Requirements of today’s pedagogy involve focusing on forming the competences as teaching process finalities. In case of language learning it involves formation and development of communicative competences. To master a language means to be able to be a participant in the communication process in it. The concept of mastering a foreign language is primarily related to the oral aspect of communication in it. Most experts in linguistics and language teaching agree that the phonetic and phonological aspect of language is of prime importance. The influence of the native language or that of a different foreign language studied previously or simultaneously as a basic foreign language is the main cause of typical mistakes in learning pronunciation. To overcome it, there is a need of comparative and contrastive analysis of the sounds of these languages. The process of assimilation of pronunciation-related learning material includes three levels: knowledge, application and integration (the formation of knowledge, abilities and skills respectively). In this context, this paper addresses some aspects of teaching English complex consonantal monophonemic units to Romanian-speaking students.
