 ### Q：唤醒词一直没有反应？
 
-由于小爱音箱远场拾音音量较小，有时可能会识别不清，你可以调大 `config.py` 配置文件里的 `boost` 参数，然后重启应用 / Docker 试试看。
+如果唤醒词还是不敏感，可以先调低 `vad.threshold`，然后重启应用 / Docker 试试看。
 
 ```py
 APP_CONFIG = {
     "vad": {
-        # 小爱音箱录音音量较小，需要后期放大一下
-        "boost": 100,
-        # boost 调大后，语音检测阈值可能也需要一起调大些
-        "threshold": 0.50,
+        # 语音检测阈值（0-1，越小越灵敏）
+        "threshold": 0.05,
     },
     # ... 其他配置
 }
