Original Kurzfassung:
We present a simple and intuitive spectral feature for detecting
the presence of spoken speech in mixed (speech, music, arbitrary
sounds and noises) audio signals. The feature is based on some
simple observations about the appearance, in signals that contain
speech, of harmonics with characteristic trajectories. Experiments
with some 70 hours of radio broadcasts in five different languages
demonstrate that the feature is very effective in detecting and delineating
segments that contain speech, and that it also seems to be
quite general and robust w.r.t. different languages.
