Application ID: 11451217

Base Claim:
1. A speech activated control system for controlling aerial vehicle components, comprising: a host processor having memory and positioned in communication with a database for storing speech recognition models; and speech actuated command program product at least partially stored in the memory of the host processor and including instructions that when executed by the host processor cause the processor to perform the operations of: forming a digitized user-speech template representing a command annunciation, dividing the user-speech template into a plurality of time slices, subdividing each separate one of the plurality of time slices into a plurality of bins each associated with a corresponding different one of a plurality of frequency ranges, performing a noise reduction and speech enhancement on the digitized user-speech template to include: estimating noise power for each separate set of bins having a same frequency range across the plurality of time slices to thereby provide a plurality of frequency range-specific noise power estimates, equalizing energy values of each set of bins having a same frequency range across the plurality of time slices responsive to the respective frequency range-specific noise power estimate, and thresholding each equalized bin by a predetermined value to remove noise from within and around speech formants of the user-speech template, developing a set of feature vectors representing energy of a frequency content of the digitized user-speech template to thereby determine a unique pattern identifying the command annunciation, applying a speech recognition engine to the set of feature vectors to form at least one speech recognition model associated with the command annunciation, associating an index with the at least one speech recognition model associated with the command annunciation, and storing the at least one speech recognition model and the associated index.

Claim 9:
9. The system as defined in claim 1 , further comprising: an avionic computer in communication with the host processor and having memory and a portion of the speech actuated command program product defining a command function manager stored in the memory; and a display and control processor in communication with the avionic computer and having memory and a portion of the speech actuated command program product defining a user interface stored in the memory.
