OK, guys,
I know, this has got nothing much to do with Window-Eyes itself to do. At 
least, not directly. Still, I thought it might interest some of you, just for 
the fun of it.

First of all, let me clearly state, I am no chess game player, and don't really 
have much knowledge about that game. Furthermore, I have no clue if the story 
here rendered, really is true. But the word is saying, that the guy who 
invented the game of chess, took it to the king locally. The king was quite 
excited about the game, and wanted to buy it from the inventor. He, on his 
part, replied the king, saying:

"Allright, I will sell it to you. For the first field on the board, I want ONE 
grain. For the second field, I want TWO grains. The ghird field, will cost you 
FOUR grains; the fourth has the price of EIGHT grains. For every field, I want 
a price, twice the price of the former. - If you can pay me all 64 fields of 
the board, I will let you have the game."

Not sure, which kind of grain they were doing - be Wheat, Barley, or whatever. 
Thing is, if the story goes right, the king had no chance to bring out that 
number of grains. Anyone knows, how many grains are in a pound of Wheat? Smile. 
I have no clue, but when realizing the number of grains in question, it must 
turn into a few ton. Quite a few, actually.

OK, so today, i decided to put the speech synths on my computer to a real 
"stress-test". I made a quick worksheet in MSExcel, and had it do all the 
mathematical calculations. The chart, you will find cited below.

Then, I ran down the columns, letting the speech synthesizer read out the 
numbers to me. My idea was, to see how far down in the chart, I could have the 
synth read the amount as a full number. And here, is the real interesting part 
of the project.

Some synths, ran down to the 50th field, and from field number 51, it would 
start to read out single digits. The worst synth, only managed the seven first 
fields, before she would start reading single digits. That was the CereVoice 
Kathrine. The most of the voices, Scansoft and NeoSpeech (Kate and Paul), 
managed full number reading, on nothing higher than field number 50. Best in 
test, was the AT&T voices (Crystal and Mike), along with the well-known 
Eloquence Reed - They managed even field number 61, before they had to give in, 
and start performing in single-digit mode.

Speaking of Eloquence, here is an intersting pint, which does stress the fact 
of differences between individual voices, even inside one and same synthesizer. 
Eloquence Reed and Sandy, both US voices,  both performed full number reading, 
down through field 61. But, switching to the German voice Max, from Eloquence, 
you could not get anything below field number 40, before he gave up his full 
number reading.

All the above testing, was performed with the screen reader set to "numbers = 
synthesizer". Changing this setting, and letting Window-Eyes take care of the 
number interpretation (Numbers = ON), None of the synths would perform 
full-numbers, below field 50.

OK, for the interest of the whole matter, the king would end up, paying 
something close to 18.5 quintillion grains. That is, 18.5 billion billions! No 
wonder he couldn't bring out that much, let alone do the math that high, 
without modern-day technology. - And, agreed, few of us, will ever have to deal 
with that high numbers, in our monthly budgetting. Smile. So, I do accept any 
objections, that this was an overkill stress-test on the synths. Yet, I found 
it interesting to let you all know of the results, since it does tell a bit 
about how differently made a synth can be. A synth that does not handle numbers 
anything higher than field 7 in the chart below - which in daily life would 
mean anything higher than one-hundred-thousands, we might conclude that the 
manufacturer has not bothered to do too much work on. The CereVoice Kathrine, 
does have a nice human touch to it, but it holds several errors in 
pronunciation - and like this test showed, even cannot handle numbers in full, 
once they exceed 100 thousand. Still, it is not among the cheapest on the 
market. The SAPI and NeoSpeech voices here tested, did perform well all through 
the fifty first fields, which by far will exceed the normal wages of any 
emplyee. :) They are not too expensive, have a varying grade of human touch to 
their voices (all depending on taste and actual voice), and are fairly priced. 
But even with the specially dedicated Eloquence voices in Window-Eyes, which 
are quite well performing in human sounding (at least to some degree), the test 
showed differences of quite a stretch. The US voices, dealt with numbers even 
through field 60, whilst the German voice, had no chance from field 41 and 
onward.

Well enough, numbers are not that big a deal, and this stress-test might seem 
silly to most users. But it does show some of the differences, and maybe gives 
some fun for any of you, who choose to fool with the below cited chart. Enjoy!
