Every conversation you have been missing

For people who are deaf or hard of hearing, everyday life is full of moments that require workarounds. Soniox App removes most of them.

storefront

Run errands independently

Pharmacies, post offices, grocery stores, government offices. Soniox App captions what the person behind the counter is saying in real-time, so you can handle your own errands without bringing someone along to interpret.

groups

Follow group conversations

Dinner tables, team meetings, social gatherings. When multiple people are talking, Soniox App separates and captions each speaker automatically so you can follow who is saying what, even when you cannot see everyone's face.

record_voice_over

Talk to strangers freely

Asking for directions, chatting with a neighbor, or speaking to a doctor you have never met. Soniox App captions speech from anyone, not just people who know how to communicate with you.

work

Participate fully at work

Meetings, hallway conversations, presentations, and calls. Soniox App captions everything in real-time so you can contribute, respond, and stay informed without relying on a colleague to relay what was said.

local_hospital

Navigate medical appointments

Doctors speak quickly and use complex language. Soniox App gives you an accurate, real-time transcript of everything said during appointments, so you can ask the right questions and leave knowing exactly what was discussed.

flight

Travel without barriers

Airports, train stations, hotel check-ins, foreign cities. Soniox App captions and translates speech in 60+ languages so you can navigate any country and understand any person, even if they speak a different language.

Designed for how real conversations happen

The world does not slow down or repeat itself. Soniox App is built to keep up with it, so you can too.

Instant captions, no delay

Soniox App captions speech as it happens, word by word, with no perceptible lag. You read what someone is saying while they are still saying it, not after they have finished.

No lip reading required

Soniox App works on sound, not sight. You do not need to face the speaker, maintain eye contact, or be close enough to read lips. It captures speech from across the room, in any direction.

Works in noisy environments

Restaurants, busy streets, crowded waiting rooms. Soniox App is built to isolate speech from background noise so captions stay accurate even when the environment is anything but quiet.

Knows who is speaking

In conversations with multiple people, Soniox App labels each speaker separately so you always know who is talking. Especially useful in meetings, classrooms, or family gatherings where voices overlap.

Understands every accent and dialect

Soniox App is trained on real-world speech from speakers across regions, not a single standardized accent. It handles fast talkers, thick accents, and casual speech patterns that trip up most captioning tools.

Translate any language instantly

When someone speaks a language you do not know, Soniox App translates in real-time across 60+ languages. No setup, no switching modes. Just point, listen, and read in your own language.

More than captions. A fuller life.

Hearing loss affects over 1.5 billion people worldwide. For most, the biggest challenge is not sound. It is access to the everyday moments everyone else takes for granted. Soniox App gives those moments back.

school

Stay engaged in class

Follow lectures, seminars, and classroom discussions in real time without relying on note-takers or post-session transcripts. Soniox App keeps you in the room, not catching up afterward.

family_restroom

Be part of family life

Holiday dinners, birthday parties, casual kitchen conversations. Soniox App brings family moments into focus, so you are part of the conversation, not watching it happen around you.

local_cafe

Enjoy social life on your own terms

Coffee with a friend, a first date, a chat with a neighbor. Soniox App captions casual conversation in real-time so social moments feel natural and easy, not exhausting or anxiety-inducing.

diversity_3

Connect with people who do not know sign language

Most people you meet will not know how to sign. Soniox App bridges that gap instantly. Anyone can speak normally and you read exactly what they said, no shared language or training required.

Private by default

Soniox never stores your recordings and never uses your audio to train models. Everything is processed securely in real-time, then gone.
