Translate spoken French to English on a call or in a voice message
Most translators make you type. If you're looking for a way to translate French to English by voice, you probably want to hear the other person, not read a text box. Trilyo is a chat app built for that. You and the other person each use Trilyo on your own phone, pick your language once, and then just talk. When they speak French, you hear English. When you answer in English, they hear French.
French to English voice translation during a call
Start a call the way you would in any messaging app. As the other person speaks French, Trilyo translates their speech and you hear it in English as the call goes on. Your replies go the other way, so they hear you in French. There's no interpreter on the line and nothing to copy and paste — just two people talking, each in their own language.
That makes it easier to call family in France, a landlord in Montréal, a supplier in Lyon or a colleague in Brussels. For a walkthrough of how translated calls work, see our guide on how to talk to someone who speaks a different language on a phone call.
A practical tip: translation quality depends on clear audio and the language pair. A quiet room, a steady connection and one person speaking at a time all help.
Translate French voice messages to English
Not every conversation needs a call. When someone sends you a voice message in French, it reaches you in English, and you listen to it like any other voice note. Record your reply in English and they hear it in French. Voice messages are a relaxed way to handle spoken French when you're in different time zones or can't take a call right now. More on this in how to send a voice message to someone who speaks a different language.
Translate chats from French
Text works the same way. Every French message you receive shows up in English, and what you type in English arrives in French. You stay in one conversation instead of switching between a chat app and a separate translator.
How do I translate an email from French to English?
Trilyo isn't an email tool, and it doesn't translate your inbox. But if a French email is the start of an ongoing conversation — with a host, a client or a relative — you can invite that person to Trilyo and carry on in chat, where every message is translated in both directions. If it's easier to talk it through, you can switch to a call or a voice message in the same conversation.

Frequently asked questions
Can Trilyo translate spoken French to English during a phone call?
Yes. On a Trilyo call between two phones, each person speaks their own language. When the other person speaks French, you hear English during the call, and what you say in English reaches them in French. Translation quality depends on clear audio and the language pair.
Can I translate a French voice message to English?
Yes. A voice message recorded in French reaches you in English, and a voice message you record in English arrives in French. You listen to it like any other voice note.
Can Trilyo translate an email from French to English?
No. Trilyo translates chat, voice messages and calls, not email. If you're in an ongoing email exchange, you can invite the other person to Trilyo and continue the conversation in chat, where every message is translated in both directions.
Do both people need Trilyo?
Yes. Trilyo works between two phones. Each person uses Trilyo on their own phone and picks their language once, and after that every message, voice message and call is translated for both sides.
