abstract = {Evidence from experimental data has shown that users have difficulties in
properly remembering music and audio book titles according to categories such as
artist/author, afbum and title (metadata). When it comes to providing in-car search
for audio files it is therefore not sufficient to generate speakable ASR (Automatic
Speech Recognition) vocabulary from the original metadata only. Users are very
likely to come up with wording variants that might strongly deviate from the original
lexicon entry. In this paper we present an approach that enables the system to
retrieve audio files based on incomplete names. We pre-process audio file names,
applying filter and recombination rules. In order to verify in how far our preprocessed
metadata cover what users say when searching for audio files, we devised
and conducted an experiment to collect user speech data. Each subject had to go
through three different scenarios: completely unrestricted naming for music
selection, naming of individual favourite music according to given categories, and
recall and reproduction of given names and categories. In the latter case we provoked
cognitive overload by presenting audio file names in pairs of two for a short time
only. This fead the subjects to filter out crucial parts of the names presented, as we
intended. A first analysis of the speech data is supporting our approach: users often
address music by variants of the “official” name. Our first set of filter and
recombination rules, derived from introspection and common sense seems to cover a
majority of spoken variants guite well. A more fine-grained analysis of (he naming
data will increase this coverage. We present the experimental setup, our analysis of
the collected data and the results in more detail in the paper. We also give an outlook
on future working directions.},
