Abstract
A computer implemented voice recognition method and system for adjusting an input level to adjust the input signal amplitude level of spoken words to enhance voice recognition. A user is prompted with a word to speak into a microphone. The spoken word is converted into an analog electrical signal having an input signal amplitude level. A sound card then converts this analog signal to a digital stream of data. This input signal amplitude level is compared to a reference amplitude level. An adjustment to an input volume control is made with respect to the comparison to adjust the input signal amplitude level to approach the reference amplitude level. The invention also uses an iterative process for a set number of iterations to make the adjustment for the input signal amplitude level to approach the reference amplitude level.
