# EVALUATION
# - of the tts
# - of the method: consistency? coherency / interpretability of 'best' voice across different features; alt. ability to recover good & problematic features from a combined method if that is chosen as the best? 
# - how similar are the results across different sentences? are any voices consistently good or bad; if multiple are good, are they good in the same way or good in different ways; do humans agree.
#  >> bc hey THAT could at least be an argument for the method, u might have to take time for human judgement once but then you can keep re using it free for new voices. or to select among alternative generations given you might know a context and know what you're going for in that context. etc.
