abstract = {IntroductionFew of us are skilled lipreaders while most
struggle with the task. Neural substrates that enable
comprehension of connected natural speech via lipreading are
not yet well understood.MethodsWe used a data-driven
approach to identify brain areas underlying the lipreading
of an 8-min narrative with participants whose lipreading
skills varied extensively (range $6–100\%,$
$mean = 50.7\%).$ The participants also listened to and
read the same narrative. The similarity between individual
participants’ brain activity during the whole narrative,
within and between conditions, was estimated by a voxel-wise
comparison of the Blood Oxygenation Level Dependent
(BOLD) signal time courses.ResultsInter-subject correlation
(ISC) of the time courses revealed that lipreading,
listening to, and reading the narrative were largely
supported by the same brain areas in the temporal, parietal
and frontal cortices, precuneus, and cerebellum.
Additionally, listening to and reading connected
naturalistic speech particularly activated higher-level
linguistic processing in the parietal and frontal cortices
more consistently than lipreading, probably paralleling the
limited understanding obtained via lip-reading. Importantly,
higher lipreading test score and subjective estimate of
comprehension of the lipread narrative was associated with
activity in the superior and middle temporal
cortex.ConclusionsOur new data illustrates that findings
from prior studies using well-controlled repetitive speech
stimuli and stimulus-driven data analyses are also valid for
naturalistic connected speech. Our results might suggest
an efficient use of brain areas dealing with phonological
processing in skilled lipreaders},
