WPŁYW FUNKCJI OKNA NA SKUTECZNOŚĆ IDENTYFIKACJI STANU EMOCJONALNEGO MÓWCY

The article presents the impact of window function used for preparing the spectrogram, on Polish emotional speech identification.. In conducted researches the following window functions were used: Hamming, Gauss, Dolph–Chebyshev, Blackman, Nuttall, Blackman-Harris. The spectrogram processing method by artificial neural network (ANN) was also described in this article. Obtained results allowed to assess the effectiveness of identification process with the use of ANN. The average efficiency ranged from 70 % to more than 87%.Artykuł prezentuje wpływ doboru funkcji okna wykorzystywanej w procesie obliczania spektrogramu, na skuteczność identyfikacji stanu emocjonalnego mówcy posługującego się mową polską. W badaniach wykorzystano następujące funkcje okna: Hamminga, Gaussa, Dolpha–Czebyszewa, Blackmana, Nuttalla, Blackmana-Harrisa. Ponadto został przedstawiony sposób przetwarzania spektrogramu przez sztuczną sieć neuronową (SSN), odpowiedzialną za identyfikację stanu emocjonalnego mówcy. Otrzymane wyniki pozwoliły na ocenę skuteczności rozpoznawania stanu emocjonalnego za pomocą SSN. Średnia skuteczność wahała się od około 70% do ponad 87%

A Comprehensive Study on State-Of-Art Learning Algorithms in Emotion Recognition

The potential uses of emotion recognition in domains like human-robot interaction, marketing, emotional gaming, and human-computer interface have made it a prominent research subject. Better user experiences can result from the development of technologies that can accurately interpret and respond to human emotions thanks to a better understanding of emotions. The use of several sensors and computational algorithms is the main emphasis of this paper's thorough analysis of the developments in emotion recognition techniques. Our results show that using more than one modality improves the performance of emotion recognition when a variety of metrics and computational techniques are used. This paper adds to the body of knowledge by thoroughly examining and contrasting several state-of-art computational techniques and measurements for emotion recognition. The study emphasizes how crucial it is to use a variety of modalities along with cutting-edge machine learning algorithms in order to attain more precise and trustworthy emotion assessment. Additionally, we pinpoint prospective avenues for additional investigation and advancement, including the incorporation of multimodal data and the investigation of innovative features and fusion methodologies. This study contributes to the development of technology that can better comprehend and react to human emotions by offering practitioners and academics in the field of emotion recognition insightful advice
