Virtual Environments and intelligent agents that interact within are a field that can have a lot of applications. One of the agents’ knowledge characteristics is their ability to interact with each other as well as with users that enter the same virtual environments. To make the simulation of this communication better the intelligent agent should be able to interact using natural language. Within this postgraduate dissertation a virtual environment is imported in the REVE Worlds system using VERL. Intelligent Agents interact in it who have been given the ability to create and comprehend natural language through an ELIZA-type system. Finally to achieve an even more realistic simulation Speech generation technology is applied to the intelligent agent so that the natural language produced is converted to sound. There is a study of the various speech generation systems as well as systems that convert text to speech, the technology involved and the algorithms that are being used. The FreeTTS system is thoroughly analyzed as it is the system on which the text to speech generation capabilities of the intelligent agents are based. All of the above are combined in a request fulfillment scenario of an intelligent agent that includes the actions of two more. Their communication based solely on natural language that is converted to speech. Finally there is a short description of future projects that could be developed in order to expand and improve the communication model that is studied in this dissertation.
