Re: eSpeak - Introduction

[Willem van der Walt <wvdwalt@csir.co.za>]

Hi Jonathan
Thanks for a much needed useful free software synthesizer.
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
