Hi Chip! As I understand it, a nice channel vocoder would be OK for you. So you could use a LADSPA plugin, I blieve there is a vocoder, or youcould use csound, which also relates well to JACK and there is a vocoder udo (kind of more complex preprogrammed workmodule. I belive you could make mbrola sing. But with synthesizers like mbrola and festival, the problem is the terms of use for the voices you get. But for festival there should be at least two or three free English ones. Festival is highly programmable. You can ask it to use an external soundplayer, so youcan use something, that works with JACK. But it's not very realtime. I tried and results were mixed. Good thing about Festival: It's based upon a lot of scheme configuration files, controlling every aspect of the software. So you can manipulate it to your liking. Bad thing: You need to understand what to do, where to do it and how to properly write the scheming language. :-( Kindly yours Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de
