A voice translator for the person standing in front of you
The receptionist in Osaka, the pharmacist in Porto, the driver in Istanbul: they are right there and you share no language. Put your phone on the counter between you. You take turns, and Déblo Duo says each sentence out loud in the other language.
Why passing the phone back and forth fails
Most translator apps make you speak, then turn the screen so the other person can read, then hand the phone over. For a quick direction it is fine. To explain a problem or agree on a price, the back and forth wears everyone out.
How it works
-
Choose “One phone”
Pick your language and theirs. The screen splits in two: the top half is turned upside down for the person facing you, with their instructions in their language.
-
Hold your half to speak
Whoever holds their half has the floor. Only one person talks at a time, so the phone never mixes two voices.
-
Listen
The translation plays on the speaker. The other person answers the same way. If they would rather use their own phone, choose “Two phones”: they scan a QR code and join from their browser.
For example
At a pharmacy counter in Porto, a traveller from Seoul explains in Korean that she needs something for a child’s fever. The pharmacist hears Portuguese, asks the child’s age in Portuguese, and she hears the question in Korean.
Questions
Do we need two phones?
No. One phone is enough, you take turns on the same screen. Two phones is an option when the other person prefers to hold their own.
Why hold the screen while speaking?
So that only one voice is translated at a time. Without it, the microphone would pick up both of you and mix the sentences.
Can it replace an interpreter at the doctor’s?
No. It helps you explain and understand, but for a diagnosis, a treatment or any decision where one word matters, ask for a certified interpreter.

Other situations
Déblo Duo is an AI interpreter and does not replace a certified interpreter. For medical decisions, legal acts or any situation where a single word matters, rely on a certified human interpreter.
