This paper makes an analysis and researching on Tibetan text and dialects speech. And implement the computer programs on windows system. It also provides a theoretical support and application tools for in-depth study .This paper mainly including several aspects as following: 1)The collection and collation of the Tibetan words; 2) confirmed dialect(More)
Respiratory signal is an important physiological speech signal, which plays an important role in the study of multi-modal of speech. But there is still lack the software with the function of respiratory signal processing. Thus, based on a large number of analysis and in-depth research, this paper puts forward a set of systemic respiratory signal parameters,(More)
In order to boost the convergence speed of Genetic algorithms (GAs), some amelioration was made on the standard Genetic algorithm, a new crossover and a new mutation were designed in this paper. According to the numerical tests, the convergence speed of ameliorated Genetic algorithms accelerated apparently. In the Rae2822 supercritical airfoil drag(More)
Without language competence, cry is a special way that infant express individual needs and response to outside. In this paper, we chose two infants as examinee, measuring fundamental frequency of crying sound section. We developed speech signal analysis platform, and through the analysis we found that infant have falling tone, flat tone, rising tone,(More)
In this paper, based on Motor Speech Profile and combined with the normative data of DDK parameters in American adults, we tested 11 parameters of DDK, such as Average DDK Period, Average DDK Rate, Standard Deviation of DDK Period, Coeff.of Variation of DDK Period, Perturbation of DDK Period, Average DDK Peak Intensity and so on. According to our researches(More)
Nasal flow signal is a kind of important physiological signals, the framework of this article is based on the achievements of traditional phonetics, we design and relies nasal acoustic analysis platform in the Mat lab environment. Proposed a set of nasal flow signal parameters which including nasal sound energy, oral sound energy, duration, nasal degrees,(More)
