Modern HR teams face a complex challenge: delivering training and internal communications that are engaging, effective, and accessible to employees across different countries, cultures, and languages.
More and more companies are turning to video as the preferred format for onboarding, compliance, soft skill training, and change communication. But if these videos remain available only in a single language, their impact is limited.
That’s where AI dubbing comes in – offering a scalable, high-quality solution to localize internal videos in 30+ languages, without traditional studio costs or delays.
Even in global companies with English as the official working language, comprehension and retention significantly increase when training is delivered in employees' native languages.
This is especially important for:
Health & safety training
Compliance and legal briefings
Onboarding programs for new hires
Product and process training
Soft-skill development (e.g., feedback, diversity, leadership)
Providing these materials in local language demonstrates cultural respect, improves understanding, and reduces the risk of miscommunication.
Translating a training video into 12 languages the traditional way involves:
Hiring multiple voice actors
Booking studio time
Manually syncing tone, speed, and timing
High production costs
Long lead times and slow updates
As a result, many companies either stick with subtitles – which fail to convey tone, emotion, and clarity – or limit themselves to English-only content.
