Machine translation, also known as robotized interpretation, is the process in which computers or machines independently and quickly translate vast volumes of text from a particular source language to a target language without any effort put in by human beings. In other words, machine translation functions by employing an application that helps translate text from one input language to another. There are four different types of machine translation in NLP: statistical machine translation, rule-based machine translation, hybrid machine translation, and neural machine translation. The main advantage of machine translation is its delivery of an effective combination of both speed and cost-effectiveness.
