Speech recognition is an active process that involves some form incontri coding predictive coding. This statement is relatively uncontroversial. What is less clear is the source of the prediction. The dual-stream model of speech processing suggests that there are two possible sources of predictive coding in speech perception: Here I provide an overview of the dual-stream model of speech processing and then discuss evidence concerning the source of predictive coding during speech recognition. I conclude that, in contrast to recent theoretical trends, the dorsal sensory-motor stream is not a source of forward prediction that can facilitate speech recognition. Rather, it is forward prediction coming out of the ventral stream that serves this function. Readers will 1 be able to explain the dual route model of siti incontri gratu processing including the function of the dorsal and ventral streams in language processing, 2 understand how disruptions to certain components of the dorsal stream can cause conduction aphasia, incontri coding be able to explain the fundamental principles of state feedback control in motor behavior, and 4 understand the role of predictive coding in motor control and in perception and how predictive coding coming out of the two streams may have different functional consequences. The dual route model of the organization of speech processing is grounded in the fact that the brain has to do two incontri coding of things with acoustic speech information. On the one hand, acoustic speech input must be linked to conceptual-semantic representations; that is, speech must be understood. On the other hand, the brain must to link acoustic speech information to the motor speech system; that is, speech sounds must be reproduced with the vocal tract. These are different computational tasks. The endpoint representations are radically different; therefore the set of computations in the two types of transformations must be different. The neural pathways involved must also, therefore, be non-identical.Digital Read Serial

Cortical processing of complex sounds. I suggested here that it might also be fruitful to consider the notion of forward prediction in the context of a dual stream model; specifically that the dorsal and ventral streams represent two sources of forward prediction.
