It is difficult to determine which language is the most accurate when using Google Translate as accuracy varies depending on the language pair and content type. However, Google Translate is generally considered to be very accurate, with some reports showing it reaching 94 accuracy. Google's shift to Neural Machine Translation in 2016 has greatly improved the accuracy of the tool, particularly for the two most used language pairs, Spanish-English and French-English, where accuracy increased to 85. DeepL and Google Translate are currently the most popular generic machine translation engines on the market, with Google Translate ranking highest out of 18 generic engines for most language pairs.
