What Languages Are Supported for AI Video Translation?

GeckoDub translates video into 70+ languages and layers 148+ regional accents on top of them — covering every major advertising market in Europe, the Americas, Asia-Pacific and MENA.

The languages most used for video ads

• Western Europe — Spanish, German, French, Italian, Portuguese, Dutch
• Central & Eastern Europe — Polish, Czech, Romanian, Hungarian, Ukrainian, Greek, Croatian, Slovak, Bulgarian
• Nordics — Swedish, Danish, Finnish, Norwegian, Icelandic
• Americas — Brazilian Portuguese, Latin American Spanish, Canadian French
• Asia-Pacific — Japanese, Korean, Mandarin, Cantonese, Hindi, Tamil, Thai, Vietnamese, Indonesian, Malay, Filipino
• Middle East & Africa — Arabic, Turkish, Hebrew, Swahili, Afrikaans, Amharic

Accents matter as much as languages

A language is rarely one market, so the accent library goes deepest where advertisers need it:

• Spanish — 22 variants, including Spain, Mexico, Argentina, Colombia, Chile, Peru and US Spanish
• Arabic — 16 country variants, from Egypt and Saudi Arabia to Morocco and the UAE
• English — 16 variants (US, UK, Ireland, Australia, Canada, India, Nigeria, South Africa and more)
• Chinese — 9 variants, including Mandarin, Cantonese and Taiwanese Mandarin
• French — France, Canada, Belgium, Switzerland
• German — Germany, Austria, Switzerland
• Portuguese — Brazil, Portugal

Choosing the right variant is what makes a translated ad read as local rather than imported. A Mexican voice in an Argentine campaign, or European Portuguese in Brazil, gets noticed within a sentence.

Quality is not identical across the list

High-resource languages — Spanish, Portuguese, German, French, Italian, Japanese — produce the most natural voice cloning and the most idiomatic translation. Smaller languages are fully supported but can sound flatter, so review those in Smart Translation Control before you put budget behind them.
