KEYWORD TRAINING USING A SINGLE SPOKEN EXAMPLE FOR APPLICATIONS IN AUDIO DOCUMENT RETRIEVAL
Kate Knill and Steve Young
December 1994
An open keyword vocabulary word-spotting system is described for audio document retrieval. To model each keyword, an N-Best recogniser is used to hypothesise the keyword's phonetic transcription based on a single spoken example. The system is evaluated on a database of spoken messages and performance is found to be comparable with that obtained using pronunciations taken from a dictionary.
If you have difficulty viewing files that end '.gz',
which are gzip compressed, then you may be able to find
tools to uncompress them at the gzip
web site.
If you have difficulty viewing files that are in PostScript, (ending
'.ps' or '.ps.gz'), then you may be able to
find tools to view them at
the gsview
web site.
We have attempted to provide automatically generated PDF copies of documents for which only PostScript versions have previously been available. These are clearly marked in the database - due to the nature of the automatic conversion process, they are likely to be badly aliased when viewed at default resolution on screen by acroread.
