Navigating a Spatialized Speech Environment
نویسندگان
چکیده
This thesis presents a system for browsing and navigating a database of recorded speech. It uses a spatialized audio environment, taking advantage of the human ability of simultaneous listening. A browsing environment is provided in the form of a virtual acoustic hallway. The user hears several audio recordings simultaneously; each stream of audio is of a specific topic coming from several "virtual" doors along the hallway. The user's head position in real space controls the rate of movement past the doors and the subsequent playing of the audio recordings. Behind each door is heard a "Braided Audio" collage of related news stories. Listening to an individual news recording for a given topic is accomplished in "Audio Rooms" through a new method of selection and representation based on the metaphor of a "FishEye" lens.

متن کاملContextual Awareness, Messaging and Communication in Nomadic Audio Environments
Nomadic Radio provides an audio-only wearable interface to unify remote information services such as email, voice mail, hourly news broadcasts, and personal calendar events. These messages are automatically downloaded to a wearable device throughout the day and users can browse them using speech recognition and tactile input. To provide an unobtrusive interface for nomadic users, the audio/text...
متن کاملNelson, Wt-1 Monitoring the Simultaneous Presentation of Spatialized Speech Signals in a Virtual Acoustic Environment
The effect of spatial auditory information on a listener’s ability to detect, identify, and monitor multiple simultaneous speech signals was evaluated using virtual audio technology. Factorial combinations of three variables the number of localized speech signals, the location of the speech signals around the horizontal plane, and the sex of the talker were employed using a within-subjects desi...
متن کاملDoppelLab: Spatialized Data Sonification in a 3D Virtual Environment
This thesis explores new ways to communicate sensor data by combining spatialized sonification with data visualiation in a 3D virtual environment. A system for sonifying a space using spatialized recorded audio streams is designed, implemented, and integrated into an existing 3D graphical interface. Exploration of both real-time and archived data is enabled. In particular, algorithms for obfusc...
متن کاملSurvey of Methods for Modeling Sound Propagation in Interactive Virtual Environment Systems
This paper surveys concepts, algorithms, and systems for modeling sound propagation in interactive virtual environment applications. First, we review physically-based geometric algorithms for modeling the propagation of early arriving sound waves. Second, we describe perceptually-based statistical techniques that provide late reverberation effects. Finally, we compare auditory display systems t...
