Bilibili, the Chinese video-sharing giant affectionately known as B Site (B站), is making waves with its newly unveiled AI-powered “Original Voice Translation” feature, according to reports. This innovative technology promises to revolutionize cross-lingual content accessibility on the platform, particularly for its gaming, tech, and anime-centric content.
Unlike traditional machine translation which can often sound robotic and detached, Bilibili’s AI offering focuses on delivering a fully localized experience that retains the unique vocal characteristics of its content creators, or “UPs” (uploaders). The core of this feature lies in its proprietary voice generation model which meticulously recreates a user’s distinctive voice, tone, and even characteristic speech patterns. It achieves this through sophisticated voice duration and emotion control methods, effectively separating emotional expression from the speaker’s identity. This ensures that the translated audio maintains the UP’s individual style while adapting seamlessly to the target language’s natural cadence.
Furthermore, the platform utilizes advanced video processing technology to intelligently erase and redraw original subtitles, achieving a near-perfect synchronization between translated speech and mouth movements. Addressing the inherent challenges of translating specialized terms from gaming and anime culture, Bilibili leverages deep learning techniques and a large language model-powered translation engine. This approach, they claim, boosts the accuracy of translating specialized jargon and cultural references to a remarkable 90%, effectively bridging the “humor gap” often encountered in cross-cultural content consumption.
Currently, the AI-powered translation supports bidirectional translation between Chinese and English, encompassing videos, live-streaming comments, and interface elements. The system handles hundreds of thousands of non-Chinese translation requests daily. Bilibili’s tech team has indicated plans to expand support to nearly ten languages, including Japanese and Korean, further solidifying its dominance within the ACG (Anime, Comics, and Games) cultural sphere.
Bilibili Chairman and CEO, Chen Rui, emphasizes that this feature is a critical step in realizing the platform’s vision of “content without borders.” Following the consolidation of its domestic and international apps and the company’s existing cultural localization expertise, this new AI capability signifies Bilibili’s technological maturity in the realm of cross-lingual content delivery.
Industry analysts suggest that Bilibili’s AI voice translation is a significant achievement. By optimizing for multiple objectives – translation accuracy, voice replication fidelity, and lip-sync precision – Bilibili has seemingly set a new technical benchmark for long-form video platforms.
For content creators, this feature significantly lowers the barrier to entry for international expansion, particularly for those whose content relies heavily on their unique vocal persona such as gaming commentators and animation reviewers. For viewers, whether they’re domestic users enjoying foreign content or international audiences exploring Chinese videos, the experience promises to be nearly seamless, eliminating the feeling of being separated by language.
