used as a dictionary by typing in words. One can translate from a book by using a scanner and an OCR like Google Drive, but this takes about five minutes per page. In its Written Words Translation function, there is a word limit on the amount of text that can be translated at once. Therefore, long text should be transferred to a document form and translated through its Document Translate function. Moreover, like all machine translation programs, Google Translate struggles with polysemy (the multiple meanings a word may have) and multiword expressions (terms that have meanings that cannot be understood or translated by analyzing the individual word units that compose them). A word in a foreign language might have two different meanings in the translated language. This might lead to mistranslations. Additionally, grammatical errors remain a major limitation to the accuracy of Google Translate.

Reviews Shortly after launching the translation service for the first time, Google won an international competition for English–Arabic and English–Chinese machine translation. Translation mistakes and oddities Since Google Translate used statistical matching to translate, translated text can often include apparently nonsensical and obvious errors, often swapping common terms for similar but nonequivalent common terms in the other language, as well as inverting sentence meaning. Novelty websites like Bad Translator and Translation Party have utilized the service to produce humorous text by translating back and forth between multiple languages, similar to the children's game telephone.
