Thanks for the links, and I agree a proper man page or quickstart
guide would be super useful for end users! (and not just speech
synthesis researchers)
I checked out the YouTube videos, and I confess it was hard for me to
understand what Gnuspeech was saying... Is there a reason why it
doesn't sound nearly as natural as, say, Siri yet???
Siri uses a method called Unit Selection (AFAIK), which joins segments
of recorded speech. That is why the quality can be so good.
Gnuspeech uses articulatory synthesis, which uses a mathematical model
of the human vocal tract to synthesize the speech from scratch. It is
very difficult to adjust the many parameters. Also GnuspeechSA is a C++
port of the original TTS_Server (for NeXTSTEP), developed a long time
ago. It doesn't yet incorporate the research done in all these years.
Hopefully articulatory synthesis will reach the quality of unit
selection, but there is much work to do.
Regards,
Marcelo
