Access-Control-Allow-Origin missing, Microsoft Speech-to-Text JavaScript API
<p>I am trying to use Microsoft Speech-to-Text JavaScript API. It does not work. I get the following:</p>

<blockquote>
  <p>Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at <a href="https://api.cognitive.microsoft.com/sts/v1.0/issueToken" rel="nofollow noreferrer">https://api.cognitive.microsoft.com/sts/v1.0/issueToken</a>. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).</p>
</blockquote>

<p>Any ideas?</p>
