+# Open-XiaoAI x Sherpa-ONNX
+
+> [!CAUTION]
+> 下面的教程和脚本正在开发整理中，请勿直接使用！🚨
+
+> [!IMPORTANT]
+> 本教程仅适用于 **小爱音箱 Pro（LX06）** 和 **Xiaomi 智能音箱 Pro（OH2P）**
+
+小爱音箱自定义唤醒词，基于 [sherpa-onnx](https://github.com/k2-fsa/sherpa-onnx)。
+
+## 刷机
+
+首先按照 [open-xiaoai](https://github.com/idootop/open-xiaoai) 里的教程将小爱音箱刷机， 然后 SSH 连接到小爱音箱。
+
+## 安装脚本
+
+在小爱音箱上安装启动脚本，然后重启小爱音响。
+
+```shell
+# 下载到 /data/init.sh 开机时自启动
+curl -L -o /data/init.sh https://gitee.com/idootop/artifacts/releases/download/open-xiaoai-kws/init.sh
+```
+
+## 设置唤醒词
+
+在你的电脑上克隆本项目，然后修改 `my-keywords.txt` 文件里的唤醒词。注意：
+
+- 仅支持中文唤醒词
+- 支持多个唤醒词，每行一个
+
+运行以下命令，更新 `keywords.txt` 配置文件：
+
+```shell
+# 你可能需要先安装 uv 👉 https://github.com/astral-sh/uv
+uv run keywords.py --tokens tokens.txt --output keywords.txt --text my-keywords.txt
+```
+
+将更新后的 `keywords.txt`（你的电脑）复制到 `/data/open-xiaoai/kws/keywords.txt`（小爱音箱），然后重启小爱音箱即可。
