Neural mechanisms underlying auditory feedback control of speech
Open accessAbstract
The neural substrates underlying auditory feedback control of speech were investigated using a combination of functional magnetic resonance imaging (fMRI) and computational modeling. Neural responses were measured while subjects spoke monosyllabic words under two conditions: (i) normal auditory feedback of their speech and (ii) auditory feedback in which the first formant frequency of their speech was unexpectedly shifted in real time. Acoustic measurements showed compensation to the shift within approximately 136 ms of onset. Neuroimaging revealed increased activity in bilateral superior temporal cortex during shifted feedback, indicative of neurons coding mismatches between expected and actual auditory signals, as well as right prefrontal and Rolandic cortical activity. Structural equation modeling revealed increased influence of bilateral auditory cortical areas on right frontal areas during shifted speech, indicating that projections from auditory error cells in posterior superior temporal cortex to motor correction cells in right frontal cortex mediate auditory feedback control of speech.

Activation in right prefrontal cortex and rolandic cortical activity increases with bilateral superior temporal activation during distorted feedback.
“Fourth, activation in the right prefrontal cortex and rolandic cortical activity increased with bilateral superior temporal activation during distorted feedback (Tourville et al., 2008) which suggested a role for these areas in modulating subsequent speech output, or in resolving interference.”

Suppression of auditory processing is proportional to quality of feedback; superior temporal activation increases when speech is distorted or auditory feedback is delayed.
“This suppression of auditory processing was proportional to the quality of the feedback; consequently, superior temporal activation increased when speech was distorted (Christoffels et al., 2007; Tourville et al., 2008; Christofells et al., 2011; Zheng et al., 2010) or when auditory feedback was delayed (Takaso et al., 2010).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
