HomeTongyi Lab Debuts Fun-CosyVoice3.5 and Fun-AudioGen-VD Speech Models
Today, Tongyi Lab officially unveiled two FreeStyle-enabled voice generation models: Fun-CosyVoice3.5 and Fun-AudioGen-VD. This launch signifies a paradigm shift in speech synthesis, moving from reliance on preset tags to a new framework based on natural language instructions. It achieves a deeply interactive experience, enabling users to "generate speech freely with a single sentence."
Regarding technical architecture and functional upgrades, Fun-CosyVoice3.5 emphasizes multilingual voice cloning and nuanced expression, now adding support for four new languages, including Thai and Indonesian. By integrating DiffRO and GRPO reinforcement learning technologies, the model achieves substantial improvements in prosody and audio quality similarity. Its error rate for rare characters has decreased from 15.2% to 5.3%, and initial packet delay has been reduced by 35%. Complementing this, Fun-AudioGen-VD focuses on sound design and scenario modeling. It supports precise, instruction-based control over gender, emotion, and spatial acoustics, enabling the simulation of complex, integrated scenarios—from a "crazy villain" to a "noisy café" ambiance.
From an industry trend perspective, Tongyi Lab 's initiative elevates speech generation from a simple conversion tool to a full-fledged creation tool. This descriptive and programmable digital expression capability directly empowers sectors like film, gaming, and AI avatars. It reduces content creation costs while significantly expanding the semantic richness of human-computer interaction.
