In this paper a new concept for audio classification and analysis is presented to determine the authenticity of the speaker’s environment. The overall concept’s characteristic is determined though an introduced Verifyer-Tupel which enables a detailed analysis of every kind of media. The purpose, the practise as well as the need of this Verifyer-Tupel is anchored in forensics. As we are clarifyi...

At ATR, we are collecting and analysing ‘meetings’ data using a table-top sensor device consisting of a small 360degree camera surrounded by an array of high-quality directional microphones. This equipment provides a stream of information about the audio and visual events of the meeting which is then processed to form a representation of the verbal and non-verbal interpersonal activity, or disc...

In this paper an improved version of an integrated environment that improves the mobility of blind persons into a limited area is presented. For the first time, the concept of the audio virtual realty is introduced here, as a manmachine interface between the subject and the wearable equipment that guides the movement. Other improvements are regarding the sensors used to acquire data from the su...

Important information is often generated at meetings but identifying, and retrieving that information after the meeting is not always simple. Automatically capturing such information and making it available for later retrieval has therefore become a topic of some interest. Most approaches to this problem have involved constructing specialized instrumented meeting rooms that allow a meeting to b...

We present a new approach to modeling and processing multimedia data. This approach is based on graphical models that combine audio and video variables. We demonstrate it by developing a new algorithm for tracking a moving object in a cluttered, noisy scene using two microphones and a camera. Our model uses unobserved variables to describe the data in terms of the process that generates them. I...

This paper presents analysis results of the effects an instrument cable has on the timbre of an electric guitar. In typical, well-designed audio equipment with proper impedance buffers, the effect of the cable can be considered insignificant at audio frequencies. In contrast, magnetic pickups used in electric guitars, act as resonating low-pass filters. The cable is attached to a resonating ele...

In general, most systems for face and speaker identification are tested on high quality data collected in well-lit and quiet environments. In this study, we investigate the application of existing face and speaker identification techniques to the task of user authentication on a handheld device. In this context, the audio/visual capture hardware is of lower quality than equipment typically used...
