I agree with Jon I think - the range of useful values is very very slow to
very very fast. I think for accessibility it is a clear P1 that it can go
slow enough, whatever that is, and I think it is probably an important P2
that it can go fast enough. I find, using the speech built into Macintosh,
that it is slower than I would like for real efficiency, but it does allow me
access to the content (and I am not accustomed to using it yet - I am aware
that for an expert user it would be like having a 300 baud telephone line -
posssible, but very unpleasant).

  The documentation for SAPI is available in HTML, but it is a part of the 
  Software Development Kit (SDK)[1] as a local resource.  There does not 
  appear to be a similar resource for SAPI on the Web.
  
  The requirement should be to allow the user to user to set parameters 
  anywhere with in the range of the synthesizer and that the user agent 
  should provide information on the ranges available.
