Robbie the Robot... Ever wanted to have a conversation, vocally, with a machine? Now you can! Robbie the Robot is a computer program for Mac OS 10.5 designed by Erin Kennedy in Grade 11. This computer program demonstrates a human-machine conversation using speech synthesis and natural language processing. With the use of language models and pre-programmed responses, Robbie has the ability to converse for a long time, while being able to reflect on past responses, then slowly transition into new sub-conversations.
