Description
The human speech production system is reviewed through
general acoustic theory. Based upon that, the
characteristics of helium speech is compared to normal
speech. The Linear Prediction algorithm is derived
for computer implementation by recursive formulas.
The correction factors for the vocal tract area
functions are found from simulated helium speech and
normal speech data for four vowels. By the correction
factors, new corrected area functions are applied to
the Linear Prediction algorithm so that new synthesis
filters can be built. The output of the algorithm is
enhanced helium speech.
