Emotion Recognition from Speech with Acoustic, Non-Linear and Wavelet-based Features Extracted in Different Acoustic Conditions
(Sistemas Embebidos e Inteligencia Computacional (SISTEMIC)Medellín, Colombia, 2017)
Double Fourier analysis for Emotion Identification in Voiced Speech
(IOP PUBLISHING LTD, 2016-01-01)
We propose a novel analysis alternative, based on two Fourier Transforms for emotion recognition from speech. Fourier analysis allows for display and synthesizes different signals, in terms of power spectral density ...
Spoken emotion recognition using hierarchical classifiers
(Elsevier, 2011-07)
The recognition of the emotional state of speakers is a multi-disciplinary research area that has received great interest over the last years. One of the most important goals is to improve the voice-based human-machine ...
The classification problem in machine learning: an overview with study cases in emotion recognition and music-speech differentiation
(Universidad EAFITMaestría en IngenieríaEscuela de Ingeniería, 2015)
This work addresses the well-known classification problem in machine learning -- The goal of this study is to approach the reader to the methodological aspects of the feature extraction, feature selection and classifier ...
Emotion recognition in never-seen languages using a novel ensemble method with emotion profiles
(Institute of Electrical and Electronics Engineers, 2017-01)
Over the last years, researchers have addressed emotional state identification because it is an important issue to achieve more natural speech interactive systems. There are several theories that explain emotional ...
Cognitive problem-solving abilities and speech acts in children: an analysis in vulnerable family contexts
(Academicians' Research Center, 2015-12)
The goal of this study was to analyze the cognitive abilities involved in interpersonal problemsolving and their connection with speech acts in children from contexts of social vulnerability. The sample included 120 ...
Evaluation of wavelet measures on automatic detection of emotion in noisy and telephony speech signals
(IEEE, 2014-01-01)
Detection of emotion in humans from speech signals is a recent research field. One of the scenarios where this field has been applied is in situations where the human integrity and security are at risk. In this paper we ...
Multiresolution analysis (discrete wavelet transform) through Daubechies family for emotion recognition in speech.
(IOP PUBLISHING LTD, 2016-01-01)
We propose a study of the mathematical properties of voice as an audio signal. This work includes signals in which the channel conditions are not ideal for emotion recognition. Multiresolution analysis- discrete wavelet ...
