An architecture for wavelet-packet based speech enhancement for hearing aids
Marı́a A. Trenas, Juan López, Emilio L. Zapata, Francisco Argüello · 2002
Wavelet packets have been applied in order to compensate the speech signal to improve the intelligibility for a common hearing impairment known as recruitment of loudness, a sensorineural hearing loss of cochlear origin. We present an architecture that allows selection of the best decomposition tree for each patient, in order to apply this wavelet-packet based parametric compression algorithm.
