23. A method for generating a transition signal as in claim 22 wherein said method further comprises the step of selectively weighting said power levels of said acoustic parameter signal to accurately represent the phonemic information in said voice signal.
22. A method for generating a transition signal as in claim 21, wherein a bias is applied to each said average power level and each said power level prior to calculating the logarithms thereof, whereby the influence on said first difference levels of extraneous noise during silences in the voice signal is minimized.
