An overview of the testing methods and the results of the tests.

Identity checking results

For testing purposes, we had five sounds that the system would test–three vowel sounds, and two words. Each member of the group tested a each sound 5 times. The possibleresults for a test are as follows: match (M), meaning the system identified the speaker correctly; incorrect match (IM), meaning thesystem identified the speaker incorrectly; or no match (NM) meaning the speaker did not find the correct speaker in thedatabase.

Identity checking test results
“Ah” “Oh” “Ay” “Avocado” “Diablo”
Speaker M IM NM M IM NM M IM NM M IM NM M IM NM
Damen Hattori 4 1 0 4 1 0 3 2 0 2 3 0 4 1 0
Josh Long 3 2 0 4 1 0 2 3 0 5 0 0 3 2 0
Matt McDonell 1 4 0 5 0 0 3 1 1 4 1 0 5 0 0
Chris Pasich 4 1 0 2 1 2 2 1 2 3 1 1 2 3 0
Overall 12 8 0 15 3 2 10 7 3 14 5 1 14 6 0
Overall PercentCorrect 60% 75% 50% 70% 70%

Overall, the system identified speakers correctly 67% of the time. On an individual basis, Matt McDonellwas recognized most often (72%), Damen Hattori and Josh Long were recognized correctly equally as often (68%) and Chris Pasich wasrecognized correctly with the least frequency (60%). Overall, however, all speakers were identified at a fairly good rate, giventhe complexity of the system.

Vowel checking results

In addition to testing whether a speaker was identified correctly, we also tested to see if the system correctlyidentified vowel sounds. The vowel sounds were either found or not found, and were never incorrectly identified. The overall resultsare listed in the Vowel Checking Results below.

Vowel checking test results
“Ah” “Oh” “Ay” “Avocado” “Diablo”
Vowel Found 20 18 17 71 49
Vowel Not Found 0 2 3 9 11
% Vowels Found 100% 90% 85% 88.75% 81.7%

Overall, the system correctly identified 87.5% of all vowels correctly, an extremely high rate for a vowelchecking system. As the word became more complicated, the vowels were not found as frequently. This is a result of the addedsyllables and the emphasis on the consonants in the words.

Results overview

Overall, our results were acceptable for a system of this much complexity. A system that correctly identifiesthe speaker with 67% accuracy is not good for security purposes, but with fine tuning and more time, the accuracy could easilyincrease. One of the more important results from our testing is that, as the complexity of a spoken word increased, the accuracy ofthe system also slightly increased. There is much more room for error with longer words than with single-syllable vowels, and thisis reflected in the overall increase in accuracy.

sure. what is your question?

20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?
ninjadapaul
hmm
Abhi
is it a question of log

The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world

Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
