技巧是处理 PlaybackNearlyFinished 事件。 developer.amazon。 com / de / docs / alexa-voice-service / audioplayer.html＃playbacknearlyfinished

此事件在当前播放的音频流结束前不久触发。 使用行为为 ENQUEUE 的另一个 audioPlayerPlay 指令响应事件。这将无限循环您的音频，直到它被例如 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：如果您想进行有限循环，例如说十倍于音频，请使用 audioPlayerPlay 指令的标记从10开始递减计数。计数器归零后，就不用再排队其他音频了。但是在这种情况下，请务必做出回应，即使只是空洞的回应。否则，您将收到超时错误等。

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.
