Let me compile the analysis. --- ## 分析报告：SimpleRouterAgent 语言检测改动潜在问题 ### 1. `detectLanguageSimple()` 实现分析 ```java private String detectLanguageSimple(String text) { if (text == null || text.isEmpty()) { return "English"; } int chineseCount = 0; for (char c : text.toCharArray()) { if (Character.UnicodeScript.of(c) == Character.UnicodeScript.HAN) { chineseCount++; } } return chineseCount > text.length() / 4 ? "Chinese" : "English"; } ``` **规则：** 遍历文本每个字符，统计 Unicode Script 为 `HAN`（汉字）的字符数。如果汉字数量超过文本总长度的 1/4，判定为中文，否则为英文。 **关键点：** - "一二三" 中每个字都是 `HAN` 字符（是的！"一""二""三" 都是汉字，Unicode Script = HAN） - 只看 CJK 汉字，不看标点、空格、数字等 - 是一个粗粒度的启发式检测 ### 2. 场景分析 #### 场景 A：... |

Retell 把 "123" 转成 "一二三" 的场景分析 "一二三" → 每个字符都是汉字（HAN），chineseCount = 3, text.length = 3, 3 > 3/4 = 0.75 → 返回 "Chinese" LLM 看到纯中文数字 "一二三"，大概率也会检测为 Chinese。所以两者一致，不会触发新的覆盖逻辑。 ... |
