Abstract
This paper descirbes a technique for finding intonatioanl
events, (pitch accents and boundary tones) from waveforms.
The technique works in a bottom-up manner by
using a recurrent neural network to perform a classification
of each frame in the input waveform. An autosegmental
description, consisting of intonational events, syllables
and the links between them, is then produced from
this frame-based classification. The technique correctly
identifies 85.7% of pitch accents and boundary tones.
