“…However, lately, by the development of deep learning tools and processes, solutions for SER can be changed as well. There is a lot of effort and research on employing these algorithms to recognize emotions from the speech [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. In addition to deep learning, more recently, along with improvements in recurrent neural networks and the use of long short-term memory (LSTM) networks, autoencoders, and generative adversarial models, there has been a wave of studies on SER using these techniques [ 28 , 29 , 30 , 31 , 32 , 33 ] to solve the problem.…”
