Study on detection of prosodic phrase boundaries in spontaneous speech

Hui Sun, Mingxing Xu, Wenhu Wu

Prosodic information, which has the abilities of disambiguation, improving the parsing of the spoken language and predicting recognition errors, becomes more and more important in speech recognition and understanding, especially in spontaneous speech. In this paper, we investigate the detection of the phrase boundaries by prosodic features in the domain-specified Chinese spontaneous speech. The ultimate goal is to use these detected boundaries in the recognition and understanding component of EasyFlight, a Chinese spoken dialogue system for querying and booking flight tickets, to improve the system performance. In the experiment, we use more than 30 prosodic features for detecting four types of the prosodic phrase boundaries and obtain a correct detection rate over 85%.
