With ever-increasing number of car-mounted electric devices and their complexity, audio classification is increasingly important for the automotive industry as a fundamental tool for human-device interactions. Existing approaches for audio classification, however, fall short as the unique and dynamic audio characteristics of in-vehicle environments are not appropriately taken into account. In t...

The advent of the information age has brought massive digital libraries of multimedia and multilingual content. This creates a high demand for multimedia and multilingual indexing and retrieval technologies, e.g. those applicable to audio archives. This paper reports on our development of spoken document retrieval (SDR) technologies, where speech recognition is combined with information retriev...

Classification systems of the audio signals are used for analysis of the input signal and then were used to extract the different characteristics or features of the audio signal. Classification of audio signal is used to draw some sensory and physical characteristics like voice and is used to determine their characteristics. Extraction algorithms can be used vastly, depending on the field of cl...

I T IS WITHIN THE IMMEDIATE MEMORY Of most librarians when there was little consideration given to the place of audio-visual materials in the Iibrary program, since the sole function of the library was construed to be the dissemination of knowledge through the medium of the printed word. Today almost all libraries are making some use of audio-visual materials, in the form of microfilm, filmstri...

We investigate the self-localisation problem of an adhoc network of randomly distributed and independent devices in an open-space environment with low reverberation but heavy noise (e.g. smartphones recording videos of an outdoor event). Assuming a sufficient number of sound sources, we estimate the distance between a pair of devices from the extreme (minimum and maximum) time difference of arr...

One of the largest selling points for The Weather Channel (TWC) is the ability to generate localized content for its subscribers, specifically local weather forecasts. To facilitate this localized content, TWC deploys smart devices in cable head ends. These smart devices are called STARs (Satellite Transmitter Addressable Receivers) and are responsible both for collecting weather data and displ...
