The part of brain responsible for speech processing found: Study
This is going to be an important discovery and is already being discussed on science forums across the world. A latest study claims that scientists have been able to discover the exact region of the brain that is sensitive to the timing of speech. The study claims that it is this part of the brain that is critical in human language.
Experts who were involved in this critical study claim that in order to understand what others is saying, your brain needs to interpret different time signatures. This makes timing so much important in human speech and proper conversation.
Experts who were involved in the study are of the opinion that some of the measurements are phonemes that are the shortest unit of speech and it last for between 30 and 60 milliseconds. Another measure is syllable which usually lasts for between 200 and 300 milliseconds and whole words are even longer.
Study claims that in order to deal with this information the auditory system will sample information in chunks that are equivalent to average consonant or syllable. For the study, researchers have tried to do the same and cut recordings of foreign speech in chunks ranging between 30 and 660 milliseconds in length. These chunks are reassembled using a new algorithm that creates speech quilts.
It is needless to say that scientists involved in the study are excited. Tobias Overath, an assistant research professor of psychology and neuroscience at Duke says, â€œThat was pretty exciting. We knew we were onto somethingâ€¦ Overath said, â€œWe really went to great lengths to be certain that the effect we were seeing in STS was due to speech-specific processing and not due to some other explanation, for example, pitch in the sound or it being a natural sound as opposed to some computer-generated sound.â€
