The clarity and accuracy of the speech is quite good. I am interested in the process of creating a new language using espeak. Where can I get more detail on that? I think there is a bug in the espeak program when reading long text files. To me it is no problem as I am using speech-dispatcher which sends smaller chunks of text at a time, but others might be using the file feature. The program segfaults after a time. Thanks again for a great program. Regards, Willem On Thu, 13 Apr 2006, Jonathan Duddington wrote: > I've just found this mailing list from a comment on the > espeak.sourceforge.net forum.
