Yaccel: AI Interpreter

Cross the language barrier, together.

Yaccel is an AI voice interpreter for conversations between Japanese and English, plus Vietnamese, Thai, Korean, and Chinese. It is made for the moments when you need to understand and be understood: a meeting, a landlord visit, a family conversation, a talk, or a trip.

■ Hear the speaker—even from your seat

At a presentation or meeting, use your phone's built-in microphone to pick up a speaker at a distance and see the interpretation as they speak. Follow a talk from the audience, without needing to sit near the stage.

■ Follow the conversation, not just the words

Meaning changes with the situation. Yaccel considers the flow of the conversation, so a Japanese response can be understood as the polite refusal, agreement, or nuance it is meant to convey—not merely translated word by word.

■ Ask what you missed

Did a discussion move too quickly? Ask Yaccel in chat for a summary of what was just said or for the meaning behind a phrase. Catch up after a meeting or clarify a moment in a talk.

■ Speak face to face

Tap either language button for two-way conversation interpreting. Turn the screen toward the other person to show large, easy-to-read text, then have the translation read aloud.

■ Write with more confidence

Paste a chat screenshot to understand a message and get reply suggestions that fit the conversation. Use the Yaccel translation keyboard on iPhone to translate as you type in any chat.

■ Made for life in and with Japan

For English speakers living, working, traveling, or building relationships in Japan—and for anyone who works with Japanese-speaking colleagues, managers, customers, friends, or family—Yaccel helps conversations keep moving.

Languages: Japanese, English, Vietnamese, Thai, Korean, and Chinese.
