Ok, I'll have to pass that on, since the way it's hosted at the moment, you
won't see anything apart from the standard HTML tags, linking to external
script source files, and, again, the one real one, with the actual
implementation script in it is hidden by a PHP session variable check.
Firstly, the two sort of script libraries I am making use of are, JQuery
(simpler/clean access point for a version/implementation of DHTML):
http://jquery.org/
and, SoundManager, which implements the embedded flash object to handle the
sound playback etc.:
http://www.schillmania.com/content/projects/soundmanager2/
Then, there's around 360 lines of javascript, handling everything from
initialising the objects containing/wrapped around the sounds, attaching event
handler functions to the objects on the page - using basic javascript syntax,
but approaching it a bit other than normal, along the lines of the JQuery
methods/approach, etc., and if you want, I can try post some of that again,
etc., since the only real change have made this time around is to in fact
handle a sort of queueing of sound playback, using an array to store the
identifiers of the sound objects to be played, one after the other, and all I
did extra there was add a bit of a check to the onFinish event of the sound
objects to then check if another sound in fact needs to be played, and if so,
to then play it, etc.
My theory is that javascript, PHP and C# are relatively similar in terms of
basic syntax, but they all have each of their own peculiarities, etc., and this
then gets a slight add-on from using JQuery (unless I'm just not used to really
taking javascript to this full level or something), and the only other 'funny'
thing about javascript is that along the lines of defining a variable inside a
method/function in other languages, and not having it available to other parts
of the whole overall structure, variables generally defined within a script
block <script...></script> are to a certain extent limited to being seen
therein, but the DOM (document object model), with the window object sort of at
the top of it, can be seen/accessed from all around, etc. - and this is all
just my sort of general version of an explanation of my version of an
understanding of javascript, etc.
Stay well

This is very interesting.
While I don't have a lot of knowledge or experience with HTML and the various
scripting I am looking forward to looking at the source in detail when I get
some time.
Very clever.

The voice is scansoft/realspeak daniel, but I did output/render the clips
at quite a fast speaking rate to partly try drop their file size/running time,
and I also dropped them to 24kbps (kilobits per second) to make all 10 of them
that might get used amount to a total of 14kb, and the idea with the embedded
flash object preloading them is that they get sort of cached at load time,
instead of needing to be reloaded/refreshed each time they need to get played,
etc., and it seems to me like they do each sort of play a bit quicker from
their 2nd time onwards, but, yes, it's not 100% real time as such either way.
I was also testing/trying out catching actual keystrokes via the
document/webpage itsself for navigation etc., but you would then need to turn
off things like jaws since it's catching of the navigational keystrokes for
it's virtual buffer block the javascript DOM from noticing them as
such...<smile>

Ah!
That works more like it.
Cool. I have a little trouble with the voice, a little difficult to hear
particularly over Jaws but without Jaws it would probably be better.
I am guessing that with dial-up the delay would be unacceptable but here
it isn't much.
Very clever.

You will at this stage need to tab onto the buttons to in fact focus
windows on them as such since just normally moving around in the screen reader
virtual viewer doesn't really focus on them as far as javascript is concerned.
If you are using jaws, and you route jaws to virtual cursor, it should
also speak since I have also attached the playing of the relevant sound clips
to the mouse cursor hover event, but anyway.
Thanks for trying it out...<smile>

Hi Jacob,
When I press space on a location I do hear "knot" but moving around I
get nothing else. If I space on a button I have already checked I hear sorry
but I don't hear the state of the button when landing on it. I take it I should?
The delay isn't bad, an interesting approach.
Cool.
Dale Leavens.

There should now be a form of narration in that when you focus on
one of the buttons, or even hover a mouse cursor over it, you should hear the
narrative sound clips, etc.
Issue is still something to do with preload timeframes etc., since
even though the sound clips are pretty small/tiny, it still pauses a bit, but
anyway...
