启动
python ttsServer.py
测试
# 访问该地址 可查看window的语音包 若无货缺失 可使用高版本window10 或安装语音包
# 安装自行百度
http://localhost:5000/ttsLang
# 若存在，结果可能如下
{
"data": [
{
"id": "HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Speech\\Voices\\Tokens\\TTS_MS_ZH-CN_HUIHUI_11.0",
"index": 0,
"name": "Microsoft Huihui Desktop - Chinese (Simplified)"
},
{
"id": "HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Speech\\Voices\\Tokens\\TTS_MS_EN-US_ZIRA_11.0",
"index": 1,
"name": "Microsoft Zira Desktop - English (United States)"
}
],
"msg": "成功",
"status": 200
}
然后，可去调用 接口 ：http://localhost:5000/tts 测试啦 ，请求参数自行观看代码
