Acoustic-phonetic information from excitation source for refining manner hypotheses of a phone recognizer
Reliable acoustic-phonetic (AP) information derived from the speech signal can be used to detect and correct errors in the output of a phone recognizer. In this paper, limited aco...

Impact of the correlation between forward and backscatter channels on RFID system performance
The channel of radio frequency identi cation (RFID) can be modeled as a cascaded channel consisting of a forward link and a backscatter link. The correlation between the forward a...

Concurrent estimation of singing voice F0 and phonemes by using spectral envelopes estimated from polyphonic music
The scarcity of available multi-track recordings constitutes a severe constraint on the training of probabilistic models for voice extraction from polyphonic music. We propose a n...

ON the recovery of time-varying spectral envelope information from AQHM-derived spectra
Spectral envelopes of speech signals are typically obtained by making stationarity assumptions about the signal which are not always valid. The Adaptive Quasi-Harmonic Model (AQHM...

Seam merging for image resizing with structure preservation
In image resizing process, preserving structure on an image is important to produce plausible results. We proposed seam merging, a seam-carving-based image resizing method, and a ...
