title: Microsoft Cognitive speech services - Speech to text batch transcription permission error
body: <p>Hello!<br>
  I am trying to use MS cognitive services for speech to text transcription. I need to run a sample first before I build it into my production app though. So I am trying out this: <a href="https://github.com/Azure-Samples/cognitive-services-speech-sdk/tree/master/samples/batch/csharp" rel="nofollow noreferrer">Git sample</a></p>
  
  <p>This sample basically just asks you to fill in the host name, subscription key and the Azure blob URL. I have done all of that and I am able to get the JWT token and read what files I have uploaded so far(0 actually). 
  Just that when I try to upload a file for transcription it gives me this in response: </p>
  
  <pre><code>InnerException  {"Only \"Standard\" subscriptions for the region of the called service are valid."} System.Exception {BatchClient.FailedHttpClientRequestException}
  </code></pre>
  
  <p>So, are trial users not allowed to use the service?<br>
  Is there a API within MS cognitive services which supports trial users so that we can try out the service before buying?<br>
  I have tried to run through their docs but it is not clear what all options I might have in this context.<br>
  Any help will be appreciated.<br>
  Thanks in Advance!</p>
