Helping Meghan Speak (Avalon & SAPI)

I saw this post https://www.longhornblogs.com/robert/archive/2005/11/11/15246.aspx and just had to help out. Here is something I quickly threw together.  It uses SAPI 5.1 & Avalon.  To use this, you need to add a reference to the SAPI com component (Install the SAPI SDK if you don't already have it).  Download the project and code.  Good luck Meghan!!

  The SAPI stuff looks cool.
  
  But this code sample actually serves to show how much typing is required to build a simple UI in Avalon and C#. Please tell me you used a graphical lay-out tool and didn't hand-code all that XML? And those 10 "using ..." lines must have been added by some wizard, right?
  
  I'm going to go buy stock in companies that make ergonomic keyboards and voice recognition software.

  Matt,
  
  I wanted to take a second and thank you for putting this together for Meghan. She saw it this evening and flipped out at how cool it was. I'm currently setting the Speech and Avalon SDKs up on my VPC, so that I can add some UI for adding new phrases.
  
  It was really awesome of you to put this together for her, and she's very grateful. I had no idea working with the Speech SDK was so easy!
  
  Thanks again, Matt!
  
  -Robert & Meghan

  Ohhhhh.. that pink........... :(
  
  Just wait until WPF is released, all of the beautiful application UIs we'll see...
  
  (I'm getting flashbacks of 1997 home pages with blinking text, dizzying background patterns, marquees, background sounds...)
  
  Sorry, couldn't resist :)

  Actually, pink is Meghan's favorite color (he probably gathered from her website). She got super excited when she saw it was pink.
  
  Hey PatriotB... the next time you feel the urge to open your mouth... maybe you should try resisting harder.
