title: Using IBM Watson Text-to-Speech with Postman?
body: <p>How do I use IBM Watson Text-to-Speech with Postman? To test I just want to get the list of voices. I set up a <code>GET</code> request with the url</p>
  
  <pre><code>https://stream.watsonplatform.net/text-to-speech/api/v1/voices
  </code></pre>
  
  <p>Under <code>Headers</code> I set my <code>username</code> and <code>password</code>.

  <p>Watson responded with:</p>
  
  <pre><code>{
    "code": 401,
    "error": "Not Authorized",
    "description": "No credentials supplied."
  }
  </code></pre>
  
  <p>Where do the username and password go in Postman?</p>
