Query: Detection of speech events and speaker characteristics through
  photo-plethysmographic signal neural processing   The use of photoplethysmogram signal (PPG) for heart and sleep monitoring is
commonly found nowadays in smartphones and wrist wearables. Besides common
usages, it has been proposed and reported that person information can be
extracted from PPG for other uses, like biometry tasks. In this work, we
explore several end-to-end convolutional neural network architectures for
detection of human's characteristics such as gender or person identity. In
addition, we evaluate whether speech/non-speech events may be inferred from PPG
signal, where speech might translate in fluctuations into the pulse signal. The
obtained results are promising and clearly show the potential of fully
end-to-end topologies for automatic extraction of meaningful biomarkers, even
from a noisy signal sampled by a low-cost PPG sensor. The AUCs for best
architectures put forward PPG wave as biological discriminant, reaching $79\%$
and $89.0\%$, respectively for gender and person verification tasks.
Furthermore, speech detection experiments reporting AUCs around $69\%$
encourage us for further exploration about the feasibility of PPG for speech
processing tasks.
