Presented by Paul Nisbet and Abi James at the BDAN International Conference, March 2014. Since 2012 the JCQ Access Arrangements have acknowledged that candidates using a Computer Reader or text-to-speech technology are reading independently making such provision available to candidates in exams that test reading skills for the first time. While use of digital exams with text-to-speech has been widely supported in Scotland through the work of SQA and CALL Scotland for a number of years, the rest of the UK has not had equivalent access. From 2013/14 exam boards in England, Wales and Northern Ireland propose to provide digital versions of exam papers to schools for text-to-speech users. This paper will draw on experiences in Scotland and the work of the BDA New Technology Committee to identify processes and best practices within schools for using these digital papers and to identify the best text-to-speech technology to maximise the benefits for students.

SQA Assessment Arrangements Assessment arrangements allow candidates who are disabled and/or who have been identified as having additional support needs appropriate arrangements to access the assessment without compromising its integrity.

Assessment Arrangements 2013 Requests for Assessment Arrangements made for Scotland: 17,263 candidates (11.3% of candidates) Rest of UK: 145,430 candidates (6.9%) Requests made for 61,680 entries (exams) (8.3% of all entries in Scotland) 6. Assessment Arrangements 2013 Scotland Rest of UK Requests for Access Arrangements 17,263 candidates (11.3%) 145,430 candidates (6.9% - many arrangements delegated to schools) Extra Time 76% 59% Reader 30% 27% Scribe 24% 15% Use of ICT including digital papers 19% n/a - use of word processing delegated to schools Computer readers 2% 0.4% Coloured paper (excludes coloured overlays) 3% 2% 7. Computer Reader (TTS) vs. Human Reader TTS offers an independent means to decoding text. TTS provides greater consistency. Human readers can be more flexible (can read anything). Some learners prefer to use TTS. Studies have shown candidates are more likely to check questions with TTS than using a human reader, resulting in higher scores (Dolan et al, 2005) Computer Readers are allowed in ALL exams, including all GCSE, A-level & Functional Skills exams including those testing reading skills since it allows the candidate to independently meet the requirements of the reading standards 8. A 6th year pupil at Denny High in Falkirk was assessed using the Neale Analysis, reading with and without text-to-speech. Reading herself, her comprehension age was 6 years 9 months. With text-to-speech, it was over 13 years. 9. 2002 need for Digital Question Papers with TTS identified 2003-04 research into specification; development of papers 2004-05 evaluation in 6 schools 2005-06 pilot trials #1 - 31 students used digital papers in 105 examinations 2006-07 pilot trials #2 - 80 candidates used 490 digital papers in 200 examinations 2014 Rest of UK PDF papers will be provided by exam boards (not interactive); UKAAF guidance The Scottish Experience: Research, Development and Trial 10.

Voice quality Problem Solution many of the students commented that the synthetic voice was of poor quality and was difficult to understand Nisbet, P.D., Aitken, S., Shearer, N.

Pronunciation Problem Solution Text to speech doesnt read every word accurately, 1928 would be read as one thousand nine hundred and twenty-eight. Words are mispronounced, in particular names and places, which can affect the smooth reading of longer passages. Words containing an apostrophe are not read correctly. Nisbet, P.D.

CereProc updated the voices to fix the pronunciation. 4. Or use a TTS tool with a pronunciation editor. 19. 3. Unreadable image text Problem Solution Some text is an image and cannot be read by the computer: 1. SQA desktop publishers now replace image text with text boxes with selectable, readable text. 2.
