For example, the term “really” can be used to question a fact or emphasize and stress out a statement in both positive and negative ways. However, with deep learning making up most of the new literature, the results are going up from around 70 % accuracy to the upper 90s in controlled environments.Īutomatic SER helps smart speakers and virtual assistants to understand their users better, especially when they recognize dubious meaning words. Before the extensive employment of deep learning, SER was relying on methods like hidden Markov models (HMM), Gaussian mixture models (GMM), and support vector machines (SVM) along with lots of preprocessing and precise feature engineering. Īlong with all major problems in machine learning, SER has started to gain an advantage from the tools made available by deep learning. Currently, this part of human–computer interaction has not yet entirely been solved, and except for a limited number of applications, there is no general solution to this problem. Understanding one’s feelings at the time of communication is constructive in comprehending the conversation and responding appropriately. Human computer interaction is characterized as consisting of five major areas of study: research into interactional hardware and software, research into matching models, research at the task level, research into design, and research into organizational impact. Speech emotion recognition is the task of recognizing emotions from speech signals this is very important in advancing human–computer interaction:
