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”
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.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
