Research And Application Of VUI Based On VoiceXML

In recent years, Voice recognition and voice synthesis technology have made considerable progress based on the rapid development of computer hardware and software technolygies. Some simple human-computer interaction systems based on pronunciation have already appeared in our life. But it is are easy to find that the voice of these systems sounds in using so bad and the level of interaction is so low. It influence the user's mood and interaction efficiency seriously. Then, under some scientists' research, the concept of the Voice User Interface (VUI) is proposed. VUI is a cross course study, combined with linguistic, psychology, engineering and computer knowledge. It's not only been required to study on the technology, but also need to study on the interaction method, behavior model with voice. When the concept of VUI is proposed, it becomes the research focus of the field of human-computer interaction in the whole world. But in our country, there are still few people engaged in research in this respect. We are still at the starting stage. So the essay wish to offer some positive help for VUI through exploration and study in this respect.The essay does study on the general principle of the design and practice of VUI, and try to propose the interaction model of it. And design a rough model system(Lib book checking system) based on the model with VoiceXML technologies. User is allow to talk to computer on the brief and record information. The essay also gives our the systematic structure and framework.This essay finally propose couple of mature designing points and relevant solution through the study and analyze towards the problems raise of the application. These points and solutions are greatly complete and improve the systemIt can be seen that the friendly VUI could make up the shorts of the technologies. It's natural user feeling will works very well on the efficiency. And this topic is worthy to be keep going.
