Line Spectral Frequency-based Noise Suppression for Speech-Centric Interface of Smart Devices

Line Spectral Frequency-based Noise Suppression for Speech-Centric Interface of Smart Devices

This paper proposes a noise suppression technique for speech-centric interface of various smart devices. The proposed method estimates noise spectral magnitudes from line spectral frequencies (LSFs), using the observation that adjacent LSFs correspond to peak frequencies of spectrum, whereas isola...
