Spanish is one of the biggest audiences you can add without changing what you make. Here’s how to turn an English YouTube video into a Spanish one that still sounds like you, and the two ways to publish it.
Why Spanish first
- The Instituto Cervantes counts about 635 million potential Spanish speakers in 2025, including 520 million native speakers, the third-largest native-speaker community after Mandarin and Hindi (Instituto Cervantes, 2025).
- More than 120 million potential speakers live outside Spanish-speaking countries, including over 45 million in the European Union outside Spain (same source).
- YouTube says creators who upload multi-language audio tracks see, on average, over 25% of their watch time come from views in the video’s non-primary language (YouTube Official Blog).
Step 1: Pick the clip
- VideoVoice works on clips under 90 seconds. That covers any Short; for a long video, start with its strongest 60–90 seconds.
- One clear speaker and clean audio give the best result.
- Download your own upload from YouTube Studio (Content → Menu → Download) or use the original export from your editor.
Step 2: Dub it into Spanish
- Upload the clip to VideoVoice and choose Spanish as the target language.
- Your voice is cloned from the clip, so the Spanish version sounds like you. You don’t need to speak Spanish.
- The script is translated for meaning, not word for word. Background music is preserved and captions are generated.
- Download the finished MP4. It’s a clean file you own.
Step 3: Publish it, one of two ways
- As a new video: post the Spanish MP4 as a Short, or on a separate Spanish channel. The same file also works on TikTok and Instagram Reels.
- As an audio track on the original video: YouTube’s multi-language audio lets you add dubbed tracks to new or existing videos in YouTube Studio → Languages → Add language. This feature doesn’t create the dub for you; you upload a track you made, and it’s available to channels with Advanced features. The track has to be an audio-only file roughly the same length as the video (YouTube Help). Since VideoVoice clips are under 90 seconds, this route suits a clip you dubbed in full, and you’ll need to export the audio from the dubbed MP4 first.
- Viewers then hear the track that matches their preferred language and can switch in the player settings (same source).
