[Speex-dev] speex for windows mobile 2003

[doNz]

good day. i am an undergraduate student of electronics and
communications engineering and i would like to use SPEEX for my
thesis, which is to create a software that will record speech in
speex-compatible format for windows mobile 2003.(pocketpc devices) my
pocket pc has an inherent sound recorder but i am going to make a
sound recorder software specifically for speech files so that
recordings will take up less memory. i wanted to ask whether the mic
would need certain specs (since i am planning to just use the internal
mic of the device). also, is it possible to record the speech in speex
format and save it as .wav instead of .spx so it will still be
playable by the wav player of the device? would you recommend this?
thanks.
