Few studies exist on the topic of emotion encoding in speech articulatory domain. In this report, we analyze data collected during simulated emotional production and investigate differences articulation among four types; neutral, anger, sadness happiness. The movement tongue tip, jaw lower lip, along with speech, were obtained from a subject using an Electromagnetic articulography (EMA) system. effectiveness parameters classification was also investigated. A general behavior observed that emotionally elaborated exhibits more peripheral articulations when compared to neutral speech. lip positioning become advanced charged. This tendency especially prominent for tip movements associated sad Angry characterized by greater ranges displacement velocity, while it opposite Happy comparable but showed widest range pitch variation. It, however, remains be seen if there is trade-off between activity voicing production. Multiple discriminant analysis better classified One probable reason independency manipulation each articulator may provide degrees freedom less overlap parameter space. Analysis distinct effects different phonemes: high front vowel /IY/ found discriminated both acoustic domains than other vowels such as /AA/ /UW/. It likely physical boundary effect leave room vary and/or configuration vowels, resulting contrast types.
