@Tamasg Either that, or a case of building the tools to build the tools to do the thing. The phoneme editor is an excellent, perfect start. But I suspect we're going to need tools to help us tune the klatt model any further. I don't think AI can get us much closer. But it might be able to help us build a tool to analyze the waveforms of the synths we like. We're probably going to also need a tool to help us tune the pitch/intonation table. If you look at the work of Dr. Susan Hertz, who built eloquence, she didn't start by building Eloquence. She built SSRS, a system for creating and editing text to speech rules. Then she didn't like it and wrote delta, a more powerful system. Delta was described as a hierarchical system for creating linguistic text to speech rules, where every rule could interact with rules on the levels above and below it. Based on her paper specifically on Eloquence, as well as her academic publication history, it looks like her team spent about 20 years writing tools, and then about five years writing eloquence.
