ByteDance Unveils Seed Audio 1.0, Revolutionizing Audio Creation with New Speech-to-Content Tool
Recently, ByteDance introduced Seed Audio 1.0, its new audio creation model, marking a significant advancement in AI audio generation. This update moves the technology beyond basic speech synthesis to enable the creation of fully integrated sound scenes. The model is currently available for creators to test at the Volcano Fangzhou Experience Center.
Traditionally, producing audio content on par with that used in films and television required multiple separate models to generate vocals, sound effects, and ambient noises, which were then manually combined. This approach was time-consuming and made it challenging to maintain consistent storytelling throughout the audio. Seed Audio 1.0 addresses this issue by integrating all audio elements within a single framework rather than simply combining pre-made materials, allowing it to produce complete sound works that support end-to-end storytelling.
According to the official details, Seed Audio 1.0 features three key capabilities. First, it offers precise temporal-spatial control, enabling creators to set the exact timing for dialogue and sound effects with accuracy down to 100 milliseconds, which is ideal for video dubbing and advertising production. Second, it delivers stable voice performance, supporting zero-shot generation and extended audio output while preserving the character’s voice characteristics. It can also convey a range of emotions such as anger or joy naturally, and even allow one voice to represent multiple characters. Third, it provides robust multilingual support for over 20 languages, including Chinese, English, and Japanese, ensuring the voice sounds natural and fits the local linguistic patterns of each language.
Evaluation results show that the model performs well in nine common creative scenarios, with audio availability exceeding 90%. Additionally, its naturalness MOS score for multilingual generation typically falls above 4 points, which is considered an excellent rating.
By evolving from a tool that can only generate speech to one that can create complete audio content, Seed Audio 1.0 lowers the barriers to producing high-quality audio material. The development team plans to further enhance the model by incorporating multimodal inputs such as video references and exploring controllable translation features. They also aim to continue improving long audio and track generation capabilities, helping creators turn their conceptual sound ideas into fully functional audio works more efficiently.
