Many of the MP3 players out there have recording capabilities.  Last I 
checked, all the iPods except the iPod mini actually have record 
capabilities, and you can get a mic from 3rd parties that works with it.

I think the others likely have recording capabilities as well.   As far 
as whether they can record and playback speex, it depends on the 
DSP/microcontroller the device uses, it's capabilities, and how much 
work they're willing to do to port speex to their device.  In the case 
of these music players, if it's got the power to do encode MP3 or AAC, 
it surely can encode speex.

But, if you don't want to advocate speex to those companies, you can 
surely advocate to whatever company makes the thing you have (i'm not 
sure why you haven't shared that information here yet).
