@jscholes @cachondo @Tamasg @ZBennoui So some of the issues you're identifying have to do with the espeak phonemizer, and the way phonemes are tuned. We have a lot of work to do there, too. But I feel like if we can get the sound of the voice correct, that will be a lot easier. For example, compare speech player and eloquence saying "eeeeeeeeee". Side by side, it's clear something is still not right with speech player. It needs to be...rounder and brighter? And...those are not useful terms because I'm still struggling to define exactly what I mean by them haha.
