Speech recognition in the JAS 39 Gripen aircraft -

During the years 2000 and 2001, the speech of eight pilots flying the JAS 39 Gripen aircraft was recorded at Saab in Linkoping. Thirty sentences were recorded on the ground and at di#erent G-loads, with a maximum of 8G. The sentences were spoken in both Swedish and English. There was also some additional material which consisted of mostly spontaneous speech. The purpose of this Masters Thesis was to perform speech recognition on the material, and also adaptation to di#erent G-loads, in order to see if this improved recognition. A reference test using a di#erent clean speech database showed that the monophone model sets used for these experiments gave good performance in clean conditions
