boosting responsiveness of accent pc

[Ralph W. Reid]

I have noticed the delay with the Accent PC (internal ISA card) on my
old Pentium 133 MHZ system running Slackware (currently version 10.0),
but have not found it to be objectionable.  This is the only speech
synthesizer I have run on Linux though, so perhaps I am simply used to
it???  I actually had to play around with the sample line of text you
provided (shortening it and adding additional text to it) to really
notice the delay--the delay does seem to get longer with longer lines
of text here as well.  HTH, and have a _great_ day.
