Vue语音播报功能可以通过使用浏览器提供的Web Speech API来实现。这个API允许你的应用程序通过浏览器朗读文本,不用安装任何包和插件,直接调用。以下是一个简单的介绍,演示如何在Vue中使用语音提示功能:
一、JS版本
<template><el-button type="success" @click="playVoice">Web Speech API</el-button>
</template>
<script>
const synth = window.speechSynthesis // 启用文本
const msg = new SpeechSynthesisUtterance()
export default {data() {return {}},methods: {playVoice() {this.handleSpeak('测试111111111') // 传入需要播放的文字},// 语音播报的函数handleSpeak(text) {msg.text = text // 内容msg.lang = 'zh-CN' // 使用的语言:中文msg.volume = 1 // 声音音量:1msg.rate = 1 // 语速:1msg.pitch = 1 // 音高:1synth.speak(msg) // 播放},// 语音停止handleStop(e) {msg.text = emsg.lang = 'zh-CN'synth.cancel(msg) // 取消该次语音播放}}
}
</script>
二、TS版本
运用TS封装形式来实现语音播报功能。
创建一个VoiceAnnouncements.ts的文件,然后在应用的Vue页面进行引入该ts文件并使用。
class VoiceAnnouncements {public synth = window.speechSynthesis // 启用文本public msg: any = new SpeechSynthesisUtterance()public language: string = 'zh-CN' // 使用的语言:中文public volume: number = 1 // 音量public speed: number = 1 // 语速public pitch: number = 1 // 音高// 开始语音提示startVoiceFunction = (content: String) => {this.msg.text = contentthis.msg.language = this.language this.msg.volume = this.volume this.msg.speed = this.speedthis.msg.pitch = this.pitchthis.synth.speak(this.msg) }// 停止语音提示stopVoiceFunction = (content: any) => {this.msg.text = contentthis.msg. language = this. languagethis.synth.cancel(this.msg) }}//传出实例,保证整个系统只存在单例的Voice
const VoiceAnnouncementsInstance = new VoiceAnnouncements()export default VoiceAnnouncementsInstance
