In order to improve the effect of English teaching practice, this paper constructs an intelligent English phonetic teaching system combined with the method of phonetic feature parameter recognition. Moreover, this paper simulates the self-mixing interference signal containing noise by establishing a simulation, analyzes the size of the noise and its various possibilities, and selects the EEMD method as the English speech denoising algorithm. In addition, with the support of an intelligent denoising algorithm, this paper implements an English intelligent teaching system based on the recognition algorithm of English speech feature parameters. Finally, this paper evaluates the teaching effect of the intelligent English speech feature recognition algorithm proposed in this paper and the intelligent teaching system of this paper by means of simulation teaching. The research shows that the English teaching system based on the intelligent speech feature recognition algorithm proposed in this paper has a good effect.

This review strives to shed light on the related studies on the relationship between English as a Foreign Language (EFL) teachers' personality traits, communication strategies, and their work engagement. The positive correlation between teachers' personality traits and work engagement has been confirmed in the review of the literature. Furthermore, studies have proved the relationship between teachers' communication strategies and personality traits. No studies have been done on the direct relationship between teachers' communication strategies and work engagement. However, the studies showed that some factors, such as teacher self-efficacy and willingness to communicate, can mediate the relationship between teachers' communication strategies and work engagement. To improve the language teaching quality, the pedagogical implications are explained in the end. Some suggestions for further research are provided to expand the literature about teachers' communication strategies, work engagement, and personality traits.
