1、安装speak-tts包

npm install speak-tts

2、在页面中引入

import Speech from 'speak-tts'

3、初始化以及实现

data () {
    return {
      speech:null
    }
},
mounted(){
   this.speechInit();
},
methods:{
   speechInit(){
     this.speech = new Speech();
     this.speech.setLanguage('zh-CN');
     this.speech.init().then(()=>{
        console.log('语音播报初始化完成...')
      })
   },
   
   //语音播报
   speak(){
     this.speech.speak({text:"语音播报测试"}).then(()=>{
       console.log("播报完成...")
     })
   }
}
