Claim Text:
1. A method for determining speech level, said method including steps of: (a) performing voice detection on an audio signal to identify at least one voice segment of the audio signal; (b) for each said voice segment, determining a parametric spectral model of content of each frequency band of a set of perceptual frequency bands of the voice segment; (c) for said each frequency band of each said voice segment, generating data indicative of a corrected estimated speech level, including by correcting an estimated speech level determined by the model for the frequency band using a predetermined characteristic of reference speech; and (d) generating a speech level signal in response to the data generated in step (c), wherein the speech level signal is indicative, for each said voice segment, of a level of speech indicated by the voice segment.
