In this post I describe Broca’s and Wernicke’s regions in speech production and propose that they work together to both recognize and produce speech.
The retina as implemented by Cortical IO roughly corresponds to Wernicke’s area. To bring this to the next level you need to add in Broca’s area. This is grammar or speech rules areas. It provides templates for utterances for both perceptions and production. The parts of speech are associated with the object/work store in Wernickes’s area and Broca’s area strings them together into stream of words.
The next thing for Cortical IO is to build up the word store with online learning. It’s offline SOM formation method is powerful but not how the brain does it.
Here is a delightful paper that shows work to capture the concepts in a biologically plausible model:
It is a spiking model but I think that the ideas could be implemented in other models. The model presented is the most comprehensive I have seen.
I’m sorry this answer is strung out over several posts and references. If there is any interest I may be able to combine them into a single post with a better explanations and pictures. If this is not helping anyone I have other things that need doing.
