LETR WORKS Unveils New LLM-Based YouTube Subtitle & Dubbing Service at Korea Creator Festa 2025

Empowering Creators for Global Expansion with AI-Driven Localization

LETR WORKS, an AI-powered content localization platform, showcased its latest large language model (LLM)-based YouTube subtitle and dubbing integration service at the 2025 Korea Creator Festa held at Songdo Convensia, Incheon, on July 11–12.

Designed to support content creators aiming to reach a global audience, LETR WORKS' new service offers an end-to-end solution for video localization. By combining advanced AI subtitle translation with natural-sounding AI voice dubbing, creators can now easily adapt their content for international viewers—without the need for separate tools or services.

Key Features of the LETR WORKS Solution:

• LLM-Powered Subtitle Translation: Context-aware AI provides accurate, fluent subtitles in multiple languages
• AI Voice Dubbing: Natural, expressive AI voiceovers that reflect the tone and pace of the original speaker
• One-Click Integration: Subtitle and dubbing workflows handled in a single project pipeline

A LETR WORKS spokesperson stated, “We’re lowering the language barrier for creators worldwide. Our goal is to simplify the localization process so that creators can focus on doing what they love—making great content.”

The Korea Creator Festa is one of the largest media exhibitions in South Korea, jointly hosted by the Ministry of Science and ICT and Incheon Metropolitan City. It serves as a platform for creators, tech companies, and industry leaders to connect, share, and innovate.

LETR WORKS is offering live demos of its solution at the event and inviting creators to participate in its upcoming beta testing program. On-site consultations and QR-based sign-up links are available for attendees.
