Translate spoken Korean to English on calls, video calls and voice messages
If you need to translate Korean to English by voice, a dictionary or text box is not enough for a back-and-forth conversation. Trilyo is a chat app built for that exchange. You and the other person each use Trilyo on your own phone, choose your language once, and then speak or type. When they speak Korean, you hear English. When you answer in English, they hear Korean.
Korean to English voice translation on a call
Start a call in Trilyo when you need to speak with someone who uses Korean. You speak Korean, finish your turn and pause, and the other person hears English. When they answer in English, you hear Korean. Each person stays on their own phone, and the conversation works in both directions without an interpreter or a copy-and-paste step.
That can help when you are calling family in South Korea, speaking with a host, coordinating with a supplier or handling a customer conversation. Clear audio and taking turns help the translation work as expected. For a practical walkthrough, read how to talk to someone who speaks a different language on a phone call.
Korean and English video calls with subtitles
When seeing the other person matters, Trilyo also supports video calls with translated subtitles. You can speak Korean while the other person follows the English subtitles, then they answer in English while you follow Korean. Take one turn at a time so each phrase can be processed and shown clearly. The feature keeps the conversation on two phones rather than asking both people to share one screen or switch between apps. See how to video call someone who speaks a different language for a related guide.
Translate Korean voice messages to English
Not every conversation needs a call. A voice message recorded in Korean reaches you in English, and a message you record in English reaches the other person in Korean. Voice messages are useful across time zones or when one person cannot talk at that moment. For tips on this format, see how to send a voice message to someone who speaks a different language.
Translate Korean to English text messages
Chat works in both directions too. A Korean message shows up in English for you, and what you type in English arrives in Korean. The translation happens inside the Trilyo conversation, so invite the other person there instead of moving between a chat app and a separate translator.
