System for suppressing passing tire hiss
First Claim
Patent Images
1. A passing tire hiss noise attenuation system, comprising:
- a noise detector configured to compare an input signal to a passing tire hiss model and identify whether a noise in the input signal is passing tire hiss; and
a noise attenuator coupled with the noise detector and configured to attenuate at least a portion of the identified passing tire hiss from the input signal to generate an output signal with reduced passing tire hiss noise.

Abstract
A voice enhancement logic improves the perceptual quality of a processed voice. The voice enhancement system includes a passing tire hiss noise detector and a passing tire hiss noise attenuator. The passing tire hiss noise detector detects a passing tire hiss noise by modeling the passing tire hiss. The passing tire hiss noise attenuator dampens the passing tire hiss noise to improve the intelligibility of a speech signal.

10. A method of attenuating passing tire hiss noise, comprising:
-
receiving an input signal; identifying, by a noise detector that comprises a processor configured to run logic to detect passing tire hiss, whether a noise in the input signal is passing tire hiss based on a comparison between the input signal and a passing tire hiss model; and attenuating at least a portion of the identified passing tire hiss from the input signal to generate an output signal with reduced passing tire hiss noise. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A non-transitory computer-readable medium with instructions stored thereon, where the instructions are executable by a processor to cause the processor to perform the steps of:
-
comparing an input signal to a passing tire hiss model; identifying whether a noise in the input signal is passing tire hiss based on the comparison between the input signal and the passing tire hiss model; and attenuating at least a portion of the identified passing tire hiss from the input signal to generate an output signal with reduced passing tire hiss noise. - View Dependent Claims (19, 20)
