Miscommunication handling in spoken dialog systems based on error-aware dialog state detection

With the exponential growth in computing power and progress in speech recognition technology, spoken dialog systems (SDSs) with which a user interacts through natural speech has been widely used in human-computer interaction. However, error-prone automatic speech recognition (ASR) results usually lead to inappropriate semantic interpretation so that miscommunication happens...

Detection, Measurement, and Enhancement of Happiness

near future, we expect the happiness research on information technology will become a new subject, “Happiness Informatics,’’ and have an impact on society. Jhing-Fa Wang Chung-Hsien Wu Shulan Hsieh

Robust dialogue act detection based on partial sentence tree, derivation rule, and spectral clustering algorithm

A novel approach for robust dialogue act detection in a spoken dialogue system is proposed. Shallow representation named partial sentence trees are employed to represent automatic speech recognition outputs. Parsing results of partial sentences can be decomposed into derivation rules, which turn out to be salient features for dialogue act detection. Data-driven dialogue acts are...
