Abstract :
At mode changing operation of car´s air-conditioner, we have a fricative problem. We´re inspecting all products using headphone by persons. Our goal is to invent an automated fricative inspection system. We report the wavelet technology with (1) spike-noise-cut filter, (2) superposition filter, and (3) features extract with image processing. As the result, we can carry out to inspect fricative in factory noise circumstance.
