Japanese speech to text — 話すだけで文字に
Dictate in Japanese or upload Japanese audio — voice messages, 会議, lectures — and get clean text in the Chrome side panel.
Japanese transcription is really a writing problem: the same sound can be half a dozen kanji, and the transcript has to pick the right one from context. Whisper AI does this well — 会議 not 懐疑 when you're talking about meetings — and it switches naturally between kanji, hiragana, and katakana, rendering loanwords like ミーティング in katakana as expected. Keigo and casual speech both come out in their own register.
Two ways to use it
Record Japanese speech, or upload Japanese audio
Record your voice
Hit the mic and speak naturally — polite or casual. The transcript picks appropriate kanji and kana for you to copy anywhere.
Upload an audio file
LINE voice messages, recorded 会議, lectures — upload MP3, WAV, M4A, MP4, FLAC, or OGG.
How it works
Three steps, no setup
Open the side panel
Click the extension icon on any website. No language settings needed — Japanese is detected automatically.
Speak or upload
Record live or drop in a file. Audio is processed securely and deleted immediately after transcription.
Copy your Japanese text
Edit the transcript in the panel, then copy it into WhatsApp, Gmail, Docs — or download it as a file.
Japanese transcription questions
Does it choose the right kanji?
Context decides — homophones like 記者 / 汽車 / 帰社 resolve from the surrounding sentence, which is what makes Whisper-class models so much better at Japanese than older dictation tools. You can fix any miss in the panel.
Can I transcribe LINE voice messages?
Yes — save the voice message as a file (LINE exports .m4a) and upload it in the panel. WhatsApp notes (.ogg) work the same way.
Does it handle keigo and casual speech?
Yes — です・ます and casual だ speech each transcribe in their own register, particles included.
What about Japanese mixed with English?
English words spoken as English stay in English; loanwords pronounced Japanese-style come out in katakana — ミーティング for 'meeting' said the Japanese way.
