  1. Using the Power of Speech with Maths Dr Abi James Assistive Technology Consultant iansyst

  2. Contents • Uses for speech • Speech recognition & text to speech basics • MathsTalk • Maths & OCR • PDF Accessibility Editor • MathML

  3. Uses For Speech with a computer • Speech recognition (speech input) is an alternative to keyboard input. Also helps with • Poor spelling • Poor or slow handwriting • Speech output read text from the screen. Helps with • Reading • Proof reading • Navigating around computer applications • Accessing computer based tools (e.g. spell checker suggestions)

  4. Speech Recognition: But… But... • Time commitment in enrolment /training • Need • understanding of word processing & punctuation. • ability to multi-task and dictate. • Noise issue • Requires high-powered computer

  5. Speech Recognition in general • Dragon NaturallySpeaking Preferred v9 usual package for students. • Students training on the software and how to dictate as well as voice recognition “training” • Dragon does not recognise specialist vocabulary unless “trained” to do so. • Medical of Dragon Pro available

  6. MathsTalk, Scientific Notebook & Dragon • Scientific Notebooks is a scientific word processor + mathematical computations • MathsTalk enabled Dragon to dictate into Scientific Notebook • User “trains” Dragon to recognise mathematical commands in SN • Need to learn mathematical terms to dictate them

  7. Maths & OCR • OCR software can not recognize math equations • Latest version of Abbyy FineReader • Recognise simple chemical formulae • Incorporates custom word dictionary & medical dictionary (ViOi - b(6i)) /foft,<p) = exp [Igg m)) + c{Vi, 4>))

  8. PDF Files: interactive, colorful, pleasing to the eye • PDF files often used for mathematical papers, worksheets & handouts • Easy to convert from LaTeX to PDF • Text in PDF files can usually be read aloud (PDFAloud included with Read & Write Gold) • But equations and symbols have to added into each PDF file manually through the accessibility editor

  9. Pronunciations: *=times 40. *=times 600 *=approximately *=approximately *=A., *=converts to *=sight-o-plasm *=B. *=might-o-kondria *=C O 2 *=dioxide *=Cyitoplasmic Equations: *=1,1,C 6 H 12 O6 liquid *=2,1,plus 6 O 2 gas *=3,1,converts to *=4,1,6 C O 2 gas *=5,1,plus 6 H 2 O liquid *=6,1,plus energy Courtesy of EA Draffan, www.emptech.info PDF Accessibility Tags Example

  10. MathML • Mark-up language for equations on the web • Displays correctly with zoom in feature • Can be read aloud by text-to-speech engines • IE plug-in:www.dessci.com/mathplayer • Mozilla FireFox native support

  11. Creating MathML • Most scientific publishing programs support MathML through save as/export to html including • Scientific Notebook • MathType (advanced version of Equation Editor) • Plug-ins can support TeX & Word to MathML • Word 2007 will use MathML for equations • Possibility that Read & Write will read aloud equations in Word
