Subtitles · Conversations in two languages

A conversation in two languages,
each of you reading your own.

Choose the microphone in Listen To, pick your language in Translate To and turn on Show Both Languages, and every sentence lands in the box twice: your language on top, theirs under it, whichever of you is speaking. A visitor at your desk, a parent at a school meeting, a colleague over from the Lisbon office. You talk, they talk, and both of you read. Nothing leaves the Mac.

The app is listening to the room. The second line is Spanish, and if you do not speak Spanish it is no use to you. Then Translate To and Show Both Languages come on: English on top, Spanish under it, whoever is speaking, so you read yours and they read theirs.

Hold and drag the captions to move them, as you would in the app.

Hold to rewind, and the last few boxes stack back up.

Click the in the menu bar: the app's menu opens, and the items marked Try all work in this demo.

Three rows in the menu, and then a conversation

Since 1.8.0 the app can listen to the room as well as to the Mac, and the translation it already did for calls and videos works in both directions once it can hear both people. Nothing to set up beyond three rows in its menu, nothing to install for the other person, and nothing that leaves the machine.

Listen To: the microphone

Off until you choose it, and macOS asks for the microphone the first time you do, never at launch. It takes the place of what the Mac plays rather than mixing with it, so a conversation is only ever the conversation. The Mac's own microphone, or whichever input Sound settings has.

Translate To: one language, both ways

Pick the language to translate into. Whatever else is said arrives in it, and what is said in it goes back into the last other language heard. Any of the sixteen into any other, on the Mac, through Apple's own translator; a pair downloads once and works with Wi-Fi off after that.

Show Both Languages: one box, two paragraphs

The Translate To language on top as the caption, the other language under it in a smaller run. The same language is never shown twice, a page turns when either paragraph fills, and it is held long enough to read the slower of the two.

It hears who is speaking

The recogniser tells which of the sixteen is being spoken, sentence by sentence, so nobody presses anything between turns. Translation works in turns too: a pause closes one and the next starts clean, rather than the whole conversation being retranslated every time someone finishes a sentence.

Readable from across a table

The box floats above everything on the screen. Hold ⇧ and drag it to the edge nearest the other person, take the size up in Text Size and Alignment, and hold ⌥ to bring back the last few sentences when somebody missed one.

Nothing leaves the Mac

Recognised on the Neural Engine, translated by Apple's framework on the machine, drawn and discarded. No account, no recording, no transcript to delete afterwards, and the orange microphone indicator in the menu bar the whole time it listens.

The conversations it was built for

Two people, one Mac between them, and a language one of them does not have. The situations are ordinary; what was missing was a caption both of them could read.

  • A visitor at the desk. A reception, a hotel's front desk, a clinic's front office: turn the Mac a little towards them and both halves of the exchange are captioned, in both languages.
  • The parent-teacher meeting. Twenty minutes, one Mac on the table. The parent reads what the teacher said in their own language, and the teacher reads the answer in theirs.
  • A colleague over from another office. A week in the same room with someone whose English is as good as your Portuguese: enough to work, not enough to argue a design through. The arguing gets captioned.
  • A relative who never learned your language. The one at the end of the table who nods along. A laptop between you, turned their way, and the evening is a different evening.
  • A language exchange, in person. Each of you reads the other in your own language and hears the original at the same time. That is the exchange, with the stuck moments taken out of it.

Worth knowing before you rely on it

It is a microphone, a speech recogniser and a translator, and each of the three has an edge. Knowing where they are is most of getting a good conversation out of it.

  • It hears what the microphone hears. A laptop across a quiet table is a fair job; a busy café is the hardest audio there is. An external microphone, or the Mac nearer the person speaking, helps more than any setting.
  • One source at a time. The microphone takes the place of what the Mac plays. For a call, choose All system audio again; for the room, the microphone. Not both.
  • It is speech recognition, so it is wrong sometimes. Names, jargon and two people talking at once are where it slips. For a medical, legal or official conversation an interpreter is the accommodation; this helps, it does not stand in.
  • macOS 15 for the translation. The microphone works from macOS 14.2 and transcribes what it hears. Translate To and Show Both Languages arrive with macOS 15, where Apple's Translation framework lives.
  • Sixteen languages. The other person's has to be one of them: English, Spanish, French, Italian, Portuguese, German, Dutch, Turkish, Russian, Ukrainian, Arabic, Hindi, Japanese, Korean, Vietnamese and Chinese.

Conversation questions

Do we both need to look at one screen?
Yes: one Mac, one caption box, two paragraphs. Turn the Mac a little, or hold ⇧ and drag the box to the edge nearest the other person, and take the size up from Text Size and Alignment. On a call the app captions the other side; in the room, both of you.
Do I have to tell it which language each of us speaks?
No. The recogniser works out which of the sixteen is being spoken, sentence by sentence. You choose the one language to translate into; anything else that is said arrives in it, and what is said in it goes back into the last other language it heard. Until it has heard a second language there is nothing to translate back into, and a sentence in the target language stays as it was said.
Does it record us?
No. Nothing is written to disk and nothing leaves the Mac; the ⌥ stack keeps the last few boxes in memory until you quit. macOS shows its orange microphone indicator in the menu bar the whole time the app is listening, as it does for any app.
What does the other person need?
Nothing. No app, no account, no phone on the table. They read the box on your screen, in their language, and hear you in yours.
Can it do the room and a call at the same time?
No. Listen To is one source: the microphone or what the Mac plays. Choosing the microphone again puts it away, and capture goes back to the source it replaced.
How good is the translation?
Apple's own, the one in the Translate app, running on the Mac. Good enough to follow and to answer, not a certified translation, and a sentence that arrives oddly is worth asking about. Names are where it slips most, in both languages.

You talk. Both of you read.
