Even if SAPI were built into the operating system for your Pocket PC, that
does NOT mean that you can to speech-to-text; you need a suitable plug-in
for SAPI that actually does that. All SAPI is is an API; it doesn't do
ANYTHING itself.
Windows CE 5.0 does have SAPI AVAILABLE, but it doesn't sound like you
understand what Windows CE is. It is NOT *an* operating system. It's a set
of components that can be assembled in an almost infinite number of ways to
provide an operating system for a custom device. The fact that a device
builder CAN build SAPI into his Windows CE 5.0 operating system does not
mean that all OEMs do that; in fact, almost no one does that. So, you'll
almost certainly have to purchase or write a recognition engine, as Casey
did in the article that you linked to...
