“…The sound will not be natural enough. If the highest normal correlation is obtained from the high-pass filtered speech signal, the position of the complex signal is marked as 1, indicating that there is a complex signal [14]. Background noise estimation: the background noise estimation is updated by the input amplitude level of the 5 Wireless Communications and Mobile Computing previous speech signal frame.…”

Chinese speech synthesis refers to the technology that machines transform human speech signals into corresponding texts or commands through recognition and understanding. This paper combines the classic VAD and GSM VAD1 algorithm simulations, improves on the above two algorithms to recognize and collect speech, and analyzes their Chinese proficiency by amplifying the signal through a filter, in order to study the adulthood of Zhengzhou University in Southeast Asian students (mother tongues are Indonesian and Thai) as the research objects, to explore the relationship between the Chinese phonetic proficiency and the acquisition motivation of Southeast Asian students. This article combines algorithm and language disciplines. According to the results of Praat and SPSS: 55-80 points account for 70%, 55 points below 20% and 80 points above 10%, we find that intrinsic motivation plays a role in CSL acquisition, a vital role. Intrinsic motivation can help mature learners from Southeast Asia to acquire Chinese better and better. The earlier you learn Chinese, the higher your motivation, and the easier it is to set your Chinese learning goals. The greater the enthusiasm for learning Chinese, the better the Chinese scores (such as HSK test scores and Chinese phonetic test scores). Therefore, the Chinese proficiency of international students has a great relationship with their interest in Chinese language, that is, the greater the interest in Chinese, the stronger their motivation to learn, and the Chinese proficiency will be very good.

Purpose Analytical methods are widely used in heat and fluid flow; the purpose of this paper is to couple Taylor series method and Bubbfil algorithm to solve nonlinear differential equations. Design/methodology/approach A series solution is obtained with some unknown constants, which can be determined by incorporating boundary conditions, and the constants are calculated by the Bubbfil algorithm. Findings This paper gives an analytical approach to a nonlinear equation arising in porous catalyst using Taylor series and Bubbfil algorithm, and a high accuracy can be achieved. Research limitations/implications The coupled method of Taylor series and Bubbfil algorithm is a powerful method for nonlinear differential equations. Practical implications The proposed technology can be used in various numerical methods. Originality/value A new analytical method is proposed based on Taylor series and Bubbfil algorithm, which is a development of Newton’s iteration method and an ancient Chinese algorithm. The solution process is simple and easy to follow.

“…[20][21][22][23][24][25]29 The most important feature of a nonlinear oscillator is the relationship between frequency and amplitude, and He's frequency formula 28,29 is a simple method to estimate this relationship, which was initially inspired by an ancient Chinese algorithm. [29][30][31][32] Duffing oscillator was first proposed by Duffing in 1918 to investigate the vibration of the electromagnetic vibrating beam, 33 it can be written in the form with a damping coefficient l and a nonlinear coefficient Q: Here k is the wave number of the traveling wave. This equation seems simple but has complex dynamic behaviors.…”

Nonlinear oscillation is an increasingly important and extremely interesting topic in engineering. This article completely reviews a simple method proposed by Ji-Huan He and successfully establishes a fractal undamped Duffing equation through the two-scale fractal derivative in a fractal space. Its variational principle is established, and the two-scale transform method and the fractal frequency formula are adopted to find the approximate frequency of the fractal oscillator. The numerical result shows that He’s frequency formula is a unique tool for the fractal equations.
