COUNTERMEASURES FOR VOICE RECOGNITION DETERIORATION DUE TO EXTERIOR NOISE FROM PASSING VEHICLES

摘要

Mitigating disruption to a voice recognition system in a vehicle caused by a passing source of noise is provided. Sensors sense an approaching truck or the like that is likely to disrupt operation of the in-vehicle voice recognition system. Countermeasures are initiated to mitigate the disruption.

1. A system for countering disruption to a voice recognition system in a vehicle caused by a source of noise in proximity to the vehicle, comprising:
an in-vehicle microphone that obtains a voice signal for input to the voice recognition system; a plurality of sensors each operative to sense a condition external to the vehicle; a tangible data processor coupled to the sensors and in data communication with a memory on which is stored instructions which when executed on the processor implement a noise analyzer operative, based on the sensed conditions, to:
identify a source of noise external to the vehicle and approaching the vehicle;determine a likelihood that the noise source will disrupt operation of the voice recognition system; andestimate an amount of time remaining before the disruption is likely to begin; and means for instantiating a countermeasure to the disruption based on the noise source identity, the likelihood of the disruption, and the estimated time remaining.
