In recent years, rapid growth of the Internet and Instant Messaging (IM) technology makes IM a popular communication tool. In the meantime, Internet trend is evolving into the new generation, Web2.0, with emphasis on user co-constructing cyber contents. People around the world communicate with each other via on-line IM all day long. If you are stuck in an unfamiliar place and need assistance, asking assistance through IM service is a warrant that support will be delivered to you in time. Therefore, we propose to combine Google Talk (GTalk) of handheld devices with IM service over Web 2.0 forming a support system to assistance tourist travel in unfamiliar areas with confidence. When you need assistance, the content of your question message is input into a speech server by constructing an analytical model for Speech Interface Languages (SILs) system. The speech server translates your speech into text and sent out to IM Web 2.0 group for answering. Later on, when you log in the GTalk again, assistance will come to your hand at once. Because so many people are using on-line IM for 24 hours, the system should be very helpful for tourist around the world. Our system is now going on feasibility study and a large scale of experiment will conduct when we collect enough response about the system.
