We propose a voice and mouse input interface for 3D interaction in virtual environments. One of our requirements is that we want a user interface that would work naturally with standard equipment. We performed an experiment to measure the efficiency of using voice in addition to the mouse input device for acquiring target objects randomly placed in the 3D virtual environment. Our preliminary st...

We present a session initiation protocol (SIP) network design for a voice-over-IP network to prevent congestion caused by people calling friends and family after a disaster. The design increases the capacity of SIP servers in a network by using all of the SIP servers equally. It takes advantage of the fact that equipment for voice data packets is different from equipment for signaling packets i...

Spam over Internet Telephony as the distribution of unwanted voice messages over Voice over Internet Protocol networks is an upcoming threat. It is harder to prevent than e-mail spam since its content is not available before the victim is annoyed. This is even more difficult if the spam is sent directly to the victim’s user equipment, bypassing the proxies of the service provider. Hence, this m...

We have assembled a system using a personal computer workstation equipped with standard office software, an audio system, speech recognition software and an inexpensive radio-based wireless microphone that permits laboratory workers to enter or modify data while performing other work. Speech recognition permits users to enter data while their hands are holding equipment or they are otherwise un...

Voice over IP (VoIP) service has been widely deployed over the prevalent Internet due to the advanced technologies of digital voice compression, communication protocols, and wired/wireless networks. VoIP then benefitmuch lower cost of equipment, operation, and better integrationwith data applications than voice communications over telephony networks. On the other hand, VoIP further introduce se...

The AT&T VOICEBUILDER provides a new tool to researchers and practitioners who want to have their voices synthesized by a high-quality commercial-grade text-to-speech system without the need to install, configure, or manage speech processing software and equipment. It is implemented as a web service on the AT&T Speech Mashup Portal. The system records and validates users’ utterances, processes ...

Assistive technology can help disabled students function better in most educational situations. This technology includes devices and equipment such as pencil grips, picture boards, alternative keyboards, touch screens, speech synthesizers, voice recognition systems, talking calculators, tape recorders and optical character recognition systems. Several web sites are included for additional infor...
