Emotion recognition in speech signal using emotion- extracting binary decision trees
نویسندگان
چکیده
The presented paper is concerned with emotion recognition based on speech signal. Two novel elements introduced in the method are an introduction of novel set of emotional speech descriptors and an application of a binary-tree based classifier, where consecutive emotions are extracted at each node, based on an assessment of feature triplets. The method has been verified using two databases of emotional speech on German and Polish, yielding very high recognition rates (72 %) for speaker-independent recognition.

Classification of emotional speech using spectral pattern features
Speech Emotion Recognition (SER) is a new and challenging research area with a wide range of applications in man-machine interactions. The aim of a SER system is to recognize human emotion by analyzing the acoustics of speech sound. In this study, we propose Spectral Pattern features (SPs) and Harmonic Energy features (HEs) for emotion recognition. These features extracted from the spectrogram ...

Abstract Recent developments in robotics automation have motivated researchers to improve the efficiency of interactive systems by making a natural man-machine interaction. Since speech is the most popular method of communication, recognizing human emotions from speech signal becomes a challenging research topic known as Speech Emotion Recognition (SER). In this study, we propose a Persian em...
متن کاملApplication of Poincare-Mapping of Voiced-Speech Segments for Emotion Sensing
The following paper introduces a group of novel speech-signal descriptors that reflect phoneme-pronunciation variability and that can be considered as potentially useful features for emotion sensing. The proposed group includes a set of statistical parameters of Poincare maps, derived for formant-frequency evolution and energy evolution of voiced-speech segments. Two groups of Poincare-map char...
متن کاملExtracting Emotion from Speech: Towards Emotional Speech-Driven Facial Animations
Facial expressions and characteristics of speech are exploited intuitively by humans to infer the emotional status of their partners in communication. This paper investigates ways to extract emotion from spontaneous speech, aiming at transferring emotions to appropriate facial expressions of the speaker’s virtual representatives. Hence, this paper presents one step towards an emotional speechdr...
متن کاملImproving of Feature Selection in Speech Emotion Recognition Based-on Hybrid Evolutionary Algorithms
One of the important issues in speech emotion recognizing is selecting of appropriate feature sets in order to improve the detection rate and classification accuracy. In last studies researchers tried to select the appropriate features for classification by using the selecting and reducing the space of features methods, such as the Fisher and PCA. In this research, a hybrid evolutionary algorit...
