I am developing a speech recognition application on Windows 7. I have a Windows 7 Home Premium with en-US as language. It ships with an English speech recognizer engine.
I would like to be able to switch between spoken languages on my application. After some research I've found that on Windows 7 Ultimate you can install 35 additional "language packs" via Windows Update and I'm thinking on buying Windows 7 Ultimate.
My question is:
Will installing any language pack from Windows Update also install additional speech recognition engines?
If not possible, how can I make my speech application to become automatically Spanish, French and German "fluent"?
