Sound for All
Captions that know which sounds your ears drop
Most hearing loss doesn’t turn the volume down. It erases specific frequencies — and with them, the quiet high consonants that tell one word from another. SoundSense learns your hearing profile, then flags only the words you’re likely to confuse.
Why volume doesn’t fix it
Vowels are loud and low-pitched. They survive almost any hearing loss, which is why speech still sounds like speech. Consonants are the opposite — the s, f, th and t that separate words live at the top of the range and carry the least energy.
So the sentence arrives with its rhythm intact and its meaning gone. Turning it up amplifies the parts you already heard. Knowing exactly which sounds are missing is the only thing that tells you which words are at risk — and that answer is different for every pair of ears.
The same sentence, two approaches
Standard captions
So the appointment moved to fifteen past four, and I can't get there before then — take the second left after the pharmacy and I'll meet you outside.
Everything, every time. You read instead of listening, and the words that actually mattered are buried in the ones that didn’t.

Two words. The rest of that sentence was never at risk for this listener, so it never appeared.
How it works
- 01
Test your hearing
Six tones, sixty seconds, in your browser. Or type in the audiogram you already have.
- 02
We map your blind spots
Your thresholds become a list of speech sounds you're losing, and from that, every pair of common words those sounds fail to keep apart.
- 03
Only see what you'd miss
Live speech is checked against your list, then against an LLM — would mishearing this actually change the meaning? Nearly always the answer is no, and the screen stays empty.
Accessibility isn’t something you install on a disabled person.
Half of every conversation happens in someone else’s mouth. So SoundSense runs the same engine in two directions: the deaf user sees the words their ears will get wrong, and the hearing person sees exactly how to say those words differently. Not “speak up” — don’t contract the negative, read the digits separately, face them while you talk.
