Hi

I am running asp.net ajax (vs 2008)
I have the following webservice listed below.
However, i have no idea how to call this from javascript.
Originally, before i started using the BeginXXX and EndXXX as per
http://msdn2.microsoft.com/en-us/library/aa480516.aspx
I could easily call the webmethod via in this case
"WebService_speech.GenerateSpeechDataForText"
but now im not sure how to call it.
Any ideas?
Thx for any help here...greatly appreciated
