Nowadays the corporations related to Information & Communication field are researching more and more on VoiceXML development. VoiceXML can provide users with more efficient interface, VUI(VoiceXML User Interface) in web environment than the existing one. But more research and development for designing the Dialog have to be done for VUI to be used in efficient way. That was a main topic in "2002 VoiceXML Conference & Expo". According to the importance this paper presents VoiceXML Dialog designed for the purpose of its efficient use and the experimental result.

이동통신망이 발달하면서 기존의 인프라를 생성하였던 ATM망을 음성서비스에 활용하기 위한 Voice over ATM기술이 많은 발전을 하고 있다. 본 논문에서는 ATM 망에서 Low-bit-rate voice 트래픽을 처리하기 위해 1020개의 커넥션을 지원하는 AAL2 Voice gateway를 구현하였다. 본 논문에서 구현된 AAL2 Voice gateway는 ITU-T Recommendations 1.363.2와 1.366.2에 근거하여 설계하였다. 또한, SSCS(Service Specific Convergence Sublayer)와 CPS(Common Part Sublayer) 부계층을 모두 하드웨어로 구현하였다. 본 AAL2 Voice gateway는 VHDL로 구현되었으며, 이동통신망과 VoDSL의 Voice gateway에서 그 효용 가치가 높을 것으로 사료된다.

The necessity of voice recording device was increased using voice signal IC with designed LSI/VLSI. The control unit which developed here voice recorder has low power dissipation, portable, and comfortable using voice source. However, the Korea voice recorder abilities far behind of foreign products for its performance and size on sailing. So we used Chua circuit to improvement voice quality abilities after minimize power supply device and circuit by designing voice recording device into lower power dissipation power circuit.

In this paper, we propose the method of voice packet transformation for the improvement of voice quality in embedded VoIP system terminals. For this purpose, it was analyzed about the RTP header in the voice packet receiving side and designed about the handling method of voice packets by using jitter buffer. Through this analyzed and designed results, by implementing the voice packet transformation method and testing on the self-product VoIP system, we reached that a conclusion is satisfied with performance of VoIP services.

The most basic means of communication among humans is a voice. Without speaking of voice technologies, we found it is important and convenient to use a voice in everyday life. But. in consideration to speech recognition systems, we can't always desire a normal voice input as input signal to the system. Generally speaking. a pathological voice as against a normal which is a voice with a problem in the larynx. could be also special case of input voice. Of course, but the distortion of a speech signal by environmental effects i.e., noise or transmission channel was a raised problem. we will take up a pathological voices with laryngeal disease which is essential distortion factor in voice. Also, we are to find out the difference of acoustic parameters distribution between normal and pathological voice by a statistical method in our research.

Voice and data are transmitted over a single packetized data communications network which is designed for data communications. The public switched telephone network for voice and the packet data network for data are merging into a single data network to get efficiency and to reduce operational cost. However, integrating voice and data transmission over a single data network is not easy because voice should be transmitted without delay but data should be transmitted without error. Advances in technology begin to overcome basic differences. Several integration methods in voice and data will be examined and reviewed here. Moreover, trends and problems on integration will be also discussed.
