1、申请账户：

https://azure.microsoft.com/zh-cn/free/

这里有个视频教程，根据此完成申请流程：
https://www.bilibili.com/video/BV15a4y1W7re?vd_source=bf07f28d37849885d215dc3aea189eba
申请完成后，就可以到这里申请资源：
https://portal.azure.com/#home

点击资源组，里面就有部署好的服务了


点击这里，可以获取 subscription_key，另外还有个就是位置service_region (上图就是east asia)，这两个后面会用到。

2、调用服务

在完成微软azure服务账号申请后，就可以进行调用了。代码：

'''
After you've set your subscription key, run this application from your working
directory with this command: python TTSSample.py
'''
import os, requests, time
from xml.etree import ElementTree# This code is required for Python 2.7
try: input = raw_input
except NameError: pass'''
If you prefer, you can hardcode your subscription key as a string and remove
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"
'''if 'SPEECH_SERVICE_KEY' in os.environ:subscription_key = os.environ['SPEECH_SERVICE_KEY']
else:print('Environment variable for your subscription key is not set.')exit()class TextToSpeech(object):def __init__(self, subscription_key):self.subscription_key = subscription_keyself.tts = input("What would you like to convert to speech: ")self.timestr = time.strftime("%Y%m%d-%H%M")self.access_token = None'''The TTS endpoint requires an access token.
