Abstract
This paper proposes a discriminative training algorithm for autonomous speech evaluation of computer English. Firstly, the mathematical expression of discriminative training algorithm is defined, and the conditions of using the algorithm are deduced. To facilitate the discriminant training algorithm calculation, through the parameter usage and frequency to calculate the algorithm, thus simplifying the discriminative training algorithm for English speech evaluation method. Experimental results show that the proposed discriminative training algorithm is correct for computer English speech independent evaluation.
Highlights
Computer English speech refers to the independent evaluation rules have been set on the basis of good, all kinds of interactive [1] and other subjects of environmental development, through the initiative to achieve the interaction of information feedback, in order to fully assess the results of computer English pronunciation [2], the need for independent assessments of the information obtained, to improve their English pronunciation the level of [3,4]
Combined with the existing research results, this paper proposes a computer English speech autonomous evaluation system based on discriminative training algorithm under the condition of performance constraints
A discriminative training algorithm is proposed for the computer English speech independent evaluation system, and the mathematic principle, concrete expression formulas and evaluation methods of the algorithm are described in detail, and the idea of further optimizing the discriminative training algorithm is put forward
Summary
Computer English speech refers to the independent evaluation rules have been set on the basis of good, all kinds of interactive [1] and other subjects of environmental development, through the initiative to achieve the interaction of information feedback, in order to fully assess the results of computer English pronunciation [2], the need for independent assessments of the information obtained, to improve their English pronunciation the level of [3,4]. The computer English voice evaluation is a short time development area, and more attention is paid to the research and analysis of computer English voice problems based on the discriminative training algorithm [6]. Combined with the existing research results, this paper proposes a computer English speech autonomous evaluation system based on discriminative training algorithm under the condition of performance constraints. Of use, and the use of the experiment is validated and analyzed, these for future research is of significance
