Inner speech captures the perception of external speech
Open accessAbstract
Talking silently to ourselves occupies much of our mental lives, yet the mechanisms underlying this experience remain unclear. The following experiments provide behavioral evidence that the auditory content of inner speech is provided by corollary discharge. Corollary discharge is the motor system's prediction of the sensory consequences of its actions. This prediction can bias perception of other sensations, pushing percepts to match with prediction. The two experiments below show this bias induced by inner speech, demonstrating that inner speech causes external sounds to be heard as similar to the imagined speech, and that this bias operates on subphonemic content.

Producing inner speech can have similar influences to overt speech on speech perception, such as priming perception of external sounds, suggesting that it too involves the sending of efference copies to receptive areas.
“Producing inner speech can have similar influences to overt speech on speech perception, such as priming perception of external sounds (e.g., Scott, Yeung, Gick, & Werker, 2013), suggesting that it too involves the sending of efference copies to receptive areas.”

Generating inner speech "captured" the perception of ambiguous auditory sounds, suggesting the functioning of a forward model in shaping the perception of an incoming sensation.
“In two experiments, Scott, Yeung, Gick, and Werker (2013) showed that generating inner speech “captured” the perception of ambiguous auditory sounds, suggesting the functioning of a forward model in shaping the perception of an incoming sensation, both when the vocalization was generated in inner speech and when it was silently mouthed (see Hubbard & Stoeckig, 1988, for a similar example of”

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.
