System and method for correcting accent induced speech in an aircraft cockpit utilizing a dynamic speech database
First Claim
1. A method, executable by a processor, for recognizing speech in a speech recognition system on board an aircraft that compensates for different regional dialects over an area comprised of at least first and second distinct geographical regions, the method comprising:
- analyzing speech in the first distinct geographical region using speech data characteristics representative of speech in the first distinct geographical region, wherein analyzing the speech data characteristics comprises referencing at least one of an acoustic model, a phonetic dictionary, and a language model in the speech recognition system on board of the aircraft;
detecting a change in position from the first distinct geographical region to the second geographical region; and
analyzing speech in the second distinct geographical region using speech data characteristics representative of speech in the second distinct geographical region upon detecting that the aircraft has transitioned from the first distinct geographical region to the second distinct geographical region.

6. A method, executable by a processor, for recognizing speech in a speech recognition system on board an aircraft that compensates for different regional dialects over an area comprised of at least first and second distinct geographical regions, the method comprising:
-
analyzing speech in the first distinct geographical region using speech data characteristics representative of speech in the first distinct geographical region; detecting a change in position from the first distinct geographical region to the second geographical region; and analyzing speech in the second distinct geographical region using speech data characteristics representative of speech in the second distinct geographical region upon detecting that the aircraft has transitioned from the first distinct geographical region to the second distinct geographical region; wherein each distinct geographical region is characterized by a unique aircraft communication frequency, and further comprising; monitoring the aircraft communication frequency; detecting a new communication frequency when the aircraft transitions from the first distinct geographical region to the second distinct geographical region; and analyzing speech in the second distinct geographical region using the speech data characteristics representative of speech in the second distinct geographical region.

12. An aircraft speech recognition system that compensates for regional dialects over an area comprised of at least first and second distinct geographical regions, comprising:
-
a first source of speech data that represents a first acoustic model, a first phonetic dictionary, and a first language model in the aircraft speech recognition system that is characteristic of speech in the first distinct geographical region; a second source of speech data that represents a second acoustic model, a second phonetic dictionary, and a second language model in the aircraft speech recognition system that is characteristic of speech in the second distinct geographical region; and a processor coupled to the first source and to the second source and configured to process speech in the first distinct geographical region utilizing data in the first source, switch to the second source when the aircraft enters the second distinct geographical region, and process speech in the second distinct geographical region utilizing data in the second source. - View Dependent Claims (13, 14, 15, 16, 17, 18)
