Demonstration of single channel speech dereverberation
I made a recording of my voice with a
monoral voice recorder and tried a dereverberation. During the
recording, voice recorder was held
with my hand and kept relatively still.

contains recorded speech.

contains dereverberated speech processed by the "multi-step
linear prediction based dereverberation". (Ephraim's spectral
subtraction was employed as a pre-processing to suppress
