Re: Free TTS engines

If a stratified random sample of individuals with various levels of effectiveness with a screen reader were compiled, I'm sure you'll find the 75% is pretty average. the higher speeds are probably used by some for passive reading of insignificant material where detail is of the least of importance. I'm more of a detail freak in lots of my daily routines and therefore choose to vary the speed here and there in order that I don't miss anything. Of course, mileage may vary depending on an immense amount of variables beginning with the type of screen reader and how it measures reading speed.

I tend to use 75% for normal use, and then 65 or so for relaxed reading ...
sometimes 80 or 85 if I'm just browsing ... don't know how slow or fast this
is compared to others.

Take care,
Sina

I have mine on 65 with punctuation set to all, which a lot of people don't
like, but since I listen to a lot of computer science mail in which
punctuation is significant, it is what I have gotten used to.  Still it's
kind of a pain to listen to "we apostrophy l l" and other contractions even
if it is at high speed.  I'm impressed that you have it on 64 with english
not being your native language.

I am using Jaws with Eloquence, and In the menu
Options/Basics/Voices/Global  adjustment, I have set the rate to 64%.

This is because english is not my native language, but maybe other users use
a higher rate.

People talk quite a bit about how fast they have the TTS engines going.

Would anyone mind posting a couple soundfiles of your screenreader
reading computer code at your "usual" pace? I'm curious how fast folks
typically have it going. I suspect that, in our pilot studies, we have
the TTS engine going way slower than you folks do.

Natural Voices, VoiceText, Loquento and other modern synthesizers are
concatenative, requiring speech segments to be looked up, best match
found,
then interpolated in order to be modeled on a particular human voice and
sound natural.  To adjust their speed, you have to do some more
interpolation and matching, as you do for time-scale modification of
natural
speech, and this begins to get rough and less intelligible as you go to
twice normal speed or faster.

The older synthesizers, such as DecTalk, Eloquence and the SSI263 speech
chip used by Artic, Braille 'n Speak, Votrax, Accent, etc. are formant
synthesizers.  They work on a vocal tract model, and the parameters can
be
varied systematically to alter the speed without creating quite as much
distortion or losing consonants.  Of course they don't sound as natural,
but
this is mostly a hindrance to people who don't spend days and days
listening
to them, for whom speed is more valuable than naturalness.  The other
advantage of the vocal-tract synthesizers is that they don't require as
much
data to be handled, so they work better for echoing individual keystrokes than the ponderous concatenative synthesizers. Even on modern computers,
these speed and responsiveness issues are important.
