Automatic sentiment information extraction of social network articles has many essential applications. Following the valence-arousal space framework, in this paper, two approaches including (1) a weighted graph (WG) and (2) a neural network (NN) model that could predict the valence-arousal ratings of words are evaluated on the Chinese valence-arousal words (CVAW) database provide by the IALP-2016...
A new data-driven approach to building a speaking rate-dependent hierarchical prosodic model (SR-HPM), directly from a large prosody-unlabeled speech database containing utterances of various speaking rates, to describe the influences of speaking rate on Mandarin speech prosody is proposed. It is an extended version of the existing HPM model which contains 12 sub-models to describe various relationships...
In this paper, to improve the gestures' motion smoothness when synthesizing Chinese sign videos, 61 kinds of Chinese hand shape models and corresponding Chinese hand shape codes are proposed, which are used to choose transferring hand shapes by judging the fingers' bending degrees and relationships between the joined sign gestures with obvious motion changes. Besides, we also construct an extending...
A new statistical pitch detection algorithm is proposed in this paper. It first defines frame-based voiced/unvoiced probabilistic measures and between-frame pitch transition probabilities, and then tightly integrates them into an ML search to find the best pitch contour of an utterance. Compared with the pitch detection method of the well-known ESPS software package, the proposed method performs better...
