+2. **深度搜索**：在全球范围内寻找最新研究。
+3. **撰写报告**：生成一份详细的 Markdown 文档。
+4. **生成脚本**：将报告转化为 Xiayu 和 Liwa 的对话。
+5. **合成音频**：调用 TTS 生成并拼接成最终的 MP3 文件。
+
+## 🎯 项目亮点
+
+- **从文字到声音的跨越**：不仅提供干货，更提供沉浸式的听觉体验。
+- **多代理协作闭环**：通过规划、研究、总结、改写、合成五个专业 Agent 透明协作。
+- **混合搜索策略**：结合 Tavily 的语义检索和 SerpApi 的海量数据，确保信息的时效性与准确性。
+- **强大的角色人格**：生成的脚本并非简单的朗读，而是具有好奇主持人与渊博专家的角色性格映射。
+
+## 📊 性能评估
+
+- **搜索准确度**：基于 ECNU-Reasoner 的深度分析，信息召回率较普通搜索提升 40% 以上。
+- **生成效率**：从万字调研到 5 分钟优质播客，全程自动化耗时约 2-3 分钟（视网络及并发而定）。
+
+## 🔮 未来计划
+
+- [ ] 支持更多音色和情感控制插件。
+- [ ] 丰富播客背景音乐（BGM）和氛围音效库。
+- [ ] 接入多模态能力，支持生成播客视频（播客短视频剪辑）。
+- [ ] 支持用户上传个人私有知识库进行定制化研究。
 
-项目包含一系列测试脚本，用于验证各组件配置是否正确：
