Abstract

During the past three decades, the issue of processing spectral phase has been largely neglected in speech applications.
There is no doubt that the interest of speech processing community towards the use of phase information in a big
spectrum of speech technologies, from automatic speech and speaker recognition to speech synthesis, from speech
enhancement and source separation to speech coding, is constantly increasing. In this paper, we elaborate on why
phase was believed to be unimportant in each application. We provide an overview of advancements in phase-aware
signal processing with applications to speech, showing that considering phase-aware speech processing can be bene-
ficial in many cases, while it can complement the possible solutions that magnitude-only methods suggest. Our goal
is to show that phase-aware signal processing is an important emerging field with high potential in the current speech
communication applications. The paper provides an extended and up-to-date bibliography on the topic of phase aware
speech processing aiming at providing the necessary background to the interested readers for following the recent advancements
in the area. Our review expands the step initiated by our organized special session and exemplifies the
usefulness of spectral phase information in a wide range of speech processing applications. Finally, the overview will
provide some future work directions.
