title: Complete requested API address list for Microsoft Azure Cognitive Service TTS API
body: <p>I am testing Azure TTS service and it is working well on my dev PC.</p>
  <p>Now, I am test on a windows server in a secure data center.</p>
  <p>However, it may not work because of company firewall system which blocks both inbound/outbound traffic.</p>
  <p>So, I need complete API address list to open firewall.</p>
  <p>I am using C# and Azure Cognitive Service Nuget package.
  I initialize SDK using “SpeechConfig.FromSubscription(key, region)”.</p>
