Question

我使用自适应语音（文本到语音），并在数组中创建了一些简单的数据，并用promise遍历了它，但是当我将解析方法放入自适应语音的方法onend时，不是语音的结尾，它会调用下一个数据。请查看我的代码。

var data = [
 {'textTH': "สวัสดี ค่ะ", 'lang': "Thai Female", 'textEN': "Hello", 'langEN': "US English Female"},
 {'textTH': "สวัสดี ค่ะ", 'lang': "Thai Female", 'textEN': "Hello 2", 'langEN': "US English Female"}
];

var j = data.length;

function step2(i){
    return new Promise(function(resolve, reject){
    if (typeof data[i] == 'undefined'){
            reject("out of rang");
    }
    else{               
      var runEnglistSpeech = function () {
        responsiveVoice.speak(data[i].textEN, data[i].langEN, { rate: .7, onend: resolve()});
        console.log("done >>>> " + i);        
      };
        responsiveVoice.speak(data[i].textTH, data[i].lang, { rate: .9, onend: runEnglistSpeech });      
    }
  })
}

(async () => {
    for (let i = 0; i < j; i++) {
        await step2(i);
       }
})();

Answer 1

我正在尝试超时，它可以工作，但是我想对此有任何选择

setTimeout(function(){ resolve(); }, 6000);

Answer 2

您的代码正在运行。更改 responsiveVoice.speak(data[i].textEN, data[i].langEN, { rate: .7, onend: resolve()}); 至 responsiveVoice.speak(data[i].textEN, data[i].langEN, { rate: .7, onend: resolve});

响应语音js如何与promise一起工作？
