What the AI video translator doesNatural dubbing, subtitles, voice cloning, long-form support, and prepaid credits.v
SpeakSwap can transcribe speech, translate the meaning with context, generate dubbed speech with voice cloning, preserve background audio where possible, and return usable audio or video output without forcing a monthly subscription. It is strongest when the video has real creator constraints: music beds, vlogs, interviews, courses, fast speech, and source audio you still want to feel recognizable.
- Naturalness: context-aware translation instead of literal phrasing.
- Timing: pacing and phrasing that stay close to the original rhythm.
- Background: music and ambience preserved where the source allows it.
- Voice: accent-aware voice cloning where source audio allows it.
- Billing: prepaid credits, no required subscription, no watermark on completed exports.

よくある質問
An AI video translator turns speech in a video into another language using transcription, translation, and either subtitles or dubbed speech. SpeakSwap focuses on creator-ready video dubbing with voice cloning, context-aware translation, and pay-as-you-go credits.
Yes. Upload a video or paste a supported YouTube URL, choose English as the target language, and generate English dubbed audio. SpeakSwap supports 100+ source languages into English.
Dubbing is better when viewers need to listen in the target language, especially for tutorials, podcasts, courses, interviews, and long-form video. Subtitles are better when silent viewing, exact text review, or fast edits matter more.
No. SpeakSwap uses free starter credits and credit packs starting at $6. One balance works across all six tools, failed jobs do not spend credits, and completed exports are not watermarked.
はい。動画吹き替えでは、20秒を超え90秒以内の対象クリップでスマートリップシンクを任意で利用できます。SpeakSwapが話者と繰り返し映る顔を検出し、レンダリング前に対応関係を確認できます。文字起こし、テキスト読み上げなどの音声ツールはリップシンクなしで引き続き利用できます。
