All your video translation questions answered
How does English to Spanish translation work?
Upload your English video and Synthesia's AI transcribes the audio, translates it into Spanish, clones the speaker's voice, and re-syncs their lip movements, producing a natural Spanish dub without a studio or voice actor.
Is it free to translate my video from English to Spanish?
Yes. Your first minute is free to translate right here, and you can dub longer videos for free inside the app.
Will English and Spanish subtitles be generated for my video?
Subtitles are auto-generated in the language of your script, so you get both Spanish and English captions that viewers can toggle on or off in the Multilingual Player.
Will lip movements match the Spanish audio if the video was filmed in English?
Yes. When lip sync is enabled, Synthesia reshapes the speaker's mouth movements to fit the Spanish audio, so the delivery looks like it was recorded in Spanish from the start.
Will my translated video keep the original voice in Spanish?
Yes. Voice cloning carries the original speaker's tone and character into the Spanish version, so it still sounds like them.
How accurate is the AI English to Spanish translation?
Synthesia delivers highly accurate Spanish translations that preserve meaning and speaker identity, and you can edit the transcript directly for technical terms, brand names, or regional phrasing before you export. You can also edit translations after video generation.
Can I translate YouTube videos from English to Spanish
Yes. Paste a YouTube link and Synthesia handles transcription, translation, and lip sync automatically, with no download or upload needed.
Can I translate a podcast or multi-speaker video into Spanish?
Yes. Synthesia detects each speaker, dubs them into Spanish with their own cloned voice, and keeps every part lip-synced. Ideal for podcasts, interviews, and panels.
