Personalized Dereverberation of Speech

Supplementary Material

Video Demonstration

In this video we demonstrate the one-time personalization process introduced in the paper. We measure the representative room impulse response (rRIR) and then capture a few minutes of speech. Following personalization, we show an online conversation between a male and a female in two different environments. Our processing achieves both dereverberation and denoising resulting in better speech clarity.

Dereverberation Comparison

Methods Blind ML Male 1 Female 1 Male 2 Female 2 Comments
Recorded - -

Real recordings of speech by a male and a female in different environments.

Wiener ✘ ✘

Wiener struggles at dereverberation and creates strong artifacts due to imprecise RIR.

WPE ✔ ✘

WPE produces fewer artifacts, but achieves minimal dereverberation.

Demucs ✔ ✔

Demucs is designed primarily for audio denoising. When trained with reverberation data, it fails to handle complex RIRs.

Demucs
(pretrained)
✔ ✔

Pre-trained Demucs results in denoising but minimal dereverberation.

HiFi-GAN ✔ ✔

HiFi-GAN, trained on our data, produces inadequate dereverberation and clarity of speech.

HiFi-GAN
(pretrained)
✔ ✔

Pre-trained HiFi-GAN produces inadequate dereverberation and clarity of speech as well.

Audition
(100% Dereverb)
✔ ✔

Adobe Audition produces some dereverberation but distorts the audio.

Ours ✘ ✔

Our method produces results almost indistinguishable from clean recordings.

Clean - -

Reference speech recorded using a lavalier microphone worn by the user.
