Japanese Text to Speech

• Japanese text to speech on the video timeline

  Generate speech and the clip appears on a multi-track timeline next to your footage, not as a bare download. Trim it, split it and slide it against your cuts until the timing lands. This is the workflow gap pure TTS sites leave open, covered in more depth on add voice over to video.

• Five dedicated Japanese voices

  Four female voices and one male voice built for Japanese, with the pitch movement and mora rhythm the language needs. It is a deliberately small lineup: five reads that hold up inside a real edit, rather than a hundred variations of the same voice.

• Paste kanji, hiragana and katakana together

  Real Japanese mixes three scripts in one sentence, and the input box takes it exactly as written. Readings come from context, the way a person resolves them. For unusual personal names or brand words, spell the word in kana to force the pronunciation you want.

• Streaming generation, instant retakes

  Audio starts playing while it is still generating, so a full paragraph is auditioned in seconds. Rewording a clunky line and regenerating costs almost nothing, which changes how many takes you actually bother to try.

• Captions that render Japanese properly

  Japanese audiences expect on-screen text; TV and YouTube there lean on telop constantly. Auto-captions transcribe the voiceover with word-level timing, style it with any of 176 presets including karaoke fills, and kanji renders cleanly rather than as boxes. More on the japanese subtitle generator page.

• Bilingual subtitles for learners and global viewers

  Keep the Japanese voiceover and translate the subtitle text into any of 86 languages on Pro, or show original and translation together on screen. The translation applies to subtitles only; EchoWave does not dub the audio track into another language.

• Voice cloning when stock voices are not enough

  Cloning your own voice, or a narrator you have permission to use, is available as a paid feature. It keeps a series sounding like one person across dozens of episodes. Details on the voice cloning page.

• Audiograms and visualizers for audio-first posts

  If the script is a podcast intro or an announcement, pair the Japanese voice with one of 93 visualizer styles and publish it as a video. The AI voiceover generator page covers narration workflows across all 63 voices.

1. 1

   Paste your Japanese script

   Open the editor in any modern browser, add your footage or start with a blank canvas, and open the AI voice panel. Paste the script in kanji, kana or any mix of the two.

2. 2

   Pick a voice and generate

   Choose one of the five Japanese voices and generate. Playback streams while the audio renders, so you hear the read within seconds and can regenerate any line that lands wrong.

3. 3

   Fit the voiceover to the picture

   The clip sits on its own track. Split it at sentence breaks, slide sections to match your cuts, then run auto-captions so the spoken words appear as styled Japanese text on screen.

4. 4

   Export and publish

   Free exports are HD 720p MP4 with a small removable watermark badge. Paid plans remove the badge and add 1080p and up, plus audio-only MP3, M4A, WAV and FLAC downloads.

• Japanese language learners

  Hear how a sentence is actually pronounced instead of guessing from romaji. Paste homophones like 橋 and 箸 into context sentences and loop the playback to drill the pitch difference.

• YouTube narration in Japanese

  Voice an explainer or ranking video for a Japanese-speaking audience without recording a single take. Add telop-style captions so key phrases hit on screen the way local channels do it.

• Short-form video for TikTok, Reels and Shorts

  Vertical clips with a Japanese voice and karaoke captions with active-word fill. Resize the same edit to 9:16, 1:1 or 16:9 from a single project.

• E-learning and tutorials

  Course narration stays consistent when the same voice reads every module. Update a lesson by editing the script and regenerating, not by rebooking a voice actor.

• Localized product demos

  Voice your Japanese copy over the same screen recording you use in English. Templates with text placeholders can render variant versions in batches from a CSV upload.

• Announcements and accessibility

  Turn written notices into spoken video so the information reaches people who prefer listening. A steady neural voice reads long passages without drifting or tiring.
