CONCLUSIONS
Acoustic-phonetic mapping helps to address
linguistically relevant information in the speech
signal, ignoring extra-linguistic sources of
variation. The advantages of mapping are
reflected in the two measures which we have
presented

• ACIS shows that mapping leads to better consonant
  identification rates for all except a few of the
  language-specific consonants. The improvement can
  be put down to the systems ability to map
  acoustically variable consonant realisations to
  more homogeneous phonetic feature vectors.

reflected in the two measures which we have
presented

• APMS shows that the confusions which occur in the
  mapping experiment are less severe than in the
  baseline experiment from a phonetic point of
  view. There are fewer confusions on the phonetic
  dimensions manner, place and voicing when mapping
  is applied, because the system focuses on
  distinctive information in the acoustic signals.

SUMMARY
Acoustic-phonetic mapping leads to fewer and
phonetically less severe consonant confusions.
