'''NETtalk''' is an [[artificial neural network]]. It is the result of research carried out in the mid-1980s by [[Terrence Sejnowski]] and Charles Rosenberg. The intent behind NETtalk was to construct simplified models that might shed light on the complexity of learning human level [[cognitive]] tasks, and their implementation as a [[connectionist]] model that could also learn to perform a comparable task. |

NETtalk was created to explore the mechanisms of learning to correctly pronounce English text. The authors note that learning to read involves a complex mechanism involving many parts of the human brain. NETtalk does not specifically model the image processing stages and letter recognition of the [[visual cortex]]. Rather, it assumes that the letters have been pre-classified and recognized, and these letter sequences comprising words are then shown to the [[neural network]] during training and during performance testing. It is NETtalk's task to learn proper associations between the correct pronunciation with a given sequence of letters based on the context in which the letters appear. In other words, NETtalk learns to use the letters around the currently pronounced [[phoneme]] that provide cues as to its intended phonemic mapping. |
