Abstract
A method for recognizing speech commands includes defining a time window for recognizing a speech command. A first confidence value is determined for a first recognition result. If the first confidence value is greater than or equal to a first threshold value, the first recognition result is selected as the speech command, otherwise a second recognition stage is performed where the time window is extended. A second confidence value is determined for the second recognition result. If the second confidence value is greater than or equal to the first threshold value, a command word selected at the second recognition stage is selected as the speech command, otherwise the first and second recognition results are compared to each other to determine a probability that they are substantially the same. If the probability exceeds a predetermined value, the command word selected at the second stage is selected as the speech command.
