Subword Unit Approaches for Retrieval by Voice

Abstract:

In this work, we describe a subword unit approach for information retrieval of items by voice. An algorithm based on the minimum description length (MDL) principle coverts an index written in terms of words with vocabulary size V into an index written in terms of phonetics subword units of size M much-less-than V. We demonstrate that, with this highly reduced vocabulary of subword units, improvement in ASR decode speed and memory footprint can be achieved, at the expense of a small drop in recall performance. Results on a music lyrics retrieval task are demonstrated.
