These machines are designed to do this kind of work quickly and without mistakes. The quality of translation software programs has greatly improved in recent years. This has led many people to start using machine translators. One of the most widely used translation devices is Google Translate. Google says the service completes billions of translation requests, involving 103 languages, each year. Google had earlier used a system that translated on phrase-by-phrase level. This system created speech that could usually be understood, but didn’t sound natural. Recently, Google announced a new system known as neural machine translation, taking entire sentences and modeling sentence outputs (输出). It produces translations that sound more like real human language. 3. What is the news mainly concerned with?
A、Machine translators.
