Then, separated vowels were manually divided to begging and centre vowel parts from which glottal pulses were estimated by DIF and IAIF methods.
Method 4 for IAIF, vowels' beginning, normalised sound
Method 8 for IAIF, vowels' centre, normalised sound.
By the comparison of eight different glottal pulse estimation methods and four classifiers, the GMM classifier can be marked as the best for stress recognition with method estimating glottal pulses by IAIF algorithm from normalised sound vowel's beginning.
