DRC 1.2.1

Simulates the DRC model for explaining text to speech conversion

The DRC model is a computational model of reading which is intended to explain how skilled readers perform certain basic reading tasks. The acronym emphasizes the two fundamental properties of the model: it is a Dual Route model, and within the model information processing occurs in a Cascaded fashion.

The model consists of three routes, the lexical semantic route, the lexical nonsemantic route, and the GPC route. Each route is composed of a number of interacting layers. These layers contain sets of units. The units represent the smallest individual symbolic parts of the model, such as words in the orthographic lexicon or letters in the letter unit layer.

There are two ways in which the units of different layers interact. One is through inhibition, where the activation of a unit makes it more difficult for the activation of other units to rise. The other is through excitation, where the activation of a unit contributes to the activation of other units. Units may also interact on the same level through lateral inhibition.
