**AI-powered localization brings CS50 lectures to Portuguese- and Spanish-speaking learners, helping overcome the scaling challenges of traditional dubbing**

Lingopal, a leader in AI-powered localization, is collaborating with CS50, Harvard University’s Introduction to Computer Science course, to make its classes more accessible to learners around the world through multilingual AI dubbing.

The initiative begins with **Portuguese and Spanish**, two languages most requested by CS50’s community. Through the collaboration, Lingopal is localizing CS50’s long-form lecture content, part of the course’s commitment to making computer science education accessible to all - regardless of geography, economic status, or native language.

Making computer science education accessible to as many people as possible has long been a priority for CS50. While its content has been available online, free, as OpenCourseWare since 2007, language barriers still present a hurdle for learners whose primary language is not English.

Portuguese-speaking viewers represent approximately **5.5% of CS50’s total viewership**, and Portuguese ranks among the five most-used languages for YouTube’s automatic dubbing of CS50 content. With **CS50x em Português** now available and leveraging Lingopal - the CS50 team is looking forward to tracking how localized content - especially optimized localization - lifts engagement among Portuguese-speaking learners.

### **Solving the Challenge of Localization at Scale**

CS50’s long-form educational format presents a unique localization challenge. Individual lectures can extend beyond two hours, and the course contains more than 20 hours of lecture content that continues to evolve over time.

The CS50 team previously experimented with human translation of subtitles and explored emerging AI dubbing tools. However, producing human translations at this scale proved difficult to sustain, and some automated platforms impose duration limits that do not accommodate CS50’s longer format.

Lingopal’s AI-powered localization technology enables long-form video content to be dubbed without these constraints, creating an opportunity to localize complete educational experiences rather than individual short-form clips.

“Since 2007, CS50 has been freely available as OpenCourseWare to anyone online. But only in English. We experimented with human translation of subtitles some years ago, but it just didn't prove scalable, given the sheer volume and constant evolution of content in CS50. Fans though we are of humans, AI is even more impactful for translation of educational content at scale.”

### **Removing Language as a Barrier to Learning**

Demand for multilingual CS50 content extends beyond Portuguese and Spanish. According to the CS50 team, its audience analytics demonstrate interest in localized content across languages including Chinese, Hindi and Arabic.

The initial collaboration with Lingopal focuses on Portuguese and Spanish, with the potential to explore additional languages and content in the future.

For Lingopal, the collaboration demonstrates how AI localization can help address a challenge that extends well beyond media and entertainment: enabling organizations with large libraries of valuable educational content to make that knowledge accessible to more people without recreating their production workflows for every language.

“Some of the world's most valuable educational content is already available online, but availability and accessibility aren't always the same thing. Language can still determine who is able to fully participate. Our work with CS50 demonstrates the potential for AI localization to change that equation, making it possible to bring substantial libraries of long-form educational content to new languages at a scale that simply wasn't practical before.”

— **Bartell Cope, VP of GTM at Lingopal.ai**

Lingopal has increasingly focused on the role AI localization can play in education, where language can directly affect comprehension and access to learning.

### **Exploring the Future of Multilingual Education**

The collaboration highlights a broader opportunity for AI in online education. As universities, training organizations and educational platforms make more learning available digitally, tools like Lingopal help “unlock” those resources at-scale.

Rather than requiring separate production processes for each market, AI-powered localization can help organizations adapt existing libraries into multiple languages while retaining the instructor’s original delivery and learning experience.

For CS50 and Lingopal, the initial Portuguese and Spanish rollout provides an opportunity to explore how scalable localization can help high-quality educational content travel further and reach learners who may previously have been limited by language.

### **About Lingopal.ai**

Lingopal.ai provides AI-powered localization technology for live and on-demand video, helping organizations make content accessible to audiences across languages. Its technology supports AI dubbing, translation and captioning while preserving elements of the original speaker’s voice, tone and emotion. Lingopal works across media, sports, education and other content-driven industries to help organizations expand the reach and accessibility of their content.

### **About CS50**

CS50 is Harvard University’s introduction to the intellectual enterprises of computer science and the art of programming, designed for students with or without prior programming experience. Its educational content is also made freely available online through OpenCourseWare on edX at [https://cs50.edx.org](https://cs50.edx.org) and on YouTube at https://youtube.com/cs50, extending access to learners around the world.
