A demonstration at a Tokyo museum was held on Tuesday where two human androids displayed their ability to speak by delivering the news to a room of reporters.

It was a big triumph as the female teen-like robot read the news without stumbling. These robots are called Kodomoroid - a word formulated by amalgamation of the words "Kodomo" (child) and android. Such robots are used as the new guides in the Tokyo museum, they speak and look almost like humans.

Hiroshi Ishiguro, an Osaka University professor and a Japanese robotics expert, says that such a thing would be useful on doing research on the fact that how people interact with robots and on what differentiates the person from such machine.

The Kodomoroid robot is designed with a girlish appearance and can use a variety of voices like deep male voice or a squeaky girly voice. The speech can be input by text which gives them perfect articulation.

There is another set of adult woman robot called the Otonaroid; this comes from the Japanese word "Otona" (adult), admitted to being "a little bit nervous". These are announcer robots that stay silent twice when asked for an introduction.

Further the above two robots were joined by the minimally designed Telenoid, which is a mannequin head with pointed arms that serve as a cuddly companion.

"Making androids is about exploring what it means to be human, examining the question of what is emotion, what is awareness, what is thinking", Ishiguro told reporters while commenting about this demonstration.

He is into developing robots for over 20 years now and has succeeded in creating robots that approximate the human appearance, including creatures that look like him and went to give overseas lectures on his behalf.
