title: Phrase Rephraser
body: <p>I'm writing a bot and instead of phrasing user facing communication the same way, I want to implement a certain degree of change in the language, while still maintaining the original intent. To do this, instead of a standard dictionary key-value pairs, such as </p>
  
  <p><code>user_response ["GREET"] = "Hello, how are you?"</code> </p>
  
  <p>is currently replaced such:</p>
  
  <p><code>user_response ["GREET"] = ["Hello, how are you?", "What's up?", "Hi, all good today?"]</code></p>
  
  <p>and a random string is picked from the choices available.
  The problem is, it'll take much too long to do this manually, for all the strings in the system.</p>
  
  <p><strong>Question: Is there a way NLTK or other library can rephrase a given phrase?</strong>
  <em>There is a question from 2010 that is similar in intent, but didn't have much by way of responses or follow ups.</em></p>
