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.

Mark and Don are planning to sell each of their marble collections at a garage sale. If Don has 1 more than 3 times the number of marbles Mark has, how many does each boy have to sell if the total number of marbles is 113?
mariel Reply
Mark = x,. Don = 3x + 1 x + 3x + 1 = 113 4x = 112, x = 28 Mark = 28, Don = 85, 28 + 85 = 113

I think if critical temperature denote high temperature then a liquid stats boils that time the water stats to evaporate so some moles of h2o to up and due to high temp the bonding break they have low density so it can be a reason
