Query: Detection of Glottal Closure Instants from Raw Speech using
  Convolutional Neural Networks   Glottal Closure Instants (GCIs) correspond to the temporal locations of
significant excitation to the vocal tract occurring during the production of
voiced speech. GCI detection from speech signals is a well-studied problem
given its importance in speech processing. Most of the existing approaches for
GCI detection adopt a two-stage approach (i) Transformation of speech signal
into a representative signal where GCIs are localized better, (ii) extraction
of GCIs using the representative signal obtained in first stage. The former
stage is accomplished using signal processing techniques based on the
principles of speech production and the latter with heuristic-algorithms such
as dynamic-programming and peak-picking. These methods are thus task-specific
and rely on the methods used for representative signal extraction. However, in
this paper, we formulate the GCI detection problem from a representation
learning perspective where appropriate representation is implicitly learned
from the raw-speech data samples. Specifically, GCI detection is cast as a
supervised multi-task learning problem solved using a deep convolutional neural
network jointly optimizing a classification and regression cost. The learning
capability is demonstrated with several experiments on standard datasets. The
results compare well with the state-of-the-art algorithms while performing
better in the case of presence of real-world non-stationary noise.
