要在Vue 3中实现语音交互的前端页面,你可以使用Web Speech API。以下是一个简单的例子,展示了如何在Vue 3组件中集成语音识别(speech recognition)和语音合成(speech synthesis)功能。
首先,确保你的项目中安装了vue3。
npm install vue@next
然后,创建一个Vue组件:
<template>
<div>
<button @click="startRecognition">开始录音</button>
<button @click="synthesizeText">开始播放</button>
<textarea v-model="text" placeholder="输入或编辑文本"></textarea>
</div>
</template>
<script setup>
import { ref } from 'vue';
const SpeechRecognition = window.SpeechRecognition || window.webkitSpeechRecognition;
const SpeechSynthesis = window.SpeechSynthesis || window.webkitSpeechSynthesis;
const recognition = new SpeechRecognition();
const text = ref('');
function startRecognition() {
recognition.start();
recognition.onresult = (event) => {
const result = event.results[0][0].transcript;
text.value = result;
};
}
function synthesizeText() {
const msg = new SpeechSynthesisMessage(text.value);
SpeechSynthesis.speak(msg);
}
class SpeechSynthesisMessage {
constructor(text) {
this.text = text;
this.lang = 'zh-CN';
this.voice = SpeechSynthesis.getVoices().find(v => v.lang === this.lang);
this.rate = 1;
this.pitch = 1;
}
get text() {
return this._text;
}
set text(value) {
this._text = value;
}
get lang() {
return this._lang;
}
set lang(value) {
this._lang = value;
}
get voice() {
return this._voice;
}
set voice(value) {
this._voice = value;
}
get rate() {
return this._rate;
}
set rate(value) {
this._rate = value;
}
get pitch() {
return this._pitch;
}
set pitch(value) {
this._pitch = value;
}
}
</script>
这个例子提供了基本的语音识别和语音合成功能。点击"开始录音"按钮可以启动语音识别,并将识别的文本显示在文本域中。点击"开始播放"按钮可以使用文本域的文本进行语音合成。
请确保在一个支持Web Speech API的浏览器中运行此代码。
