I had pretty good results recording from a standard headset, on a basic sound card at 44Khz mono. After recording a set of words/phrases I used audacity to chop them up, trim off excess silence and then optimise/standardise the levels. As I was feeling particularly fussy I also filtered out obvious clicks and any background noise. Final step was to convert the files to gsm format using sox (make sure you adjust the sample rate to 8Khz). I may have missed something or got the syntax wrong as it's been a while since I did this, but I think the syntax was: sox sample.wav -r 8000 sample.gsm resample I think the extra processing is worth it as the improvement in sound quality is striking. It's especially obvious if you are recording elements that will be concatenated to form phrases (e.g. numbers).
