“…The agreement between these two transcriptions was high (r ¼ 0.87, p 5 .01). Error responses were categorized based on phoneme error patterns (see also Papadopoulos et al, 2008) that were considered phonological in that the error resulted in a change in the auditory representation of the word.…”

“…Papadopoulos, Argyropoulos, and Kouroupetroglou (2008) examined intelligibility and comprehensibility performance of students with and without visual impairments who were asked to repeat acoustic patterns produced by synthetic speech. The participants with visual impairments responded correctly significantly more frequently than their sighted peers.…”

This study investigated word intelligibility among sighted individuals and individuals with visual impairments for both natural and synthetic speech. Both groups of participants performed significantly better when identifying words presented via natural speech. The results also demonstrated that individuals with visual impairments were more successful than their sighted peers in understanding words presented via synthetic speech, with experience being the most critical factor in identifying words for the participants with visual impairments. Finally, the findings show the correlation between intelligibility and key factors such as age and the overall use of text-to-speech systems.

We present a novel integrated methodology for the development and production of accessible physics and science books from the elementary up to tertiary educational levels. This language independent approach adopts the Design-for-All principles, the available international standards for alternative formats and the Universal Design for Learning (UDL) Guidelines. Moreover it supports both static (embossed and refreshable tactile) and dynamic (based on synthetic speech and other sounds) accessibility. It can produce Tactile Books (Embossed Braille and Tactile Graphics), Digital Talking Books (or Digital Audio Books), Large Print Books as well as Acoustic-Tactile Books for the blind and visually impaired students as well as but for the print-disabled. This methodology has been successfully applied in the case of blind students of the Physics, Mathematics and Informatics Departments in the University of Athens.

“…It has been shown that blind individuals obtain higher intelligibility scores when compared to sighted individuals (Hugdahl et al, 2004) and that this benefit is also observed for the intelligibility of synthetic speech (Papadopoulos et al, 2008;Pucher et al, 2010a) possibly due to the familiarity effect (Barouti et al, 2013) as blind individuals are exposed to the material more through the use of screen readers and audio books. It was also shown repeatedly that blind individuals show a much higher intelligibility for fast synthesised speech (Moos and Trouvain, 2007;Pucher et al, 2010a), an effect that can be found for a wide range of synthesisers: formant, diphone, unit selection and Hidden Markov Model (HMM) based (Syrdal et al, 2012).…”

In this paper we evaluate how speaker familiarity influences the engagement times and performance of blind children and young adults when playing audio games made with different synthetic voices. We also show how speaker familiarity influences speaker and synthetic speech recognition. For the first experiment we develop synthetic voices of school children, their teachers and of speakers that are unfamiliar to them and use each of these voices to create variants of two audio games: a memory game and a labyrinth game. Results show that pupils have significantly longer engagement times and better performance when playing games that use synthetic voices built with their own voices. These findings can be used to improve the design of audio games and lecture books for blind and visually impaired children and young adults. In the second experiment we show that blind children and young adults are better in recognising synthetic voices than their visually impaired companions. We also show that the average familiarity with a speaker and the similarity between a speaker's synthetic and natural voice are correlated to the speaker's synthetic voice recognition rate.
