Abstrak/Abstract |
Vowel recognition is the most important part of
the speech recognition process. Most spoken speeches must
contain vowels to be sounded. It needs a method that can
separate a vowel with another. The methods of the feature
extraction on time domain, frequency, cepstrum, and fourier are
several basic methods that can be used. This paper compares
features of the strengths of the feature of zero crossing rate,
energy, spectral centroid, spectral spread, spectral entropy,
harmonic ratio, fundamental frequency, cepstrum, and fourier to
separate and recognize vowels of a, i, u, e, and o in Indonesian
dialect/language. The results show that the spectral spread
feature that is one of the features in the frequency domain has the
most accurate ability to recognize vowels tested compared to
other features. |
