摘要
Features are disclosed for estimating reverberation an audio signal without prior knowledge of the sound captured in the audio signal and without prior knowledge of the environment in which the sound was captured. This reverberation estimation may be referred to as “blind estimation.” The reverberation may be blindly estimated using autocorrelation of the sound intensity of the signal with respect to time. The blind estimation can be used to decide whether or not to mitigate the effects of reverberation in the signal prior to performing subsequent processes, such as automatic speech recognition.
