1. ABSTRACT
In this paper, temporal, spectral, and structural characteristics of
Robin songs and syllables are studied. Syllables in Robin songs are
clustered by comparing a distance measure defined as the average
of aligned LPC-based frame level differences. The syllable patterns
inferred from the clustering results are used for improving the acous-
tic modelling of a hidden Markov model (HMM)-based Robin song
detector. Experiments conducted on a noisy Rocky Mountain Bi-
