
- The /s/ at the end of across links to a — the same thing happens again: “suh.”
- The word boundaries disappear — three words on paper, but one unbroken run of sound: “cuh-muh-cross-uh.”
The same consonant-to-vowel linking as in focus on, twice inside a single phrase. Come across (to find something by chance) is an everyday expression — worth knowing by its real sound, not just its spelling.
Now that you know the sound shape “cuh-muh-cross-uh,” play the card again. Tap come or across to replay from that word.
So how do you start hearing it?
You probably know the phrase come across. And still, “cuh-muh-cross-uh” 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.
