Retrieving speech correctly despite the recognition errors

This work studies ways to recover from speech recognition errors in retrieving spoken documents. The methods are evaluated by Finnish news reading data using an unlimited vocabulary recognizer with language models for unsupervised morpheme-like units. Recognition errors can naturally be reduced by improving the recognizer, but the focus here is on the attempts to improve the search index more directly, namely by adding new index terms to replace those lost due to recognition errors.
