Abstract(in English) Emotional aspect plays an important role in user interface. We deal with five emotions that are "anger", "surprise", "sadness", "dislike" and "joy". We verify whether one can feel each emotion from speech of a word that is synthesized with characteristics of each emotion. Those characteristics are represented by three parameters of tempo, pitch and volume of speech. As a result, we get a correct answer with a high rate of 85% in "anger", "dislike" and "sadness". This result validates the value of the parameters for those emotions. On the other hand, in "joy" and "surprise", we hypothesize that it is difficult to distinguish these two emotions only by its prosody. Preliminary experiments in which four emotions are attached to a word by a native French show that emotion patterns are somewhat language dependent.
