Hi Isaac,

You are correct.  SA To Go downloads the minimum it needs to start working,
then carries on downloading in the background while you are using it.  When
you shut it down, everything is deleted.

All the best

Hello Si

I don't think that converting to speech on the server is practical - not
beyond a research project; the computation penalty would be too great when
many users would use the site.  If some of the text is pre converted the
storage requirements would be enormous for each page.

On your second point, regardless of how clever the web engineering is,
whatever you do, connection is always unpredictable and many time slow due
to bottlenecks between the server and the client - on a home connection
anyway.

I suspect (but don't know) that the SA to Go converts to speech using a
local program downloaded to your computer which is I think a better
approach.

Regards
Isaac

Hi Guys,
So as far as I'm aware WebAnywhere is for use on machines - mainly public
machines when there is no access to USB or CD for security purpose; and for
situations such as kiosks etc. It works by generating Speech for an http
session on the server side and encoding it as MP3 - then sends it to the
client via JavaScript calls coded into the page by a proxy. It's some pretty
cool Web Engineering especially because the latency is not noticeable as
their encode and send algorithms are leading edge.

Cheers
Si.
