Claim:
1. In a multimedia rendering environment, a method for rendering audio information comprising: differentiating voice components from non-voice components by separating center channel and mono information from left, right and surround channels in a stream of audio information; detecting the voice component by computing monaural information from information common to both the left and right channels; identifying the non-voice component from left surround, right surround and subwoofer channels in the audio stream; attenuating right and left components in the stream of audio information in response to the detected voice component in the audio stream by attenuating the non-voice components, and boosting the voice component in the audio stream up toward a voice threshold level based on attenuation of the right and left components, the voice threshold level being greater than a non-voice threshold level; and rendering the boosted voice component and the attenuated components simultaneously for improving audibility of speech sounds in the audio stream.
