Stress has effect on speech characteristics and can influence the quality of speech. In this paper, we study the effect of SleepDeprivation (SD) on speech characteristics and classify Normal Speech (NS) and Sleep Deprived Speech (SDS). One of the indicators of sleep deprivation is ‘flattened voice’. We examine pitch and harmonic locations to analyse(More)
This paper is to show a representation of fundamental frequency (F0) using continuous wavelet transform (CWT) for prosody modeling in emotion conversion. Emotional conversion aims at converting speech from one emotion state to another. Specifically, we use CWT to decompose F0 into a five-scale representation that corresponds to five temporal scales. A(More)
This paper describes our recent efforts in exploring effective discriminative features for speaker recognition. Recent researches have indicated that the appropriate fusion of features is critical to improve the performance of speaker recognition system. In this paper we describe our approaches for the NIST 2006 Speaker Recognition Evaluation. Our system(More)
Recently, a number of voice conversion methods have been developed. These methods attempt to improve conversion performance by using diverse mapping techniques in various acoustic domains, e.g. high-resolution spectra and low-resolution Mel-cepstral coefficients. Each individual method has its own pros and cons. In this paper, we introduce a system fusion(More)
Large-capacity wind power will have impact on transmission line protection when short circuit occurs. This paper built the dynamic simulation model of different wind turbine generator through physical devices, and tested through operation and faults. By analysis of characteristics of wind farm model, this paper analyzed the influences of wind power to(More)
Singing voice synthesis has found numerous applications in the entertainment industry over the recent years. The template-based personalized singing voice synthesis method is a new method of generating high quality singing voice, which synthesizes the singing voice by means of conversion from the narrated lyrics of a song. In this synthesis method, template(More)
We provide the raw data for protein and peptide identification and quantization of superior and inferior spikelets in hybrid rice during grain filling. The mass spectrometry proteomics data have been deposited to the Proteome Xchange Consortium via the PRIDE partner repository with the dataset identifier PXD001046. Our data presented here is also related to(More)
