Original Kurzfassung:
Common temporal models for automatic chord
recognition model chord changes on a frame-wise basis. Due
to this fact, they are unable to capture musical knowledge
about chord progressions. In this paper, we propose a temporal
model that enables explicit modelling of chord changes and
durations. We then apply N-gram models and a neural-networkbased
acoustic model within this framework, and evaluate the
effect of model overconfidence. Our results show that model
overconfidence plays only a minor role (but target smoothing still
improves the acoustic model), and that stronger chord language
models do improve recognition results, however their effects are
small compared to other domains.
