诀窍是处理 PlaybackNearlyFinished 事件.developer.amazon/de/docs/alexa-voice-service/audioplayer.html#playbacknearlyfinished

在当前播放的音频流结束前不久触发此事件.使用另一个具有 ENQUEUE 行为的 audioPlayerPlay 指令响应该事件.这将无限循环您的音频，直到它被例如中断.AMAZON.StopIntent.

This event is fired shortly before the currently playing audio stream is ending. Respond to the event with another audioPlayerPlay directive with behavior ENQUEUE. This will infinitely loop your audio until it gets interrupted by e.g. the AMAZON.StopIntent.

高级:如果你想要一个有限循环，比如你的音频的十倍，使用 audioPlayerPlay 指令的标记从十开始倒计时.一旦计数器归零，就不要将另一个音频加入队列.但一定要在这种情况下做出回应，即使这只是一个空洞的回应.否则会出现超时错误等.

Advanced: if you want a finite loop, say ten times your audio, use the token of the audioPlayerPlay directive to count down from ten. Once the counter hits zero, just don't enqueue another audio. But be sure to respond something in this case, even if it's just an empty response. Otherwise you will get a timeout error or the like.
