笔者花费半天时间搭建的网站：https://tool.szfx.top/tts
一、功能介绍
讯飞在线语音合成将文字转化为自然流畅的人声，提供100+发音人供您选择，支持多语种、多方言和中英混合，可灵活配置音频参数。广泛应用于新闻阅读、出行导航、智能硬件和通知播报等场景。
二、搭建教程
前期准备工作请参考文章：
官方提供的demo有python3、java、nodejs、js语言，这里以PHP调用为例构建一个API
index.php获取待转换文本和发音人，将参数传到python处理，将生成的cache.mp3文件重命名复制到时间线文件夹内。
<?php
header('Access-Control-Allow-Origin:*');
header('Content-type: application/json');
$text=isset($_GET['text'])? $_GET['text'] :null;
if(empty($text)){die("请传入文本参数");}
$vcn=isset($_GET['vcn'])? $_GET['vcn'] :null;
if(empty($vcn)){$vcn= "xiaoyan";}
$str = exec("python3 tts_ws.py $text $vcn");
$res = json_decode($str, true);//转换为数组
$response_msg = $res['message'];
if($response_msg == 'success') {$code = '200';}
else{$code = '202';}
$mp3Name = date("His", time()) . "_" . rand(1000, 9999) . '.mp3';
if (strstr($base64, ",")) {
$base64 = explode(',', $base64);
$base64 = $base64[1];
}
$pure_path = date("Ymd", time());
$path = "./data/" .$pure_path;
if (!is_dir($path)) { //判断目录是否存在 不存在就创建
mkdir($path, 0777, true);
}
$Mp3Src = $path . "/" . $mp3Name; //mp3音频文件名字
copy("./cache.mp3", $Mp3Src);
unlink("./cache.mp3");
$json_return = array(
"code" => $code,
"src" => $text,
"dst" => "https://api.szfx.top/xftts/data/".$pure_path. "/" . $mp3Name
);
echo json_encode($json_return, JSON_UNESCAPED_UNICODE);tts_ws.py文件内写入内容：

# 本demo测试时运行的环境为：Windows + Python3.7
# 本demo测试成功运行时所安装的第三方库及其版本如下：
# cffi==1.12.3
# gevent==1.4.0
# greenlet==0.4.15
# pycparser==2.19
# six==1.12.0
# websocket==0.2.1
# websocket-client==0.56.0
# 合成小语种需要传输小语种文本、使用小语种发音人vcn、tte=unicode以及修改文本编码方式
# 错误码链接：https://www.xfyun.cn/document/error-code （code返回错误码时必看）
