Abstract
U ovom radu osmišljen je sustav za prepoznavanje glasovnih naredbi za NAO robota. Implementirane su glavne komponente takvog sustava. Osmišljen je i implementiran sustav za prikupljanje glasovnih naredbi u formi web aplikacije. Uspoređena su dva postupka ekstrakcije značajki iz zvučnih zapisa, te su mel-frekvencijski kepstralni koeficijenti odabrani zbog manje vremenske složenosti. Odabrana su tri klasifikatora - stroj s potpornim vektorima, k najbližih susjeda te nasumična šuma. Sva tri klasifikatora evaluirana su na istom skupu primjera, te je zaključeno kako najbolje performanse pokazuje stroj s potpornim vektorima. Cijeli sustav implementiran je u programskom jeziku Python uz korištenje više pomoćnih modula.
Abstract (english)
The paper describes a speech-recognition system for the NAO robot. The main components of such a system have been developed and implemented. The system is comprised of a speech recording web application, feature-extraction and classification. Linear predictive coding (LPC) and mel-frequency cepstral coefficients (MFCC) have been compared as two possible feature-extraction procedures, and the MFCC was chosen as the faster one. Three classification algorithms have been compared - k Nearest Neighbours (kNN), Support Vector Machine (SVM) and Random Forest, and SVM was chosen for the highest prediction accuracy. The whole system was implemented in the Python programming language, using a number of modules.
