How do our Brains Process Speech

The typical 15 years old knows between 25,000 and 50,000 different words. By age 55, that number averages between 32,000 and 58,000. Spoken aloud, most of those words last but a second. So with every word, the Brain features a fast decision to make: which of those thousands of options matches the signal? About 98% of the time, the brain chooses the right word. But how?

Speech comprehension is different from reading comprehension, but it’s almost like signing comprehension— through vocable recognition has been studied quite signing. The key to our ability to know the speech is that the brain’s role as a parallel processor means that it can do multiple things at an equivalent time. 

Most theories assume that every word we all know is represented by a separate processing unit that has only one job: to assess the likelihood of incoming speech matching that specific word. Within the brain's context, the processing unit that represents a word is probably going a pattern of firing activity across a gaggle of neurons within the brain’s cortex. once we hear the start of a word, several thousand such units may become active, because, with just the start of a word, there are many possible matches. 

Then, because the word goes on, more and more units register that some vital piece of data is missing and lose activity. Possibly well before the top of the word, only one firing pattern remains active, like one word. this is often called the "recognition point." within the process of honing in on one word, the active units suppress the activity of others, saving vital milliseconds. most people can comprehend up to about 8 syllables per second. Yet, the goal isn't only to acknowledge the word but also to access its stored meaning.

The brain accesses many possible meanings at an equivalent time before the word has been fully identified. we all know this from studies that show that even upon hearing a word fragment— like "cap"— listeners will start to register multiple possible meanings, like captain or capital, before the complete word emerges. this means that each time we hear a word there’s a quick explosion of meanings in our minds, and by the popularity point, the brain has settled on one interpretation. the popularity process moves sooner with a sentence that provides us context than during a random string of words.

Context also helps guide us towards the intended meaning of words with multiple interpretations, like "bat," or "crane," or in cases of homophones like "no" or "know." For multilingual people, the language they're taking note of is another cue, wont to eliminate potential words that don’t match the language context. So, what about adding completely new words to the present system? whilst adults, we may encounter a replacement word every few days. 

But if every word is represented as a fine-tuned pattern of activity distributed over many neurons, how can we prevent new words from overwriting old ones? we expect that to avoid this problem, new words are initially stored during a part of the brain called the hippocampus, well far away from the most store of words within the cortex, so that they don’t share neurons with other words. Then, over multiple nights of sleep, the new words gradually transfer over and interweave with old ones. 


Researchers think this gradual acquisition process helps avoid disrupting existing words. So within the daytime, unconscious activity generates explosions of meaning as we chat away. At night, we rest, but our brains are busy integrating new knowledge into the word network. once we awaken, this process ensures that we’re ready for the ever-changing world of language.
