Patent ID: 8280618

Claim:
A method for providing information relating to taxiing an aircraft at an airport having a plurality of taxi paths, the method comprising: identifying, by a processing system, a first aircraft location on a first taxi path of the plurality of taxi paths; identifying, by the processing system, a first aircraft heading at the first aircraft location; determining, by the processing system, a first subset of possible taxi paths for selection from the plurality of taxi paths based on the first aircraft location and the first aircraft heading, wherein each respective taxi path of the first subset intersects the first taxi path in the first aircraft heading from the first aircraft location; limiting, by the processing system, a speech recognition vocabulary using the first subset, resulting in a limited speech recognition vocabulary, wherein each taxi path in the limited speech recognition vocabulary intersects the first taxi path in the first aircraft heading from the first aircraft location; receiving an audio input; recognizing, by the processing system, the audio input as a second taxi path of the first subset using the limited speech recognition vocabulary; and providing indication of the second taxi path in response to recognizing the audio input as the second taxi path.
