Abstract
U radu se opisuje izrada programa za klasifikaciju izgovorenih riječi „Marvin“, „Yes“ i „No“ pomoću neuronske mreže sa dugoročnim pamćenjem (engl. Long Short Term Memory - LSTM) u programskom jeziku Python. Kao uvod u obradu i analizu audio signala opisuju se pojmovi uzorkovanja, Fourierovog reda i transformacije te diskretne Fourierove transformacije. Dobivanje korisnih informacija uz istovremeno smanjenje količine podataka ostvareno je pomoću sljedećih svojstava zvučnih signala: stopa prelaska nule, kepstralni koeficijenti po Mel-skali, spektralni centroid i spektralno opadanje. Za detaljni pregled preciznosti klasifikacijskog modela proučavalo se njegove funkcije greške i preciznosti, te klasifikacijsko izvješće i konfuzijsku matricu.
Abstract (english)
This thesis describes development of a program for classification between spoken words „Marvin“, „Yes“ and „No“ using Long Short Term Memory (LSTM) neural network in Python programming language. As an introduction to the area of audio signal analysis and processing, description of following terms is provided: Fourier series, Fourier transform and discrete Fourier transform. Features that are used as a measure of acquiring useful information and data reduction of audio signal are the following ones: zero crossing rate, Mel-Frequency Cepstral Coefficients, spectral centroid and spectral rolloff. Precision and loss functions with classification report and confusion matrix are shown as a measure of detailed overview of classification model accuracy.
