Re: ViaVoice outloud on 64bit Ubuntu

["Tim Cross" <tcross@xxxxxxxxxxx>]

Hi Raman,

I updated to the latest version from googlecode, did a make clean and make
within linux-outloud directory. New version still has the artifacts and no
longer does character echoing. 

I tried your suggestion of increasing the usleep call and tested values from 1
to 40 with no observable impact on the speech artifacts. If anythhing, the
problem may have gotten slightly worse with higher values, though it is hard to
tell. I also tested with usleep completely commented out. None of these
permutations appear to have any significant impact. 

While typing this message, I also notice that in addition to the loss of
character echo, many short words also do not get echoed. It would seem that any
word of 3 or less characters is not echoed and some words of 4 characters also
fail to be echoed. All words of more than 4 letters appear to be echoed. 

I also notice issues when moving around text. For example, the line above which
only has the word 'tell.' does not get spoken when you move up over that line,
either with C-p or the up arrow. 

I did notice quite a few compiler warnings in the most recent code which were
not there in the last version. Initially, I guessed these were just a result of
your testing/development work and ignored them. However, a couple did look a
bit suspicious. I've copied them below.
