Bilibili officially launched its self-developed "AI Voice Translation Function" to address the issue of content exchange between domestic and international audiences after the merger of the international version of the App with the domestic version in May. This technological innovation provides a new solution for overseas users to experience Chinese games, technology, and anime content.
This function is now available to overseas users, with the first support being English translation. Bilibili's AI translation system offers two core capabilities: visual and audio. In the visual aspect, it automatically removes original Chinese subtitles and replaces them with English, translates live comments in real-time, and changes the language of various interface buttons.
Audio translation is the biggest highlight of this function. Unlike traditional machine voice translation, Bilibili's AI system can retain the original voice tone, vocal characteristics, and speaking habits of the content creators, allowing overseas viewers to hear English dubbing that still carries the personal style of the creator. This technological breakthrough effectively solves the problem of rigid machine translation voices and lack of emotional expression.
The Bilibili technical team stated that the biggest challenge this function faces is achieving "accurate preservation of the original style and perfect alignment of voice duration" in content areas with a high concentration of proper nouns and internet slang, such as games and anime. These specialized content often include a large number of specific terms, cultural references, and conventional expressions, which can lead to meaning distortion or cultural barriers if directly translated.
To solve this problem, Bilibili has built a translation engine based on large language models, using adversarial reinforcement learning technology to drive model training. More importantly, the team introduced Deep Research deep mining technology to specifically optimize the translation challenges of proper nouns and popular internet slang, ensuring that the final translation accurately conveys the original meaning while maintaining the original cultural flavor.
The launch of this technology is closely related to Bilibili's internationalization strategy. In May this year, Bilibili decided to remove the independent international version of the App and integrate overseas users into a unified platform. While this adjustment simplified the product architecture, it also brought new challenges in content localization. The timely introduction of the AI Voice Translation Function provides important technical support for this strategic transformation.
From the user experience perspective, the translation technology that preserves the original voice characteristics of content creators can maintain the emotional connection between creators and their audience. For overseas fans who are used to the style of specific creators, even if the language changes, familiar voice traits can still bring a sense of familiarity and recognition.
Bilibili revealed that in the future, it will add more language support, such as Japanese, to the AI Voice Translation Function according to market demand, continuously expanding its adaptability in the overseas market. This indicates that Bilibili not only sees the translation function as a tool to solve current issues, but also as a core technological capability for long-term international development.
In terms of technical implementation, the application of adversarial reinforcement learning reflects Bilibili's deep investment in AI technology. This training method allows the model to continuously optimize its performance during translation, gradually improving its understanding of complex contexts and cultural content. The introduction of Deep Research technology demonstrates Bilibili's deep understanding of the characteristics of vertical content areas.
From an industry perspective, Bilibili's AI Voice Translation Function represents a new approach to the internationalization of content platforms. Traditional content exports often rely on manual translation or simple machine translation, which is costly and inefficient. AI-driven real-time translation technology provides a feasible solution for cross-language dissemination of large-scale content.
The successful application of this function may have a demonstration effect on the entire video content industry. With the growth of global content consumption demand, AI translation technology that maintains the characteristics of original creators will become an important competitive advantage for content platforms.
For the overseas dissemination of Chinese cultural content, Bilibili's technological innovation holds significant importance. Chinese content in fields such as games, animation, and technology often carries rich cultural connotations. Accurate translation is not only a language conversion but also a bridge for cultural transmission. Through AI technology, high-quality content localization helps Chinese original content gain better acceptance in overseas markets.
