Question

我需要在我的alexa技能中执行以下一系列事件，我目前无法确定如何执行此操作。

播放一些音频剪辑（超过90秒）。
询问用户是否准备好接收下一个音频片段。
根据要求播放另一个音频片段。
根据需要重复。

我对＃1有以下意图：

"PlayWarmUp": function(){
        console.log("play warm up intent fired");

        if (this.event.context.System.device.supportedInterfaces.Display) {
            //play warm up video
            const builder = new Alexa.templateBuilders.BodyTemplate6Builder();
            const template = builder.setTextContent(makeRichText('<font size="7">Are you ready?</font><br/><br/><br/><br/>')).build();
            let meta = {
                title: "Warmup",
                subtitle: null
            };
            this.response.playVideo(videoURL, meta).renderTemplate(template).hint("'Yes', or 'No', or 'Ready'");
            //switch state to workout since we want to handle their responses to the are you ready screen, which is in the WORKOUT state
            this.handler.state = states.WORKOUT;
            this.emit(":responseReady");
        } else {
            // Audio only
            //
            console.log("Audio only for play warm up");
            this.response.shouldEndSession(false);
            this.response.audioPlayerPlay('ENQUEUE', warmupAudioURL, 'warmup-audio-token', 'previous-token', '0');

            this.handler.state = states.WORKOUT;
            audioState = states.WARMUP;
            this.emit(":responseReady");
        }
    }

亚马逊为这样的音频事件提供内置意图：

const audioHandlers = {
    'PlaybackStarted' : function() {
        console.log('Alexa begins playing the audio stream');
        this.emit(':responseReady');
    },
    'PlaybackFinished' : function() {
        console.log('The stream comes to an end');
        console.log("audioState: ", audioState);
        console.log("this ", this);
        console.log("context: ", this.context);

        if (audioState === states.WARMUP) {
            console.log("audio state is warm up...");

            // This doesn't work. It does nothing.
            //
            this.handler.state = states.WORKOUT;
            this.emitWithState("WORKOUT");
        }
    },
    'PlaybackStopped' : function() {
        console.log('Alexa stops playing the audio stream');
        this.emit(':responseReady');
    },
    'PlaybackNearlyFinished' : function() {
        console.log('The currently playing stream is nearly complate and the device is ready to receive a new stream');
        this.emit(':responseReady');
    },
    'PlaybackFailed' : function() {
        console.log('Alexa encounters an error when attempting to play a stream');
        this.emit(':responseReady');
    }
};

上述代码不起作用。我无法打电话给＆＃34;锻炼＆＃34;音频结束时的意图。

documentation州：

我还看过使用SSML，但emitWithState()在讲话结束前发光，只允许90秒的音频。

您无法播放和录制音频，然后向用户询问某些内容，这没有任何意义。这应该是一个基本的对话功能。有人解决了这个问题吗？
