(headquartered in Chiyoda City, Tokyo; Japan & Korea General Manager: Hajime Tamura; hereinafter "ElevenLabs") to launch a multilingual dubbing support service for enterprises using AI voice technology.

In recent years, the use of video in corporate activities has expanded significantly. Videos and audio content are now widely used for product and service introductions, sales pitches, internal training, recruitment, investor relations (IR), webinars, and more. As a result, demand for multilingual content targeting overseas offices and international customers has increased. However, practical implementation in enterprises requires consistent terminology, appropriate expression, tone alignment with brand identity, and rigorous quality control of final deliverables.

Since its founding in 1963, To-in has supported multilingual expansion for companies across diverse industries, including manufacturing. By combining its practical translation expertise and quality management insights—built through experience with over 100 languages—with ElevenLabs’ advanced AI voice technology, To-in enables simultaneous deployment across multiple languages with high-quality dubbing. ElevenLabs’ AI voice technology is characterized by natural, human-like speech expression and offers flexible control over voice quality, speaking speed, and tone—making it easier to design clear, context-appropriate expressions that meet enterprise content requirements.

Leveraging this combined technology and expertise, the service supports enterprise multilingual expansion, including both major and region-specific languages. It broadly supports languages across major European, East Asian, South Asian, Southeast Asian, and Middle Eastern and surrounding regions—enabling flexible multilingual deployment beyond just major languages.
