什么是 LiveAvatar？

LiveAvatar 与 Openclaw 技能的集成，为 AI 交互带来了类人化的维度。通过结合实时视频合成与语音识别，用户可以与智能体进行自然的面对面交谈。此技能利用 LiveAvatar 平台处理转录和对口型，确保用户语音与智能体回答之间的流畅衔接。

将其集成到您的工作流程中，可以让您超越文本界面的局限。化身会根据用户输入动态做出反应，提供更具参与感和共情力的体验。作为 Openclaw 技能生态系统的一个亮点，该工具通过先进的多模态能力缩短了数字智能与人类存在感之间的距离。

LiveAvatar 配置指南

要在 Openclaw 技能框架内使用此功能，首先从 LiveAvatar 控制面板获取免费的 API 密钥。然后，设置您的环境变量：

export LIVEAVATAR_API_KEY=您的API密钥

或者，将密钥添加到本地配置文件 ~/.openclaw/openclaw.json 中。配置完成后，您可以通过智能体调用以下命令启动界面：

OpenClaw LiveAvatar

Give your OpenClaw agent a face and voice! This skill launches a real-time AI avatar that you can talk to naturally using your microphone. The avatar listens to you, sends your speech to your OpenClaw agent, and speaks the response back with lip-synced video.

Powered by LiveAvatar - real-time AI avatar technology.
