Google has a translator app where the user can point a camera on any sign or text and it will translate to a language of choice on top it. This works by using what Google calls, neural machine translation (NMT). The software supports instant camera translation.
Recently google has released a new update which fixes a lot of technical issues, such as making the text less jumpy. It also reduces errors in the final translations by as much as 85 percent. And lastly it has added support for over 60 languages, something that was limited when the service was first launched. New languages supported in the update include: Afrikaans, Arabic, Bengali, Estonian, Greek, Hindi, Igbo, Javanese, Kurdish, Latin, Latvian, Malay, Mongolian, Nepali, Pashto, Persian, Samoan, Sesotho, Slovenian, Swahili, Thai, Vietnamese, Welsh, Xhosa, Yoruba, and Zulu.
This is all done because of the enchancement and updates they made to the NMT. Google has said that the update for everyone will be out soon.
