English translation, also a kind of language conversion, refers to the activities of expressing each other in English to express another language or another language to express English. ,is paper aimed to evaluate and research methods of English translation based on the improved Gaussian mixture model (GMM). ,e paper proposed a simple evaluation and analysis of English translation using a discriminative training algorithm. In the experimental part, on the one hand, taking students, teachers, and translators as case study objects, through a questionnaire survey, it can be known that the number of students who scored more than 80 points in the English translation test is increasing every year, from 11.30% in the ﬁrst year to 21.13% in the fourth year, an increase of nearly 10%. On the other hand, it can be seen from the speech translation experiment that the correct translation rate was 46.18% by using intelligent technology to distinguish translation. ,e experimental results showed that the discriminative training algorithm under the improved GMM algorithm is eﬀective in the research of English translation evaluation.

According to the analysis of this questionnaires, it was found that the English translation paper, the application of the discriminative training algo- rithm of GMM in English translation is relatively perfect. ability of all kinds of people was relatively strong, but in the voice translation, their translation ability was still weak. With the advancement of science and technology, intelligent translation technology has gradually been recognized and ,is paper is devoted to researching the related application of the discriminative training algorithm based on GMM and used by the public. ,e use of GMM’s discriminative applying it in the ﬁeld of English translation evaluation. ,is is training algorithm to collect the opinions of English not only an expansion and extension of the application scope of translation professionals on the profession greatly facilitates the algorithm, but also a new attempt to evaluate English the research of this experiment. However, because the re- translation. ,rough the above case studies, opposite experi- search in this ﬁeld is not comprehensive enough, there are mental results are obtained in the written translation experi- some small problems, which need to be corrected. ,e details are as follows: First, in the questionnaire survey, three ment and the speech translation experiment, which both show the eﬀectiveness of the discriminative training algorithm in this groups of people were selected for experimental investiga- tion; the results are better, but in this part of the experiment, paper under the Gaussian mixture model. 10 International Transactions on Electrical Energy Systems wavenumber ﬁlter and its applications in least-squares seismic 6.
