[Blindmath] Using the vOICe learning edition

[Amanda Lacy]

At seeingwithsound.com go to the link that says site map. On that page there 
is a link called "accessible graphing calculator." That page will tell you 
how to use it. However, I recommend a couple of things before hitting F8 to 
start the graphing calculator. First, hit alt control f3. This will slow the 
time it takes to sound the graph from 1 to 4 seconds, making it much more 
understandable. Second, I always use stereo earphones or headphones when 
looking at these graphs of course being sure the left earpiece is in my left 
ear. When you first press F8, you will hear a continuous tone from left to 
right (the x axis), a click in the center (the y axis), and what sounds like 
a siren going from left to right (the default sine function). You should 
also land in the function edit box. An example: If you delete the selected 
function and type y = x, you should still hear the axes as described 
earlier, but instead of that siren sine curve you should hear a steadily 
rising tone going from left to right in the speakers. If you instead type 
the constant function y = 1, you should hear the y axis along with two 
constant tones - the x axis and a tone that is just a little bit higher in 
pitch than the x axis.

I hope this helps.
