Reverberation time estimation based on a model for the power spectral density of reverberant speech [pdf]Paper  doi  abstract   bibtex   
In this paper, it is shown that the Power Spectral Density (PSD) of late reverberant speech can be described by a first-order Infinite Impulse Response (IIR) model with the pole related to the reverberation time. Utilizing this first-order IIR model, an online method for reverberation time estimation (RTE) from a recorded reverberant signal is proposed. The proposed method takes advantage of processing in subband domain in order to reliably estimate the reverberation time in noisy environments. Comparing with a well-known maximum likelihood approach for RTE, the superior performance of the new approach for fast tracking of RT with higher accuracy is demonstrated.
