There are many commercial books which are advertised constantly by 
celebrities on TV since 2020 in Uzbekistan. Those advertisement are usually 
presented by celebrities and they sound very convincing. Many people, particularly

the funs of those celebrities, trust them and spend pretty amount of finance to 
purchase book. However, the question such as does those books cost such spending? 
What methods are used in those books? Is it possible to learn a foreign language in 6 
month? are a big questions for learners of foreign language. Considering those 
challenges I conducted my own research and would like to share the findings with 
others. 
Initially, I want to speak about the methodology used in those audio-books, 
which is broadly promoted in adds as “innovative and latest”.
This audio-lingual 
method was developed in the 1950 to train the military servants in the United States 
which was based on behaviorism theory. It claims that human could be trained 
through repetition and reinforcement. However this theory has been widely 
criticized in psychology and pedagogy claiming that an object cannot be controlled 
automatically by external influences (in the example of Pavlov's experiments on 
dogs). The audiolingual method is also ineffective in terms of English teaching 
methods. There is no any proved example that someone has learned to speak or 
write fluently in a foreign language in six month practicing only listening. 
Nowadays, the communicative method in learning a foreign language is the study of 
all skills and language aspects such as speaking, listening, reading, writing, 
vocabulary, grammar, phonology together. It is inadequate to say that one learn his 
mother tongue by listening, and therefore, others can learn foreign language in the 
same way. There is a big difference between a young child learning his mother 
tongue and an adult learning a foreign language, and this comparison is not 
reasonable. There are many people who immigrate oversees however, they listen 
local language everyday but some of them cannot learn how to speak or write in that 
language. Considering all above, I can say that the books mentioned above are not 
reliable sources to enhance language skills. However, there are many free resources 
such as Duolingo, Bee, Busuu, Memrise to learn foreign language. Zaylobidinova 
(2019) claimed that technology of our days is so fast moving and inexpensive that 
one can easily find free books, application, or tool in learning foreign language. 
Now, I would like to review some privileges and limitations of some mobile 
application and give my suggestions for the further improvements.
Duolingo is American language learning tool which was designed to learn 
more than 103 languages. Its mobile version creates possibilities to practice target 
language wherever it is possible. With a special tailored program one can easily 
enhance vocabulary, grammar, listening and speaking abilities. The users of
