The growing interest in emotional speech synthesis urges effective emotion conversion techniques to be explored. This paper estimates the relevance of three speech components (spectral envelope, residual excitation and prosody) for synthesizing identifiable emotional speech, in order to be able to customize voice conversion techniques to the specific characteristics of each emotion. The analysi...

In this preliminary report we investigate the effects of emotion on the lower lip movements during the production of a monosyllabic word in two different prosodic contexts: phrase initial and phrase final. The purpose is to examine the rigidity of the phrase boundary effects under emotional perturbation of the normal, or neutral, speech production. It is found that the effect of emotion is ubiq...

Emotional information in speech is commonly described in terms of prosody features such as F0, duration, and energy. In this paper, the focus is on how F0 characteristics can be used to effectively parametrize emotional quality in speech signals. Using an analysis-by-synthesis approach, F0 mean, range, and shape properties of emotional utterances are systematically modified. The results show th...

A corpus-based generation of fundamental frequency (F0) contours was realized for emotional speech synthesis. The method, originally developed for read speech, is to predict command values of the F0 contour generation process model with the input of linguistic information of the sentence to be synthesized. Since the generated F0 contour is under the model constraint, a certain quality is still ...

Recently, increasing attention has been directed to the study of the emotional content of speech signals, and hence, many systems have been proposed to identify the emotional content of a spoken utterance. This paper is a survey of speech emotion classification addressing three important aspects of the design of a speech emotion recognition system. The first one is the choice of suitable featur...

In this dissertation the practical speech emotion recognition technology is studied, including several cognitive related emotion types, namely fidgetiness, confidence and tiredness. The high quality of naturalistic emotional speech data is the basis of this research. The following techniques are used for inducing practical emotional speech: cognitive task, computer game, noise stimulation, slee...

In this paper we overview emotional speech recognition having in mind three goals. The first goal is to provide an up-todate record of the available emotional speech data collections. The number of emotional states, the language, the number of speakers, and the kind of speech are briefly addressed. The second goal is to present the most frequent acoustic features used for emotional speech recog...

Detecting emotional dimensions [1] in speech is an area of great research interest, notably as a means of improving human computer interaction in areas such as speech synthesis [2]. In this paper, a method of obtaining high quality emotional audio speech assets is proposed. The methods of obtaining emotional content are subject to considerable debate, with distinctions between acted [3] and nat...

Emotion recognition from speech has emerged as an important research area in the recent past. In this regard, review of existing work on emotional speech processing is useful for carrying out further research. In this paper, the recent literature on speech emotion recognition has been presented considering the issues related to emotional speech corpora, different types of speech features and mo...
