Single channel AI speech reverberation time modification for room dimension matching

<p dir="ltr">Reverberation is caused by room impulse reflection from walls, ceilings and other plane surfaces contributing an additive echo proportional to the geometry of the environment. Reverberation in speech plays a role in interpretation, giving listeners a sense of the size, shape and materials of the room. In an immersive VR/AR scenario where a speaker is presented in a different virtual environment to their actual environment, a mismatch between the recording and purported room geometries causes psychoacoustic dissonance. This paper presents an AI-based algorithm to estimate and remove room reverberation impulse effects from speech recorded in a source environment, and add reverberation modeled on the target environment. Effectiveness is measured via psychoacoustic assessment.</p>
