Captionsthat speak
More than reading captions — the moment the speaker talks, everyone's phone updates in sync, and you can have the translation read aloud, like an interpreter right beside you.

CAPTIONS WITH A VOICE
Translation you can see — and hear
Captions aren't the end. Finalized translations can be read aloud in a natural voice — like an interpreter beside you — so you don't have to keep staring at a screen.
- Simultaneous: reads each translation the moment it's finalized, keeping pace with the speaker
- Consecutive: reads a whole segment after the speaker pauses, muting the mic to avoid feedback
- Reads only finalized text, never the live captions still being revised
- Read-aloud shares the same 60-language list as captions and translation
USE CASE 1 · PERSONAL
Business trips or cross-border calls — two-way conversation from one phone
Talking face-to-face or on a call, each side sees (and can hear) the translation in their own language — no middleman, no extra gear.
- Two-way live translation: you speak Chinese, they hear English; they speak English, you hear Chinese
- No install — just a browser, no app to download
- Switch Traditional/Simplified Chinese instantly to match the reader
- When looking down isn't convenient, switch to listening instead
USE CASE 2 · TALKS & EVENTS
A 150-person talk — captions delivered to every phone in sync
The speaker opens a room and talks into the mic as usual; everyone in the audience opens their phone, enters the room code, and sees (and can hear) live translated captions — no headset receivers to set up, no app to install.
- Repeatedly load-tested in production for up to 150 viewers in one room
- Browser-side encryption with ciphertext fan-out — the speaker's phone no longer maintains one long-lived connection per viewer
- Simultaneous read-aloud, or consecutive to read a whole segment after each pause
- Viewers only need the room code — no account required
USE CASE 3 · ONLINE MEETINGS & VIDEO
Teams, Google Meet, Zoom — plus any online video or livestream
Oralion doesn't only take the live mic — it can capture the audio of a browser tab or window on this computer. Can't follow a cross-border video call? Share the meeting tab's audio with Oralion to read along in real time, or listen to the translation on headphones — same for foreign-language videos, YouTube livestreams, and online courses.
- Works with web-based Teams / Google Meet / Zoom — just share the meeting tab's audio
- Watch YouTube, online courses, or foreign-language streams with captions and translation keeping up live
- Set the audio source to "tab/window audio" — no cables to plug in
- Keep it to yourself (headphones + simultaneous interpretation), or open a room to share with others
USE CASE 4 · RECORDINGS YOU ALREADY HAVE
Not everything happens live — upload a recording, get a transcript
Interviews, meetings, recorded lessons, field recordings — hand Oralion a file you already have and it comes back as a transcript, with recognition slips and punctuation cleaned up and paragraphs sorted out by AI. Nothing to sit and watch; come back when it's done.
- MP3, M4A, WAV, MP4 and more — audio or video, up to 200 MB / 8 hours
- Optional speaker separation — interviews and meetings come back labelled
- Two editing styles: keep the speaker's own wording, or strip fillers and repetition for a cleaner written transcript
- Included in every subscription under fair use, at no extra charge. On Free or credit packs it's 0.5 Credits per hour of audio — half the price of live interpretation.

HOW IT WORKS
Three steps — nothing to learn for speakers or viewers
01 OPEN
Pick languages, go live
The speaker logs in, picks the spoken and target languages, and hits broadcast to start capturing audio.
02 SHARE
Give viewers the room code
Read out the room code, or drop the link in a chat — viewers don't need to create an account.
03 CAPTIONS
Viewers see — and hear — the translation
Captions arrive in real time, and read-aloud can play them simultaneously or consecutively when you want it.
