Development of automatic speech recognition system for voice activated Ground Control system

This paper gives details of the development of a speech recognition system for voice activated Ground Control Station (GCS). The speech recognition is implemented using MATLAB and the results are validated against the Hidden Markov Model Tool Kit (HTK), an open source tool for speech recognition. The menu items of Mission planner, a typical open source GCS used for flying of Micro Air Vehicles (MAV) are used for the experiments.
