As we all know there are many languages in our world depending on their geographical location, so to remove this language differences or language barrier ,here we explain language translator system in this paper. It focuses on the translator system from English to Bengali and vice versa using machine translation. Bangla is widely spoken language and it is the fifth most spoken native language and the seventh most spoken language by the overall variety of speaker in the world. But there are only a few researches in Machine Translation (MT) for Bangla have been seen in the literature previously. Therefore this paper represents to explain a MT system for English-Bangla and BanglaEnglish translation. Our focus is to help the students to feel a comfort to understand their lesson in different languages. Machine Translation is a revolutionary technology , and day by day it improves. The newest phase of machine translation is Neural Machine Translation (NMT), which is based on the development of artificial intelligence. In this paper we are proposed a type of English-Bangla language translator which based on the Encoder-Decoder model of NMT.
