An Appraisal on Speech and Emotion Recognition Technologies based on Machine Learning

Abstract: In earlier days, people used speech as a means of communication or the way a listener is conveyed by voice or expression. But the idea of machine learning and various methods are necessary for the recognition of speech in the matter of interaction with machines. With a voice as a bio-metric through use and significance, speech has become an important part of speech development. In this article, we attempted to explain a variety of speech and emotion recognition techniques and comparisons between several method… Show more

“…Subsequently, in the process, a gray filter is applied to eliminate the different color channels to later detect some important parts of the face such as the nose, eyes, eyebrows, and mouth [39], [40]. By applying a facial point technique, it is possible to detect an initial reference point in the center of the nose and to identify various facial points on parts of the face [41].…”

“…At present, many domestic and foreign researchers are devoted to the research of multi-modal fusion emotion recognition. But most of them use traditional feature extraction methods, such as Hidden Markov Model (HMM) and Gaussian mixed Model (GMM) models (Andy and Kumar, 2020). aimed at the detection and classification of microcalcification clusters by computer-aided diagnosis systems, using an adaptive GMM model to extract spatial distribution statistical features, which has high accuracy.…”
