For the ultimate in voce compression however, there
are free GSM
compression/decompresison tools. In debian the gsm-utils pachage seems
to the the thing you need, no doubt will pull in all the various libgsm*
packages too. I haven't used it, but if you can get it to do what you
want you waon't get better voce compression.
My experience of European mobile phones which use GSM voice compression is that sometimes
the speech is uninteligable. Of course the GSM compression may be responsible or it may
be a combination of the compression algorithm and errors introdcued by the network.
Before choosing GSM I would need to conduct tests to see if the algorithm performs well
when separated from the phone network.
The debian gsm-utils package seems to be all about phone books and SMS rather than speech
compression.
What little I have seen of speex, it seems to work well.
