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_key
        self.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. This method exchanges your
    subscription key for an access token that is valid for ten minutes.

        voice = ElementTree.SubElement(xml_body, 'voice')

        voice.set('name', 'en-US-Guy24kRUS') # Short name for 'Microsoft Server Speech Text to Speech Voice (en-US, Guy24KRUS)'
        voice.text = self.tts
        body = ElementTree.tostring(xml_body)

        response = requests.post(constructed_url, headers=headers, data=body)
        '''
        If a success response is returned, then the binary audio is written
        to file in your working directory. It is prefaced by sample and
        includes the date.
        '''
        if response.status_code == 200:
            with open('sample-' + self.timestr + '.wav', 'wb') as audio:

        else:

            print("Reason: " + str(response.reason) + "\n")

    def get_voices_list(self):
        base_url = 'https://westus.tts.speech.microsoft.com/'
        path = 'cognitiveservices/voices/list'
