Using LicVox as the filter of separationalgorithm of power spectrum to be applied in high noiseenvironments, the UsiVox filters the user voice signals inorder to obtain the most promising sound before wordUsiVox recognition - processing and interpretation of voicesignal. The results showed that the proposed system andfilter recognizes the voice signal at 22KHz and classifies itbased on a grammar file to trigger a proposed action.Index Terms ⎯ Voice recognition.
