A critical insight into multi-languages speech emotion databases

Abstract

With increased interest of human-computer/human-human interactions, systems deducing and identifying emotional aspects of a speech signal has emerged as a hot research topic. Recent researches are directed towards the development of automated and intelligent analysis of human utterances. Although numerous researches have been put into place for designing systems, algorithms, classifiers in the related field; however the things are far from standardization yet. There still exists considerable amount of uncertainty with regard to aspects such as determining influencing features, better performing algorithms, number of emotion classification etc. Among the influencing factors, the uniqueness between speech databases such as data collection method is accepted to be significant among the research community. Speech emotion database is essentially a repository of varied human speech samples collected and sampled using a specified method. This paper reviews 34 `speech emotion databases for their characteristics and specifications. Furthermore critical insight into the imitational aspects for the same have also been highlighted.

“…The governing equations of forget gate, input gate, output gate, and cell state are presented in Eq. (12). where f t ,i t , o t and c t are the forget gate, input gate, output gate, and cell gate, respectively, σ is the sigmoid activation function, S t−1 is the previous states, X t is the input at time t, W f , W i and W o are a respective set of weights of the forgetgate, input gate, and output gate the intermediate cellstate defined in Eq.…”

A Comprehensive Review of Speech Emotion Recognition Systems

“…If we consider the fundamental frequency values, it is known that anger typically has a high fundamental frequency compared to the low fundamental frequency of sadness. One simple reason for this variation is the difference between the actual data and the simulated data [13]. However, other causes of variations are differences in culture, language, gender, and situations.…”
