Hello! I have sucseeded!!!!! Finally I have written a module for cepstral that works. It doesn't support rate or pitch change, but who cares? also, if I need to do another module or want to change the dectalk configuration file into swift.conf do I need to modify something or can I just add the module swift with the addmodule command? /kristoffer ?Kristoffer Gustafsson Sols?ter M?nstadsv?gen 3 51453 M?nstad Telefon: 0325 42093 Mobil: 073-822 64 73 E-post: skeeter at allmail.net
