All Voices

Live translation · On campus

Live translation for lectures and classes

Stay with every class.

Updated 10 October 2026.

To follow a lecture in a language you are still learning, put your phone where it hears the lecturer and start All Voices. Every sentence appears in your language as it is spoken, with the original underneath, and the lecture is saved as a meeting for revision. A lecturer can also open the session so that the whole class follows on their own phones.

In the lecture

Place the phone where it hears the lecturer, on the desk or near the front. The translated transcript keeps going without stopping the class for you. Because the original stays under each translated line, you also see how the lecturer said it, which helps when you are learning the language of the course.

Course vocabulary is where general translation goes wrong. Paste the glossary from the course page, or upload the lecture notes, and All Voices suggests terms to recognise: names, formulas spoken as words, technical terms. You accept the ones you want, and they apply in every session.

Live captions also help in your own language, when the room is noisy or an accent is hard to follow.

Seminars, office hours and group work

Revising

For lecturers

International students can follow your lecture on their own phones. Run All Voices on your laptop or phone, open the session to an audience, and show the QR code on a slide. Students choose their language and read captions or listen with earphones. They need no app and no account, and they pay nothing; their time comes out of your hours.

On the free trial, up to three listeners can join, enough to try it in office hours. Details on audience listening.

What it costs

Students pay for their own sessions: one hour of lecture uses one hour of prepaid time. The small pack is $9 for 6 hours; $19 buys 30 hours, about twenty 90-minute lectures. Hours never expire, so unused time carries over to the next semester. The first 30 minutes are free, without a card. See pricing.

Study support, not an official accommodation

Follow your campus recording rules and ask the lecturer first. Verify material that affects an exam, a safety instruction or a formal submission. Students who need an official accommodation, such as live captioning or sign language interpreting, should ask their university’s disability or accessibility service. Live text needs an internet connection; if it drops, All Voices keeps the recording while it reconnects.

Questions people ask

How can I translate a lecture live on my phone?

Start an All Voices session where your phone hears the lecturer. Every sentence appears in your language with the original underneath, and the lecture is saved as a meeting for revision.

Can a lecturer give the whole class translation on their phones?

Yes. The lecturer opens the session to an audience and shows a QR code. Students choose their language and read or listen, with no app and no account.

Can I revise from it afterwards?

Yes. Search the transcript, replay any line, read the summary in your language, or ask the saved lecture a question.

Am I allowed to record a lecture?

That depends on your campus rules. Ask the lecturer first. All Voices saves the audio of every session, so the same rules apply as to any recording.

What does it cost for a student?

One hour of lecture uses one hour of prepaid time. $19 buys 30 hours, and hours never expire. The first 30 minutes are free.
