Speak Japanese, hear Thai — voice translation with your microphone

Tap the mic and start speaking — Whisperr listens to spoken Japanese through your microphone and translates it to Thai 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 Thai back and it returns Japanese. 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.

What to expect translating Japanese and Thai live

Japanese drops subjects routinely and bakes politeness into verb endings (keigo), so context drives the translation. Whisperr’s speech recognition covers the Japanese spoken across Japan.

Thai carries five tones and marks politeness with the particles khrap/kha. Recognition likewise covers the Thai of Thailand.

The transcript shows each side in its own writing system: kanji together with hiragana and katakana for Japanese, the Thai script, written without spaces between words for Thai. Thai 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, Japanese to Thai conversations flow in both directions without switching anything by hand.

What users say

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. 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. Whisperr has removed a huge barrier to interacting with foreign-language speakers in real time, and to consuming video content that doesn't already have a translation.”

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??”
