(1) Input: Speech of size , sampling frequency , duration second |
(2) Preprocess the signal using preprocessing algorithms described in Section 7.1 |
(3) Obtain Dw1, Dw2, Dw3, Dw4, Dw5, Dw6 using the DWT |
based segmentation described in Section 4 or obtain SW1, SW2, SW3, SW4, SW5, SW6 using the SOM weight |
vector extraction algorithm described in Section 5 |
(4) Find first formant frequency of Dw1, Dw2, Dw3, Dw4, |
Dw5, Dw6 and store as , , ,, and or Find first formant frequency of SW1, SW2, SW3, SW4, |
SW5, SW6 and store as , , , , and |
(5) Load PNN1 |
(6) Decide VOWEL-A |
If Dw1 = VOWEL-A and = F1 of vowel |
else if |
Dw2 = VOWEL-A and = F1 of vowel |
else if |
Dw3 = VOWEL-A and = F1 of vowel |
else if |
Dw4 = VOWEL-A and = F1 of vowel |
else if |
Dw5 = VOWEL-A and = F1 of vowel |
else if |
Dw6 = VOWEL-A and F1 of vowel |
else Decide |
“Not Assamese vowel Phoneme /i/”. |
or |
Decide VOWEL-A |
If SW1 = VOWEL-A and F1 of vowel |
else if |
