In this paper, we describe a new speech/non-speech classification method that improves the endpoint detection performance for speech recognition in noisy environments. The proposed method uses multiple features to increase the robustness in noisy environments, and the classification and regression tree(CART) technique is applied to effectively combine these multiple features for classification ...

The production of haploid gametes is essential for sexual reproduction in most eukaryotes. To achieve this haploid production, germline cells enter a specialized cell cycle called meiosis, in which two consecutive chromosome segregation events create gametes with half the number of chromosomes of diploid cells. Sister chromatids are held together by cohesins along the length of their arms and a...

On-line failure detection is an essential means to control and assess the dependability of complex and critical software systems. In such context, effective detection strategies are required, in order to minimize the possibility of catastrophic consequences. This objective is however difficult to achieve in complex systems, especially due to the several sources of non-determinism (e.g., multi-t...

Speech processing is the study of speech signals, and the methods used to process them. In application such as speech coding, speech synthesis, speech recognition and speaker recognition technology, speech processing is employed. In speech classification, the computation of prosody effects from speech signals plays a major role. In emotional speech signals pitch and frequency is a most importan...
