Well check the Makefile for espeak. With lots of software these days, especially if it uses the autoconf, the Makefile will check if you have various libraries and use them if it finds them. I don't know if espeak requires JACK, but if not, there should be a way to exclude it by modifying the Makefile generated by autoconf. If it doesn't use autoconf then check the static Makefile and look for the reference to JACK. -- Doug
