I personally am not an eloquence fan anyway, mostly because it can't do a half decent British English accent. orphius human sounding voices I've always found a great compromise between speed and understandability AND THERE ARE NO ORPHIUS CRASH STRINGS AS FAR AS i KNOW, though these days with the improvements to vocalizer, (and a few orphius CONFLICTS in later version of supernova), I've largely switched to using realspeak daniel full time, (AND i'VE YET TO FIND A VOCALIZER CRASH STRING EITHER).
It actually seems that the general voicing technology has very much improved. I remember when the realspeak voices had such a major lag in response time they were nearly unusable, at least at the speed I prefer them, thankfully that has very much changed, at least as far as supernova (and indeed all Ios devices), are concerned..
Listening to the new voice for Siri on Ios, I do wonder if we'll get to a point where the rythms and word pause issue that have always been a stark line between human and synth voices (even the better synths), will no longer be an issue.
I do look forward to that time, sinse that will be the point where there will be no distinguishable difference between a bad human narrator (ie one who does not do character voices etc), and a synth.
It's not happened yet, well not satisfactorally enough for me at least, but I don't think we're that far off.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
