Frequently Asked Questions
Most online courses are recorded in English, but 75% of internet users prefer content in their native language. Dubbing your course into Spanish, Portuguese, French, Arabic, or other languages dramatically expands your student reach — without re-recording or hiring voice actors.
SpeakSwap supports 140+ languages including Spanish, French, German, Portuguese, Arabic, Hindi, Chinese, Japanese, Korean, Russian, and more. Each language includes multiple natural AI voices so your course content sounds clear and engaging.
A 10-minute lecture typically dubs in 5–10 minutes on our GPU servers. Longer lectures or full courses take proportionally longer. Pay-as-you-go pricing means you only pay for what you dub — no subscription required.
Yes. SpeakSwap uses AI vocal separation to isolate your voice from background audio, dubs only the speech, then blends them back. Music beds, sound effects, and ambient audio stay untouched in the final output.
Yes — new accounts get free starter credits to try dubbing a short clip, no credit card required. For full course lectures, pay-as-you-go packs start at $6. Credits never expire, so you can dub lecture by lecture at your own pace.
Yes. In video dubbing, smart lip sync is optional for eligible clips longer than 20 seconds and up to 90 seconds. SpeakSwap detects speakers and recurring faces, then asks you to confirm speaker-to-face matches before rendering. It is designed for real talking-head video with visible, moving faces — not a still image, slideshow, or image-to-video animation. Transcription, text-to-speech, and other audio-only tools continue to work without lip sync.
Use real talking-head footage where a person is visibly speaking and the face moves naturally. SpeakSwap can dub a still-image video as audio, but it does not animate still pictures, slideshows, or image-to-video portraits. Turn smart lip sync off for those sources and use the audio dub instead.
