Abstract: Videoconferencing is a growing trend among businesses, as the systems reduce need for travel, in turn reducing cost and carbon footprints, and increasing productivity. There has been steadily increasing growth in the industry. However, the main drawbacks appear to be the large startup cost for equipment and installation, the need for professional IT maintenance and setup, and overall ...

Link-11 is a tactical digital communication network standard deployed in military platforms now for several decades. The standard employs the digital modulation technique Differential Quadrature Phase Shift Keying (DQPSK) to encode formatted binary messages (M-series messages) onto an audio channel, which are then modulated and transmitted over a radio communications network. Testing of the var...

The work describes the process of building a telephone-based interactive voice response (IVR) system. For the collection of audio data for speech recognition, webbased audio recorders are used so that technical audio equipment does not have to be shipped to the countries with the language in question. However, some parts of the world do not have an Internet infrastructure at all or only a slow ...

MEASURING THE LINEAR AND NONLINEAR PROPERTIES OF ELECTRO-ACOUSTIC TRANSMISSION SYSTEMS F. Heinle, R. Rabenstein, and A. Stenger Lehrstuhl f ur Nachrichtentechnik, Universit at Erlangen-N urnberg frabe,[email protected] ABSTRACT Competitive audio consumer products require not only cheap signal processing hardware but also low-cost analog equipment and sound transducers. Th...

Recording lectures for later use is a method used by instructors for some time as a means of helping students learn course material and prepare for exams. Except in distance education courses where recorded lectures may be necessary, the method has not been widely adopted, however, probably due to the extra effort and resources required to produce instructive recordings and make them available ...

The centralised control rooms of large industrial plants have separated people from the processes they should control. Perception is restricted mainly to the visual sense. Only telephone or radio links provide narrow-band voice communication with maintenance personnel down in the plant. Multimedia equipment can perceptionally bring back the operator into the plant while bodily keeping him the c...

Bluetooth Wireless Technology can overcome some of the limitations of the conventional audio-guided tour systems that a growing number of museums, aquariums, and similar institutions offer to visitors. Such systems are designed to enrich the experience of visitors while generating revenue for the institution. Conventional systems, such as those developed by Acoustiguide and TourMate, are implem...

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...

Numerous wind displays have been developed to provide sensation in virtual reality applications. However, previous studies, required the production of physical using a source. To release cold or hot wind, large equipment for making air temperature changes. In this study, we propose induce pseudo-wind perception, perceiving even absence visuo-audio-haptic cross-modal effects. We audio-visual sti...
