android - app在后台以及锁屏状态下如何播放语音提醒如何实现？

Question

最近接了一个项目，有一个需求是app 在后台或锁屏状态下，还能够播放语音提醒。不知道是如何实现的？类似嘀嘀打车的锁屏状态下的语音播报功能。

目前遇到的问题是 Android 端在锁屏状态下语音提醒会被系统通知的声音给冲突，ios 端无法做到锁屏后播报语音，由于没有触发点。

Answer 1

The notification I originally used was notification. Although I used the system sound as the sound, it should be possible to customize the sound.
You can try it yourself

Answer 2

You can try iFlytek Voice SDK. Many maps such as Amap use this kind of SDK. Convenient and fast
