Helium Speech Investigations.
Abstract
The basic objective of the work is to continue evaluations of and achieve further improvements in the Singer-Kearfott unscrambler technique. Investigations have shown that improvements result from using single polarity rather than bipolar pitch sync detection, and from excluding input signal components above 10 KHz. Simple compensation of the non-linear formant shift, and modification of the glottal wave decay rate produced no apparent improvement. A comparative evaluation of performance at the University of Florida was completed. (Author)
