Claim:
A method of automatic speech recognition, comprising the steps of: a) prompting a user to input speech; b) after step a), initiating a listening period to monitor audio via a microphone, such that there is no pause between the end of step a) and the beginning of step b); and then c) communicating a begin-speaking audible indicator to the user during the listening period; d) receiving, via the microphone, signals corresponding to input speech from the user and signals corresponding to the begin-speaking audible indicator; and e) determining if the input speech was prematurely enunciated; f) applying a digital filter to filter out signals corresponding to the begin-speaking audible indicator, if it is determined in step e) that the user's input speech was prematurely enunciated; g) estimating speech energies inadvertently filtered from the speech; and h) appending the identified speech energies to the received speech signals.
