Abstract
The work is on OOV detection in LVCSR using neural networks
Annotation
Confidence measures and classifying techniques are widely used for the recognition error detection task in LVCSR (Large Vocabulary Continuous Speech Recognition). But in many recognition scenarios the amount of words not included in the dictionary (e.g. real names, neologisms) lead to so-called OOV (Out Of Vocabulary) errors which increase the WER (Word Error Rate) even more. The hereby described work acknowledges and investigates further improvements of an OOV detection task performed by combining strong and weak phone posterior features using neural networks based on [ICASSP08] and the use of phone context.
