Frequently Asked Questions
Korean has 77+ million native speakers across South Korea and the Korean diaspora worldwide. K-drama, K-pop, and Korean gaming content have massive global followings — dubbing your content into Korean lets you tap into this engaged market or create content that resonates with Korean-speaking audiences directly.
Yes. SpeakSwap uses advanced AI voice synthesis built for Korean, producing natural intonation, authentic speech patterns, and correct pacing. The output sounds natural to Korean speakers rather than machine-translated.
Tutorials, vlogs, gaming commentary, product reviews, educational content, interviews, and podcasts all work. Multi-speaker clips are supported when you set the speaker count before submitting.
Yes. SpeakSwap uses AI vocal separation to isolate speech from the rest of the audio, dubs just the speech into Korean, then mixes the original background music back at full volume — keeping your content's atmosphere intact.
Yes — new accounts get free starter credits to try dubbing a short clip, no credit card required. For full-length videos, credit packs start at $6 and never expire.
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.
