Martina Ambrozová (2014) The thesis in hand focuses on English pronunciation difficulties among Czech speakers or learners of English, their possible causes and possible compensating strategies. It proposes four main problematic areas of English pronunciation which include seven consonants. These areas have been observed in a comparative research through the voice recordings of a native speaker and the Czech speakers of English. Furthermore, this thesis also offers several compensation strategies compiled in a form of a booklet which is also a part of the thesis.
