Google has announced enhancements to its neural machine translation (NMT) technology, allowing it to run Google Translate applications offline, on users' devices. The technology will allow users to 'get high-quality translations' even when they are not connected to the Internet. The artificial intelligence (AI) system that powers it allows the translation of 'whole sentences at a time', and it 'uses broader content to help determine the most relevant translation, which it then rearranges and adjusts to sound more like a real person speaking with proper grammar'. To use the new technology, users will have to download language sets on their devices, and Google explains that each such set is around 35-35MB. The tool is to be made available in 59 languages.
