Frequently Asked Questions
Spanish is the world's second most spoken language natively, with 500+ million speakers across 20+ countries. Dubbing your content into Spanish opens access to the largest Spanish YouTube audience — in Latin America, the US Hispanic market, and Spain — without requiring viewers to read subtitles.
Yes. SpeakSwap uses advanced AI voice synthesis for Spanish, supporting both Castilian (Spain) and Latin American accents. It handles regional vocabulary, intonation patterns, and natural pacing — producing audio that sounds native, not robotic.
Tutorials, vlogs, product reviews, gaming commentary, educational content, interviews, and podcasts all work. For multiple speakers, give your best count estimate before submitting; clean turn-taking gives the strongest separation.
Yes. SpeakSwap uses AI vocal separation to isolate speech from background audio, dubs the speech into Spanish, then mixes the original background music back at full volume — so your content feels professional with no audio gaps.
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.
