Japanese to English voice translator
Speak Japanese and hear English — or speak English and hear Japanese — in under a second. Speaklu is a live Japanese to English voice translator that also shows a text transcript and translates Japanese audio from videos as it plays.
Translate Japanese to English by voice
Japanese is spoken by about 125 million people. Speaklu translates spoken Japanese to English and English to Japanese live, and shows Japanese (kanji and kana) and English in the transcript.
Pick Japanese ↔ English
Choose the language pair once. Speaklu remembers it for the whole conversation.
Tap and speak
Speak Japanese or English naturally. Speaklu detects which language is being spoken.
Hear and read it
The translation is spoken aloud in a natural voice and shown as text in the transcript.
English to Japanese voice translation
Translation works both ways. Speak English and Speaklu says it in Japanese for the person in front of you, then translates their Japanese reply back into English. With two-way conversation mode you never have to switch directions manually.
Translate Japanese audio to English, live
Watching a Japanese video, livestream or podcast on your phone? Speaklu's live subtitle mode listens to the audio playing on your device and shows English subtitles in real time — on YouTube, TikTok, Instagram and other apps. Speaklu translates live audio as it plays; it does not translate uploaded audio files or recordings.
Japanese voice to English text
Every translation is also saved as text. The transcript shows what was said in Japanese and the English translation, so you can re-read a conversation, copy an address, or check a word you missed.
