This paper describes two types of auditory interfaces for controlling a word processing application primarily for blind computer users. They are based on the playback of one to three simultaneous sound sources, one of them representing the currently selected menu item and the other two representing the previous and the following item. The gentle background music with changing pitch offers additional feedback about the current location of the user in the menu three.

COBISS.SI-ID: 6948436This paper describes an extension of the Java speech synthesis module which adds the functionality of real time manipulation of the speaker's spatial position. It is based on a combination of software and hardware signal processing techniques which improves the elevation localization by the use of additional HRTF library. It enables also the use of multiple simultaneous voices with changeable pitch and speaking rate. The spatial speaker is implemented as an individual Java module which can be imported and used also in any other Java based application.

COBISS.SI-ID: 7333972This paper describes a software solution which enables spatial manipulation of synthesized speech. The system is a potential upgrade of the existing screen readers which would describe the information on the spatial position of various GUI elements by the original spatial position of synthesized speaker.

COBISS.SI-ID: 7307348This paper describes a reading system for visually impaired and blind users which reads an arbitrary text from various types of files. The text in the files needs to be marked with special tags which define the use of specific voice, its spatial position and speaking rate. The system recognizes and interprets individual segments of text based on the starting and closing tags. We believe such system represents an imitation of audio books which are used by blind users instead of classic text books. Their variety is very limited and they are often inaccessible.
