Or perhaps the answer is more like "maybe". ;)  I'm still holding my breath for 
pocketsphinx...   The page does say it works with StrongARM, which if I'm 
reading wikipedia correctly was just 206MHz.

This is a nice idea to offload processing to another box and spit back the 
results. One big problem I have with the Tellme approach is that it isn't free 
as it's using some service provider. Blah for me there. That said, there's no 
reason the ideas behind it couldn't be implemented freely.

I've done speech recognition with sphinx and asterisk. It doesn't work too 
great--the main problem being that GSM is a pretty low quality sample for it to 
work with. You know how you can never understand anyone talking on a cell 
phone? ;)  Well, sphinx can't understand it too well either. But pocketsphinx 
(which I haven't tried) lists on their page "telephone-bandwidth models"--this 
looks promising.

For SIP, you need some sort of net connection, of course, and I think we can 
assume that that is coming. Then you can use alaw/ulaw instead of GSM and that 
will help recognition quite a bit...
