Abstract
Statistical Language Models are often difficult to derive because of the so-called “dimensionality curse”. Connectionist Language Models defeat this problem by utilizing a distributed word representation which is modified simultaneously as the neural network synaptic weights. This work describes certain improvements in the utilization of Connectionist Language Models for single-pass real-time speech recognition. These include comparing the word probabilities independently between the words and a novel mechanism of factorization of the lexical tree. Experiments comparing the improved model to the standard Connectionist Language Model in a Large-Vocabulary Continuous Speech Recognition (LVCSR) task show the new method obtains about a 33-fold speed increase while achieving a minimally worse word-level speech recognition performance.
