Adaptive vehicle state-based hands-free phone noise reduction with learning capability

摘要

This disclosure generally relates to a system, apparatus and method for achieving an adaptive vehicle state based handsfree noise reduction feature. Provided is a noise reduction tool for adaptively applying a noise reduction strategy to a sound input that uses feedback voice quality measures and machine learning to develop future noise reduction strategies, wherein the noise reduction strategies include analyzing vehicle operating state information and external information predicted to be related to the passenger compartment Noise and selecting noise reduction prefilter options based on the analysis.
