COur brains have an“auto-correct'”feature that we use when re-interpreting(重新解释)ambiguous sounds,according to new research.The study sheds light on how the brain usesinformation gathered after the discovering of an initial sound to aid speech comprehension.Thefindings point to new ways we use information and context to aid in speech comprehension"What a person thinks they hear does not always match the actual signals that reach theear,"explains lead author Laura Gwilliams."This is because the brain re-evaluates theinterpretation of a speech sound at the moment each following speech sound is heard in orderto update interpretations as necessary,"Gwilliams says.It's well known that the perception of a speech sound is determined by its surroundingcontext-in the form of words,sentences and other speech sounds.This plays out in everydaylife-when we talk,the actual speech we produce is often ambiguous.For example,when afriend says she has a“dent(凹a)”in her car,,you may hear“tent'.Although this kind ofambiguity happens regularly,we.as listeners,are hardly aware of it."This is because the brainautomatically resolves the ambiguity for us-it picks an interpretation and that's what weperceive to hear,"explains Gwilliams."The way the brain does this is by using the surroundingcontext to narrow down the possibilities of what the speaker may mean."In the study,the researchers sought to understand how the brain uses this followinginformation to adjust our perception of what we initially heard.To do this,they conducted aseries of experiments in which the subjects listened to isolated syllables and similarly soundingwords.Their results produced three primary findings:The brain's primary auditory cortexis sensitive to how ambiguous a speech sound is at just 50 milliseconds after thesound's appearance.The brain "replays"previous speech sounds while interpreting thefollowing ones,suggesting re-evaluation as the rest of the word unfolds.The brain makescommitments to its"best guess"of how to interpret the signal after about half a second.28.What is the study mainly about?A.Why people make unclear sounds.B.How brains understand unclear wordsC How brains tell apart useful information.D.Why some people process information faster.29.What does the author want to show by giving the example in paragraph 3?A It is normal for people to make unclear sounds.B.People are more likely to mishear their friends.C.People can understand others even if they mishear a word.D.People are likely to mistake a word for something familiar.30.What do we know about the unclear words in the experiments?A.They seemed to be useless.B.They were noticed instantlyC.They led to misunderstanding.D.They stopped us thinking further.31.What does the underlined part"the signal"in the last paragraph refer to?A.The previous speech sound.B.The similarly sounding word.C.The unclearly sounding word.D.The following speech sound.
