Patent
System for Suppressing Wind Noise
TL;DR: In this paper, a voice enhancement system includes a noise detector and a noise attenuator, which detects a wind buffet and a continuous noise by modeling the wind buffet to improve the intelligibility of an unvoiced, a fully voiced or a mixed voice segment.
Patent
Bandwidth extension of narrowband speech
TL;DR: In this article, a high-band generator that generates a high frequency spectrum based on a narrowband spectrum was used to extend the bandwidth of a speech signal into a wideband spectrum.
Patent
High frequency compression integration
TL;DR: A speech enhancement system that improves the intelligibility and the perceived quality of processed speech includes a frequency transformer and a spectral compressor as mentioned in this paper, which converts speech signals from the time domain to the frequency domain.
Patent
System for improving speech intelligibility through high frequency compression
TL;DR: In this article, a speech enhancement system that improves the intelligibility and the perceived quality of processed speech includes a frequency transformer and a spectral compressor, which converts speech signals from the time domain to the frequency domain.
Patent
Speech enhancement through partial speech reconstruction
TL;DR: In this article, a low-frequency reconstruction controller is used to select a predetermined portion of a time domain signal and a harmonic generator generates low frequency harmonics in the time domain that lie within a frequency range controlled by a background noise model.
