python文本转语音(微软xiaoxiao语音)

前言

1. 准备工作

话不多说，马上开始，首先登录 Azure portal,

1.1 选择 “认知服务”，添加一个新的 Speech 订阅，名称随便起

1.2 位置选择东南亚

1.3 定价层选择 F0

因为xiaoxiao的语音属于神经网络语音 所以选择地区时要选择 神经网络可用区域 才能使用微软xiaoxiao语音

F0是免费版，每月有一定的免费额度可以使用

1.3 Speech 部署完成后

点击左侧列表中的 “所有资源”连接，进入资源管理面板

1.4 选择资源，查看密钥

在资源面板点击刚才创建好的 MySpeechService，进入详情后点击 “密钥和终结点”，可以看到已经生成好的密钥，等一下调用 Speech 服务的时候需要用到。

After you've set your subscription key, run this application from your working
directory with this command: python TTSSample.py

the provided conditional statement. However, we do recommend using environment
variables to secure your subscription keys. The environment variable is
set to SPEECH_SERVICE_KEY in our sample.
For example:
subscription_key = "Your-Key-Goes-Here"
