Tencent Hunyuan announced Hy Realtime, a real-time speech model that improves intent understanding, instruction following, and human-like expression. It adds agentic tool calling and singing capabilities. The model is available in the latest Yuanbao app via the 'Chuyu' voice in voice calls, and in Tencent customer service. A web demo is available at https://rtcube.cloud.tencent.com/component/hunyuan/index.html. Tencent Cloud API access is planned for the near future. Future iterations will focus on duplex interaction, long-term personalized memory, and foreground-background agent interaction.
Hy Realtime handles incomplete or self-corrected speech by using conversation context to infer intent, improving understanding accuracy. It supports multi-turn instruction following and context management for stable performance in long conversations. The model adds agentic tool calling, enabling it to invoke external tools during interactions, and can sing.
Tencent's integration of Hy Realtime into Yuanbao and customer service gives it a direct distribution channel to millions of users, potentially reducing reliance on third-party speech models and lowering per-interaction costs for Tencent's own products.
Hy Realtime can improve customer service efficiency and user experience in voice interfaces, potentially reducing operational costs for Tencent and its cloud customers. The singing capability may differentiate consumer products like Yuanbao.
Tencent plans to enhance duplex interaction, long-term personalized memory, and foreground-background agent interaction. Watch for the Tencent Cloud API release and any benchmark results or third-party evaluations of Hy Realtime's speech quality and tool-calling reliability.
