A speech emotion recognition software application

Govor je ljudima primarni način komunikacije, a emocije koje se njime prenose pomažu boljem međusobnom razumijevanju. Zbog sve učestalije komunikacije između ljudi i strojeva, postaje bitno da i strojevi budu u mogućnosti prepoznati ljudske emocije. U ovom radu napravljeno je softversko rješenje virtualnog agenta koji prepoznaje emocije na temelju govora. U tu svrhu korištene su akustičke i lingvističke značajke govora. Najvažniji dio softvera čine umjetne neuronske mreže koje su učene na dostupnim bazama podataka. Izrađeni softverski model eksperimentalno je evaluiran na ljudskim subjektima.Speech is primary means of communication between people, and the emotions it conveys help them to better understand each other. Due to more frequent communication between humans and machines, it is becoming important for machines to be able to recognize human emotions as well. In this paper, a software solution of a virtual agent which recognizes emotions based on speech is developed. For this purpose, acoustic and linguistic speech features were used. The most important part of the software consists of artificial neural networks which have been trained on available databases. The developed software model was experimentally evaluated on human subjects
