+Isn't there a GPL implementation of the GSM-FR codec? Why is Speex necessary?
+\layout Standard
+
+First of all, it's not clear whether or not GSM-FR is covered by a phillips
+ patent (see http://kbs.cs.tu-berlin.de/~jutta/toast.html).
+ Also, GSM-FR offers mediocre quality at a relatively high bit-rate, while
+ Speex can offer equivalent quality at almost half the bit-rate.
+ Last but not least, Speex offers a wide range of bit-rates and sampling
+ rates, while GSM-FR is limited to 8 kHz speech at 13 kbps.
