    Technology is forever changing the way we get our news. Many people now get a lot of their news on electronic devices, instead of traditional media, such as newspapers, television or radio. Now, there is a new way we get the news: computer-created news readers.

Recently, China's Xinhua launched (推出) the world's first AI news presenters with the Chinese search engine Sogou. The news readers created by machine learning technology are based on two real-life newsmen. One is able to present newscasts in English; the other, in Mandarin Chinese.

One Xinhua's report said machine learning was used to examine video images and sounds of the two newsmen, which look and sound like real people.

Some machine learning experts said the system showed off China's latest progress in voice recognition, text-to-speech technology and data analysis. But several experts suggested that the term AI does not correctly describe abilities of the robotic news readers.

On social media, many Chinese noted that the AI presenters did not seem real. People blamed them for not being more lifelike. Others wondered about the effects robots might have on employment and workers. Some people argued that only low-level jobs requiring heavy labor will be easily replaced by robots. Others praised the technology as a way for companies to make money from low-cost labor machines.

Some businesses have experimented with similar technology for possible use in news operations. Britain's BBC recently released a video that used machine learning to make it look like one of its news readers speaking different languages. The London-based company that developed the system says its goal is to "remove the language barrier" for many different kinds of video across the Internet.
