Abstract
Recent advancements in computer science in general and
speech processing technology in particular provide the opportunity to
transform speech as a means of communication into a novel measurement tool which can be utilized to address many problems in various
fields. In this paper we investigate two experiments which use speech as
their metric to demonstrate new approaches to two problematic in the
field of cognition. The first study utilizes speech as mean of assessment of
cognitive decline in elderly and the second study use it as a measurement
tool for cognitive load and speech time pressure. After describing these
two approaches and their respective results separately, we compare them
and discuss their advantages as well as their drawbacks.
