Today, I will be commenting on the TED Talk, "How do our brains process speech?" by educator Gareth Gaskell. This TED Talk focuses on how we identify and understand speech despite the speed and variability of speech.
Main Points:
- Humans know upwards of a thousand words and the word recognition in the human brain is almost as quick as humans generate speech, and it's incredibly accurate.
-
Speech signals are processed by rapidly matching sounds to words stored in the brain.
-
The human brain relies upon context to help differentiate ambiguous sound overlaps.
-
The brain can reconfigure sounds based on expectation and focus.
- "Yanny/Laurel", are ambiguous and they show how different factors influence perception.
-
Expectations and prior knowledge change the flexibility of the brain to interpret sounds.
-
We need sleep to solidify memories, and we're learning new vocabulary in our dreams.
-
We're superior to computers in comprehension because of the plasticity of our brains, and it's just so good at using context.
