<p>A method for utilizing validity constraints in a speech endpoint detector (414) comprises a validity manager (430) that may utlize a pulse width module (1310) to validate utterances that include a plurality of energy pulses during a certain time period. The validity manager (430) also may utilize a minimum power module (1312) to ensure that speech energy below a predetermined level is not classified as a valid utterance. In addition the validity manager (430) may use a duration module (1314) to ensure that valid utterances fall within a specified duration. Finally, the validity manager (430) may utilize a short-utterance minimum power module (1316) to specifically distinguish an utterance of short duration form background noise based on the energy level of the short utterance.</p> |
