Reverberation-robust speech recognition has become important in the field of distant-talking speech recognition. However, as no common reverberation criteria for the recognition of reverberant speech have yet been proposed, it has been difficult to estimate its effectiveness. We propose new reverberation criteria RSR-Dn (Reverberant Speech Recognition criteria with Dn) based on ISO3382 acoustic parameters. We first designed the criteria using the relationship between speech recognition performance and ISO3382 acoustic parameters. We then estimated the speech recognition performance obtained with the criteria. Evaluation experiments confirmed that the recognition performance can be accurately and robustly estimated with our proposed criterion.
