Speak Thai, hear English — voice translation with your microphone

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

Thai carries five tones and marks politeness with the particles khrap/kha. Whisperr’s speech recognition covers the Thai spoken across Thailand.

English keeps a fixed subject-verb-object order and no grammatical gender, so it is often the structurally simpler side of a pair. Recognition likewise covers the English of North America, the United Kingdom, and far beyond.

The transcript shows each side in its own writing system: the Thai script, written without spaces between words for Thai, the Latin alphabet for English. 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, Thai to English 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??”
