Abstract

Finite impulse response (FIR) Wiener-like filters are applied to time trajectories of the cubic-root compressed short-term power spectrum of noisy speech recorded over cellular telephone communications. Informal listenings indicate that the technique brings a noticeable improvement to the quality of processed noisy speech while not causing any significant degradation to clean speech. Alternative filter structures are being investigated as well as other potential applications in cellular channel compensation and narrowband to wideband speech mapping
