Re: effects of replay on intelligibility
I'd be very careful about applying results from synthetic speech to anything
else. As a long time user of synthetic speech I can tell you that systems such
as lpc produce problems specific to the voice chip being used and even for long
time users it is sometimes necessary to "replay" what has been heard.
