Understand them.
Then know what to say.

Translation apps help you follow what is said, then leave you on your own. EchoBridge helps with both halves: you hear them in your language, in your own headphones, as they speak. Then three replies appear in theirs. Tap one and your iPhone says it.

A café in Medellín. Grey italic is still being heard.

Understanding is only half a conversation.

The other half is answering, and that is where most translators stop. EchoBridge is built for both.

Understand

Hear It as It's Said

EchoBridge doesn't wait for the end of a sentence. It translates in short phrases as they settle and speaks each one into your headphones: AirPods, Bose, or any other Bluetooth pair. The original and the translation stay on screen, so you can read along when it's noisy.

Respond

Know What to Say Back

When they finish, three short replies appear in their language, each with its meaning in yours: one to say yes, one to ask something, one to decline politely. Tap one and your iPhone speaks it from its own speaker, so they hear it and your earbuds stay in.

Three Ways to Answer

A suggestion is a starting point, not a script. Nothing is said until you choose it.

They Said

Buenas, ¿ya saben qué van a pedir? El especial de hoy es ajiaco.

Hi, do you know what you'd like to order? Today's special is ajiaco.

Say Yes
Sí, un ajiaco, por favor.Yes, an ajiaco, please.
Ask
¿Qué trae el ajiaco?What comes in the ajiaco?
Not Yet
Todavía no, un momentico.Not yet, just a moment.

Replies are written for the conversation so far, in polite, everyday spoken language, and kept to twelve words or fewer so they are easy to say or to tap.

💬

Tap a Suggestion

Three replies, each a different intent, with the meaning in your language underneath. They follow the last few exchanges, not just the last sentence. Tap one and your iPhone says it.

✏️

Edit Before Speaking

Touch and hold a suggestion to change a word first: a dish, a time, a name. The meaning stays beside it, so you know what you're about to say.

🎙️

Hold to Talk

Rather say it yourself? Hold the button and speak in your language. Let go, and EchoBridge translates it and says it out loud in theirs.

⌨️

Type a Reply

For the quiet moments. Type in your language, preview the translation, adjust it if you like, then tap Speak.

🔈

Spoken Where They Can Hear It

Your replies come from the iPhone's own speaker, toward the person you're talking to. Your earbuds stay connected, and EchoBridge goes back to listening as soon as it's done.

✋

Never Without You

EchoBridge never speaks a suggestion on its own. If you'd rather just listen, turn suggestions off in Settings and nothing appears.

How It Works

Four steps, and the first one you do once.

1

Choose Languages

Pick the language they speak and the one you speak. Spanish and English to start; the Languages screen lists every pair your iPhone can handle on device.

2

Tap Start

Headphones in, or not. iOS shows its microphone indicator whenever EchoBridge is listening, and Stop ends it.

3

Hear Them

Short phrases arrive in your language as they're spoken, in your ears and on screen, with the original underneath.

4

Answer

Tap a suggested reply, hold to talk, or type. Your iPhone says it in their language, then goes back to listening.

Two Ways to Use It

Switch at the top of the screen, any time.

Two-way

For a Conversation You're In

Ordering, asking the way, checking in, chatting with a neighbour. Translations in your ears, suggested replies, Hold to Talk and typed replies. Swap the languages with one tap when the roles change.

Listen only

For Following Along

A tour, a meeting, an announcement, the family at the next table. No suggestions and nothing spoken back. Choose Text only to read silently, or In earbuds to hear it. A thin line marks a pause that may be a new speaker.

Ready for iPhone Duo

Built on the iOS 27.1 SDK, so it fills the Duo's displays edge to edge and lays itself out for however the phone is held: closed, open, set down like a laptop or stood up like a tent. Every orientation.

Closed

A Phone, Edge to Edge

On the outer display EchoBridge is the phone layout: transcript above, suggested replies and the Start and Hold to Talk buttons at your thumb, with History, Settings and Type a reply in a bar along the edge.

Open

Transcript Beside Replies

Open it flat and the conversation gets a side of its own: what they said on one half, your replies, Start and Hold to Talk on the other, with nothing sitting on the fold.

Laptop & Tent

Half Open on the Table

Set it half open like a laptop and the transcript takes the upright half while your replies and buttons rest on the flat half nearest you. Stand it up like a tent and the conversation faces you on one half while it keeps listening.

Everything Happens on Your iPhone

EchoBridge uses Apple's on-device speech recognition, translation and language model. There is no EchoBridge server to send anything to.

What You Need

An iPhone, and ideally a pair of headphones you already own.

ItemRequirement
iPhoneiOS 26 or later. Ready for iPhone Duo, closed or open
HeadphonesOptional. Any Bluetooth headphones: AirPods, Bose, Sony and the rest. Without them, read along on screen
Suggested repliesAn iPhone with Apple Intelligence turned on (iPhone 15 Pro or later), in a language Apple's model supports. Without it, everything else works and suggestions are simply absent
LanguagesAny pair your iPhone supports on device for both speech and translation. Spanish ⇄ English is the default and the pair it's tuned for
InternetOnce — to download a language's speech model and translation pack. After that, no

For a more natural voice, download an Enhanced or Premium voice in iOS Settings › Accessibility › Spoken Content › Voices, then pick it in EchoBridge's Settings › Voices.

What EchoBridge Is Not

It is not a simultaneous interpreter. It translates phrase by phrase, so you hear each phrase a moment after it's said. When someone talks faster than the voice can keep up, older audio is skipped and the text stays on screen.

Use it to get through a conversation, not to sign something. For medical, legal or emergency situations, find a human interpreter.

It can't separate two people talking at once, and its suggestions are only as good as what it heard. It runs on iPhone, including iPhone Duo, only for now: there is no iPad, Mac or Apple Watch app in this version.
