Speech emotion recognition is an important issue in the development of human-computer interactions. In this paper a series of novel robust features for speech emotion recognition is proposed. Those features, which derived from the Hilbert-Huang transform (HHT) and Teager energy operator (TEO), have the characteristics of multi-resolution, self-adaptability and high precision of distinguish abil...

This paper investigates whether the efficiency effect of product market dispersion is a function of the infrastructural and policy environment. We hypothesize that more developed transportation and communication infrastructure and lower government regulation may reduce transaction costs, intensifying the competition associated with a given market structure, and we use data from the recently lib...

Imagine a world where government regulation of gasoline, justified by scarcity of supply, allowed 20% of the gasoline in the U.S. to be used for farming; 20% for manufacturing; 20% for home use; 20% for government; and another 20% held in reserve for future potential government uses. In this world, prices would regulate the use of gasoline within each sector, but consumers would pay vastly diff...

Propelled by a national concern with social justice and health disparities, the notion of cultural competency is being incorporated into both government regulation and professional standards. Although most of the standards that are being developed nationally apply at the institutional level, it is in the clinical setting where the expectation of cultural competency is the most demanding. The re...

This feature explores the operation of individual markets. Patterns of behavior in markets for specific goods and services offer lessons about the determinants and effects of supply and demand, market structure, strategic behavior, and government regulation. Suggestions for future columns and comments on past ones should be sent to James R. Hines Jr., c/o Journal of Economic Perspectives, Depar...

Textual information is an important communication medium contained rich expression of emotion, and emotion recognition on text has wide applications. Word emotion analysis is fundamental in the problem of textual emotion recognition. Through an analysis of the characteristics of word emotion expression, we use word emotion vector to describe the combined basic emotions in a word, which can be u...
