1、使用微信小程序的同声传译功能

小程序平台-设置-第三方设置-插件管理-新增同声传译插件

小程序app.json文件配置

  "plugins": {
    "WechatSI": {
      "version": "0.3.5",
      "provider": "wx069ba97219f66d99"
    }
  },

小程序中使用

.xml

 <view class="action-box">
          <view class="action-btn" wx:if="{{!isPlaying}}" bind:tap="textToSpeech">播放</view>
          <view class="action-btn" wx:else bind:tap="pauseSpeech">暂停</view>
 </view>

.js

var plugin = requirePlugin("WechatSI")
 data: {
    audioContext: null,
    isPlaying: false,
    text:'这是一个微信小程序文字转语音的功能'
    }
      // 语音播报
  textToSpeech(e) {
    let name = e.currentTarget.dataset.name
    let that = this
    if (this.audioContext) {
      this.audioContext.destroy()
    }
    plugin.textToSpeech({
      lang: "zh_CN",
      tts: true,
      content: name,
      success: function (res) {
        that.audioContext = wx.createInnerAudioContext();
        that.audioContext.src = res.filename;
        that.audioContext.play();
        that.setData({
          isPlaying: true
        })
        that.audioContext.onEnded(() => {
          //播放结束
          that.setData({
            isPlaying: false
          })
        })
      },
      fail: function (res) {
        console.log("fail", res)
      }
    })
  },
  // 暂停语音播报
  pauseSpeech() {
    console.log(111,this.data.isPlaying,this.audioContext);
    if (!this.data.isPlaying) return;
    this.setData({
      isPlaying: false
    })
    this.audioContext && this.audioContext.pause();
  },
