eSpeak's home page is at http://espeak.sourceforge.net/ On this page, there are links to both a forum and an email list. You can send your inquiry to whichever one you feel the most comfortable using. Jonathan Duddington, the developer of eSpeak, also hangs out on this and other screen reader/TTS related lists, so he is actually likely to see your message here. Do feel free to post in the eSpeak list and/or forum as well, however. ~Kyle
