Speak Korean, hear Vietnamese — voice translation with your microphone

Tap the mic and start speaking — Whisperr listens to spoken Korean through your microphone and translates it to Vietnamese in about 0.2 seconds, read aloud or shown on screen. No typing and no text boxes: real-time voice translation built for actual conversation.

It works in both directions automatically: speak Vietnamese back and it returns Korean. One phone between two speakers is enough for a whole conversation. Try it with your own voice in the live demo above — free, no sign-up.

Whisperr review

“I love how easy Whisperr is to use and how it accurately understands and translates text and speech across different languages. It's so effective that even in scenarios where other tools might fail, Whisperr performs perfectly. Additionally, the ability to select languages for translation directly on a phone is fantastic. This feature helps us translate church services, ensuring everyone understands without missing anything important. The initial setup was straightforward, making it smooth to start using immediately.”

Top-Notch Speech Recognition and Flashcard-Style Translations for Fast Study

“Whisperr's speech recognition and translation quality are both top-notch, and better than similar tools I've tried so far. Beyond that, as a Japanese learner, I especially like how Whisperr displays each sentence and its translation almost like flashcards, with a text-to-speech button for each one. That setup makes studying feel fast and efficient, and it's easy to review sentence by sentence.”

Worth hundreds of thousands of yen

“The same performance as other conversation translation apps. Those charge by the minute, but this one is apparently a one-time purchase, so the value for money is outstanding. Compared with about five similar apps, this one is the best on both performance and price. I wonder whether it was made by a Japanese developer??”

What to expect translating Korean and Vietnamese live

Korean puts the verb last and encodes respect in its speech levels, so the same sentence changes shape with the listener. Whisperr’s speech recognition covers the Korean spoken across South Korea.

Vietnamese distinguishes six tones and attaches classifiers to most nouns. Recognition likewise covers the Vietnamese of Vietnam.

The transcript shows each side in its own writing system: Hangul for Korean, the Latin alphabet with tone diacritics for Vietnamese. Vietnamese is a tonal language, where pitch changes a word’s meaning, so translation works on whole phrases rather than isolated words. Because Whisperr auto-detects which of the two languages is being spoken, Korean to Vietnamese conversations flow in both directions without switching anything by hand.
