I posted a tutorial last month that hit 40K views in the US, then a subscriber from Mexico City commented asking if I had a Spanish version. I didn't. So I spent three hours trying to caption it manually, gave up, and found this tool instead. Uploaded my 8-minute video, picked Spanish, and got back a dubbed track plus the SRT file in about twelve minutes. The voice actually matched my tone—wasn't robotic. Reuploaded it, added 'Español' to the title, and that same video pulled another 23K views from Spain and Argentina in two weeks. Now I run every English video through this before I even think about posting.
AI recognizes the original speech and translates it, no manual alignment needed.
Subtitles and speech match sentence by sentence, frame-accurate.
Only the speech is replaced — ambient sound and music stay intact.
Local free engines or cloud engines (Whisper, DeepSeek, Kimi and more).
Dubbed video, SRT, VTT or plain text — whatever your workflow needs.
Local mode keeps your files on your computer, never uploaded.
Yes. The tool separates your voice from the audio track, replaces it with the Spanish voiceover, and keeps your BGM, game sounds, or ambient noise exactly as they were.
Absolutely. I always download the SRT first, fix a couple technical terms my niche uses, then re-upload it so the dub matches my exact wording.
YouTube doesn't let you swap audio on the same video, so I upload it as a new video with 'Español' in the title, then link both versions in the description and pinned comment.
SpeakVid uses industry-leading recognition and translation models (Whisper, DeepSeek, Kimi and more), with multi-level fallback to keep output reliable.
Most tasks finish in minutes. A 10-minute video typically completes in 2-5 minutes depending on length and engine.
