open vocabulary speech recognition with flat hybrid models

... automatic speech recognition systems operate with a large but limited vocabulary, finding the most likely words in the vocabulary for the given acoustic signal. While large vocabulary continuous speech recognition ... performance of a hybrid sys- tem with baseline units 9 (§5.2) and one with units learned by our model on OOV detection and phone error rate. We present results using a hybrid system with 5k and 10k ... objective is to produce a lexicon of sub-word units that can be used by a hybrid sys- tem for open vocabulary speech recognition. Rather than relying on the text alone, we also utilize side information:...
