Abstract: Speech is the most common and efficient mode of communication and has large potential of being a mode of interaction with machine/computer. To communicate with the machine via speech we require an interface which replicates the human auditory system. An Automatic Speech Recognition (ASR) system is required which is able to \"hear,” understand,\" and \"act upon\" spoken information. This paper focuses on developing the speech recognition module and integrating it with robotics wirelessly. Our goal is to develop an interactive robot which performs actions in accordance with the voice commands communicated wirelessly to the robot after being processed in the ASR module which is speaker dependent and has a pre-defined command set The system would support many valuable applications like replacing a human assistant with a robot which can perform actions according to voice command in more efficient manner.

Abstract: Reconfigurable antennas have ability to adjust their geometry and behavior to get used to changes in environmental conditions or system requirements. Such as enhanced bandwidth, change in operating frequency, polarization, radiation pattern etc. This paper discusses the use of multiband reconfigurable fractal antennas for cognitive radio once a cognitive device manages to learn the RF environment (cognition part), from past observations and decisions using machine learning techniques.
