Abstract

Sine wave replicas of spoken words can be perceived both as nonphonetic auditory forms and as words, depending on a listener's experience. In this study, brain areas activated by sine wave words were studied with fMRI in two conditions: when subjects perceived the sounds spontaneously as nonphonetic auditory forms ("nïve condition") and after instruction and brief practice attending to their phonetic attributes ("informed condition"). The test items were composed such that half replicated natural words ("phonetic items") and the other half did not, because the tone analogs of the first and third formants had been temporally reversed ("nonphonetic items"). Subjects were asked to decide whether an isolated tone analog of the second formant (T2) presented before the sine wave word (T1234) was included in it. Experience in attending to the phonetic properties of the sinusoids interfered with this auditory matching task and was accompanied by a decrease in auditory cortex activation with word replicas but not with the acoustically matched nonphonetic items. Because the activation patterns elicited by equivalent acoustic test items depended on a listener's awareness of their phonetic potential, this indicates that the analysis of speech sounds in the auditory cortex is distinct from the simple resolution of auditory form, and is not a mere consequence of acoustic complexity. Because arbitrary acoustic patterns did not evoke the response observed for phonetic patterns, these findings suggest that the perception of speech is contingent on the presence of familiar patterns of spectral variation. The results are consistent with a short-term functional reorganization of auditory analysis induced by phonetic experience with sine wave replicas and contingent on the dynamic acoustic structure of speech.

  • Activation in the left posterior temporal gyrus/sulcus increases when sine wave analogues of speech are recognised as speech relative to when the same stimuli are not recognised as speech.

    “Further evidence that these speech selective responses relate to familiarity with the patterns of spectral variation (Liebenthal et al., 2003) came from two studies that showed activation in the left posterior temporal gyrus/sulcus increased when sine wave analogues of speech were recognised as speech relative to when the same stimuli were not recognised as speech (Dehaene-Lambertz et al., 2005;”

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.
