停止服务

systemctl stop aispeech-engine-wrapper
systemctl stop dialog-domain-handlers
systemctl stop dialog-engine
systemctl stop dialog-audio-service

然后是修改配置文件，打开配置文件中的SeamlessUI的开关

/etc/dialog-engine/features/toggles.json

里把 “name”: “SeamlessUI” 的值改成 true

/etc/dialog-engine/features/dialog_variant_toggles.json

里把 “name”: “NaviSeamlessUI” 的值都改为 true，有两处，都改了就行。

改完配置文件，把ECU重启一次，保险起见。
