Abstract
Human speech is detected in an audio signal by first providing a single autocorrelated signal indicative of the audio signal multiplied by a time-delayed portion of the audio signal, the delay being an amount of time indicative of a period corresponding to a first formant frequency. Portions of the autocorrelated signal are compared with a scaled noise value. Human speech is detected by examining whether a plurality of portions of the autocorrelated signal exceed the scaled noise value.
