Translate video to EnglishTranslate any video into English, with voices that act.

Spelo turns a film, series or documentary in any language into an English dub. Each speaker keeps a voice of their own and the way they delivered the line, over the video's original music and sound.

One scene, up to two minutes, in one target language.

A drama line, Spanish to English.

English-speaking audiences are quick to switch off a flat dub. The anger and the hurt in this line are what the scene is about, so both are carried into the English performance.

What makes an English dub hard

English-speaking audiences are used to watching in their own language, and they notice a bad dub at once.

  • Flat voices

    Robotic or overly calm delivery is the most common complaint about dubbed films.

  • Idioms and culture

    A literal translation of a joke or an idiom lands flat or makes no sense.

  • Names and places

    Names must be pronounced and spelled consistently from the first scene to the last.

  • Mixed audio

    Many videos arrive with music and effects mixed into the speech.

How Spelo makes an English dub

  • Delivery first

    Spelo hears how each line was said and performs the English the same way.

  • Written, not transliterated

    The English is written for the scene, so jokes and idioms read as natural English.

  • A brief for the whole video

    Names, places and who is who are fixed before the first line is written.

  • Original sound kept

    Voices are separated from the music and effects, which stay from the original.

How a project runs

Spelo makes the dub and the mix. Your team reviews every line and exports.

Send your film and notes

Share a video file or a link. Add who's-who notes if you have them, so names and relationships are right from the first line.

Choose the target language and your audience

Spelo creates the dub and mix

Every line is written for its scene, voiced with the original emotion and mixed over the film's own sound.

Review and fix lines in Studio

Your team signs off the language, changes any line and re-voices it in seconds.

Export your finished MP4

Download the dubbed video once your team is happy with every line.

Questions

Which languages can be translated into English?

Any language Spelo can hear, including Spanish, Japanese, Korean, Hindi, Arabic, French and German.

Does the English voice sound like the original speaker?

It can: a voice can be modelled on the original speaker's, where you hold the rights, or picked from a large voice library.

Is this subtitles?

No. Spelo makes a dubbed soundtrack, so viewers hear English instead of reading it.
