A novel interactive educational toy, namely a spelling robot, is provided. The spelling robot mainly contains a command detection unit, an interpretation unit, and an action unit. The command detection unit is the input interface for the spelling robot that accepts the "word" to be spelled. The interpretation unit is the brain of the spelling robot which interprets the "word" command issued to it by the command detection unit. The result of interpretation is directed to the output interface of the spelling robot, the action unit, which actually delivers the spelling. The action unit may also contain a voice unit which actually pronounces the "word."
