How much swap space do you have? Flite requires a *huge* amount of memory to build successfully. If you have some free hard drive space, I'd set up a large temporary swap file. Seriously, I'd suggest at least 1GB of swap. The reason it requires such a tremendous amount of memory to build is that the voice is entirely in C, and is like 20MB of source code. I don't recall the exact numbers, but I was surprised that something which requires such a huge amount of memory to build can run in a fairly small amount once built. Another option is a pre-built binary. Somebody once put together a binary package for Slackware of Flite that used the 16-bit voice which improves fidelity somewhat. I can't remember who it was, though. Maybe, it's still in the list archive somewhere. Flite is an OK synthesizer, but somewhat flat and lifeless sounding. It also has some strange pronunciation rules. For example, it consistently pronounces Linux as if the x at the end weren't there. It also tries to process abbreviations which all the modern synthesizers seem to do. It drives me nuts when they decide to treat part of an email address as an abbreviation.
