最终思路思路就是vue前端向后台发送需要播放的语音信息(文字),然后后台返回语音流数据,通过URL.createObjectURL(data)这个API生成一个URL，然后给audio标签附上url，网页进行语音播放，在网页播放语音就可以避免用户的本地语音库的安装。在Vue项目中用Audio实现语音的播放（基础版）1.axios 拦截处理// respone拦截器service.interceptors.response.use( response => {.
主要参考了这两篇博客
https://blog.csdn.net/zhang45362613/article/details/112538607
这一篇的采集方案，采集到语音数据后上传服务器
https://blog.csdn.net/qq422243639/article/details/79238983
这一篇的自动播放方案，websocket接收到数据后，立即播放
其实这一篇涵盖了采集的方案，但是代码有许多过时的语句，也就没有采用
前端代码：
其中有很多需要调用的js文件，可以直接去git这个项目，里
let minSampleRate = 22050
self.onmessage = function(e) {
transcode.transToAudioData(e.data)
var..
在项目中需要用到将景点文字合成语音，通过语音方式向用户介绍景点信息，需要用到文字转语音的在线合成解决方案。通过对各种文字转语音合成方案与效果比较，觉得讯飞的效果最好，语音拟人效果、文章断词都非常不错，并且有一年10万次的免费使用量，因此对比后决定使用讯的在线语音合成解决方案。由于这信主题网上教程非常少，只找到了一个没提供完整源代码的参考案例，结合官网资料，搞定的完整解决方案和效果图如下:
