On the effects of short-term spectrum smoothing in channel normalization
نویسندگان
چکیده
We present a simple analysis showing that channel normalization techniques are less eeective when applied to spectral energies obtained by (weighted) summation of components of the short-time Fourier power spectrum of speech. We show that applying channel normalization processing prior to critical band integration or linear predictive all-pole modeling improves the eeectiveness of the techniques.

Prediction of global sea cucumber capture production based on the exponential smoothing and ARIMA models
Sea cucumber catch has followed “boom-and-bust” patterns over the period of 60 years from 1950-2010, and sea cucumber fisheries have had important ecological, economic and societal roles. However, sea cucumber fisheries have not been explored systematically, especially in terms of catch change trends. Sea cucumbers are relatively sedentary species. An attempt was made to explore whether the tim...

متن کاملLog-Domain Circuits for Auditory Signal Processing
The theory and practice of log-domain filter design has reached the point where it is possible to incorporate log-domain filter structures into large current-mode VLSI systems. We report on interface circuits used to implement a current-mode frontend filterbank and feature extractor for acoustic pattern recognition. These circuits maintain a log-domain structure, acting on the unexpanded filter...
متن کاملEfficient Short-Term Electricity Load Forecasting Using Recurrent Neural Networks
Short term load forecasting (STLF) plays an important role in the economic and reliable operation ofpower systems. Electric load demand has a complex profile with many multivariable and nonlineardependencies. In this study, recurrent neural network (RNN) architecture is presented for STLF. Theproposed model is capable of forecasting next 24-hour load profile. The main feature in this networkis ...
