Use the speak-tts plug-in in Vue to implement voice broadcast (TTS/text-to-speech) after clicking the button

scenario

speak-tts plug-in

https://www.npmjs.com/package/speak-tts (Learning video sharing: vue video tutorial)

Click the button to trigger the voice broadcast and broadcast the specified text content.

Why can’t automatic voice broadcast be implemented?

Since April 2018, the Chrome browser has completely banned the automatic playback function of audio and video in desktop browsers.

Strictly speaking, Chrome does not allow audio to be played before the user triggers the web page.

Not only that, when the page is loaded, the user does not have active interactive behaviors such as click, dbclick, touch, etc.

If you use js to directly call the .play() method, chrome will throw The following error occurred: Uncaught (in promise) DOMException;

Implementation

1. Refer to the official instructions to install dependencies

npm install speak-tts

2. Introduce

import Speech from 'speak-tts'

3 into the page. Declare the speech object

  data() {    return {
      speech: null,
    };

4. Load the page After calling the initialization method

mounted() {
    this.speechInit();
  },
  methods: {
    speechInit() {
      this.speech = new Speech();
      this.speech.setLanguage("zh-CN");
      this.speech.init().then(() => {});
    },

5. Add a button to the page

<el-button type="success" @click="speakTtsSpeech">speak-tts语音播报</el-button>

6. Call the playback method in the button click event

    speakTtsSpeech() {      this.speech.speak({ text: "公众号:霸道的程序猿" }).then(() => {
        console.log("读取成功");
      });
    },

7. Complete sample code

<script>
import Speech from "speak-tts"; // es6
export default {
  name: "SpeechDemo",
  data() {
    return {
      speech: null,
    };
  },
  mounted() {
    this.speechInit();
  },
  methods: {
    speakTtsSpeech() {
      this.speech.speak({ text: "公众号:霸道的程序猿" }).then(() => {
        console.log("读取成功");
      });
    },
    speechInit() {
      this.speech = new Speech();
      this.speech.setLanguage("zh-CN");
      this.speech.init().then(() => {});
