      Speech is one of the common modes of communication and it is a process of transferring information from one entity to another. In recent years there has been much research on unvoiced/voiced classification and voice ...

    • Human Affective (Emotion) behaviour analysis using speech signals: A review 

      M. N., Hasrul; M, Hariharan, Dr.; Sazali, Yaacob, Prof. Dr. (Institute of Electrical and Electronics Engineers (IEEE), 2012-02-27)
      Affective (Emotional) state of a person is very important in medical application due to the fact that it can indicate the stress level of an individual. This can be done through manipulating the speech signal of individual ...

    • Multistyle classification of speech under stress using wavelet packet energy and entropy features 

      Nurul Aida Amira, Johari; Hariharan, Muthusamy, Dr.; Saidatul, A.; Sazali, Yaacob, Prof. Dr. (IEEE Conference Publications, 2011-10)
      Physco-physiological conditions like stress and emotional state may affect human's speech production. Different techniques have been proposed such as facial expressions, speech production variation, and physiological signals ...
