It is well known to enhance the performance of noise robust speaker identification using visual speech information with audio utterances. This paper presents an approach to evaluate the performance of a noise robust audio-visual speaker identification system using likelihood ratio based score fusion in challenging environment. Though the traditional HMM based audio-visual speaker identification...

We report the results of a pilot study that explores potential uses for BrailleTouch in the instruction of braille literacy for the visually impaired. BrailleTouch is an eyes-free text entry application for smart phones. We conducted individual semi-structured interviews and a focus group with four domain expert participants.

Sensory Aids Foundation engaged in a study examining computer-aided instruction (CAl) with 15 visually impaired students. Off-the-shelf educational software was adapted for use with a speech synthesizer. Students were tutored in typing, spelling, and language skills. The study was conducted for approximately 6 months, and the results were analyzed and are discussed in this paper.

Digital audio is becoming increasingly popular in higher education with faculty digitally recording and broadcasting lectures for students to learn-on-demand. Students have discovered accelerated playback features in popular computer software and use it to reduce the amount of time spent listening to audio-enhanced instruction. In the current study, 183 undergraduates were randomly assigned to ...
