Babkina, V. (2018). Phonological interference of mother tongue over the English

participants missed classes regularly, which is why it did not allow the 
researcher to cover a hundred per cent of all the participants in some 
pronunciation evaluations.
3) The present research is only an attempt to help a group of 
Peruvian learners improve their English language consonant sounds 
pronunciation. There is definitely a lot more to offer the learners for 
improvement from the point of view of EFL pronunciation, such as 
length of the vowel sounds, word /sentence, intonation, connected speech 
and so on. The mentioned aspects are the ideas for further investigations.

Antecedents of the study 
 
Since the topic of influence of mother tongue in L2 learning and 
teaching has always been of a great interest among researchers, there has 
been a variety of practical works related to the subject. Each work 
undoubtedly has its value and covers various important issues. Negative 
interference of L1 on the English language pronunciation has been 
investigated from the point of view of segmental and suprasegmental 
features of the language; moreover, different teaching instruction and 
techniques have been suggested by the investigators as a solution to the 
problem.

Some researches played a significant role in the process of the 
development of the given investigation. Three papers were selected as the 
most valuable examples; the procedure of each research, the author´s 
opinion about the studies and the connection of each paper with the given 
investigation are described below.
The first important study to be mentioned is “The impact of 
instruction in phonetic and phonemic distinction in sounds on the 
pronunciation of Spanish-speaking ESL learners”, performed by Jaya S. 
Goswami at Texas A&M University, located in Kingsville, Texas, and by 
Hsuan-Yu Chen at National Kaohsiung University of Applied Science, 
located in Kaohsiung, Taiwan. The investigation was carried out in
