Abstract

Knowledge about the reverberation time (T60) is exploited by numerous algorithms, e.g., for automatic speech recognition, speech dereverberation, or as a feature for acoustic scene classification. This contribution provides a comprehensive survey about various state-of-the-art methods to estimate the reverberation time blindly from a noisy and reverberant speech signal and compares their estimation performance for different acoustic scenarios. The evaluation considers different acoustic conditions regarding the signal-to-noise ratio (SNR), direct-to-reverberation ratio (DRR) and T60, and uses databases with room impulse responses measured in different acoustic enclosures. The findings of the Acoustic Characterisation of Environments (ACE) Challenge are extended by taking into account algorithms and acoustic scenarios which are not considered in this benchmarking campaign, and by using a much larger set of reverberant speech signals.
