You may think that we make no drastic change to speech sounds we get through the ear.
In truth, the brain controls the amount of information within reasonable limits.
Two researchers recorded spontaneous conversation without the participants' knowledge.
The tape recording was then cut up into recordings of individual words.
These individual word recordings were played to people who were asked to identify what they heard.
Surprisingly, played in isolation, only about half of the words were identifiable.
Yet, when we are listening to continuous speech, we do not have the impression that we are guessing and filling in gaps.
The speech sounds clear.
If the tape recordings are cut up into larger and larger parts, then the comprehensibility of the speech increases.
The normal Clarity of speech is an illusion.
The brain imposes an interpretation upon the speech that it hears and constructs hypotheses about the general context and meaning, which enables the interpretation of much of the input.
So, when two people claim that they heard a speaker say something slightly different, it may be that both are accurate.
Each of them may have heard, in terms of a higher-level interpretation by the brain, a different sentence.
The perception of speech may sometimes be a rather automatic process.
We may not be aware that we are monitoring conversations in which we are not taking part.
At a party you may be able to identify your own name in a conversation across the room despite apparent unawareness of the content of the rest of the conversation.
In order to recognize that your name was spoken, the brain must have been monitoring the progress and speech pattern of the conversation which was taking place elsewhere, even though you did not notice yourself doing this.
It appears that we can have the capacity to monitor more than one chain of speech at once, though it may not be possible for us to monitor both to the same degree, or for us to have full conscious awareness of the content of both.
We are also able to attend selectively to one conversation, even if there are loud competing conversations in the background, by Extracting the relevant information from the complex signal of mixed speech.
This is referred to as the cocktail party phenomenon.
お礼
audibleは可聴ではなく、測定可能だったんですね。そこがずっと引っかかっていたんです。ありがとうございます！
