This paper presents a set of novel duration features for detecting pitch accent and phrase boundaries, which depend on articulatory timing rather than segmental duration information. The features are computed from the detected syllable nuclei and boundaries, using peaks and valleys in an energy contour but also leveraging information from a simple HMM phone manner class recognizer to increase recall. In experiments on the hand-segmented TIMIT corpus, we obtain greater than 90% Fmeasure for… CONTINUE READING
