Enhancing E-Learning with Automated Subtitle Solutions
Challenge
The e-learning platform, which hosts thousands of instructional videos on YouTube, has faced a number of serious difficulties in making content accessible to a global audience. One of the key challenges was creating subtitles for each video. The manual process of developing subtitles for video content was not only very time-consuming, but also expensive, which hindered scaling possibilities. Dozens and sometimes hundreds of new videos were added to the platform every month, which made manual generation of subtitles almost impossible for effective growth.
In addition, the need to meet the requirements of students with hearing impairments, as well as those for whom the language of the video content was not their native language, posed another task: it was necessary to maintain accurate, multilingual subtitles. The platform faced a challenge not only in creating these subtitles, but also in making them accurate and tailored to each video, which would not have been possible without an effective automated solution.
Solution

Lingvanex AI-powered Automatic Subtitling uses advanced speech processing and machine translation technologies, which makes subtitle creation not only fast and cheap, but also scalable. Now, thanks to the integration with the platform, subtitles were generated automatically for each new video, including support for multiple languages, which made it possible to cover the needs of a wide international audience.

Moreover, thanks to the improved accessibility of content, students with hearing impairments and those for whom the language was not their native language found the platform's materials more understandable, which significantly improved the quality of their learning. Automation of the process allowed to reduce the cost of creating subtitles by 60%, which gave the platform the opportunity to reinvest the saved funds in the creation of new content.
