NVDA e-Speak Text-to-Speech Project Update (March 2014)

Posted by Suman Dogra at Mar 18, 2014 07:00 PM |
CIS in partnership with the Daisy Forum of India is engaged in a project supported by The Hans Foundation to develop enhancements to the open source screen reader for Windows NVDA (Non Visual desktop Access) and e-Speak text-to-speech synthesiser in 15 Indian languages.

Under the NVDA project, we have been working in the past year on issues relating to Excel, Power Point and MS Outlook. The issues which have been fixed are:

  • 3680 : Read all formula in excel sheet (NVDA+f7).
  • 3681 : Read all comments in excel sheet (NVDA+f7).
  • Finished implementation for 'viewing modes' supported like Cells-Flat, Row-Cells, Column-Cells, etc.
  • Pressing NVDA+f7 will print a dialog box. This has a choice to show cells with comment or formula. Pressing 'Enter' at any selection in the tree will close dialog and select cell or area.
  • 3231: NVDA incorrectly speaks previously entered but later deleted characters when the space bar is pressed in PowerPoint.
  • #3538: Office 2010, NVDA now reads the selected symbols in the insert|symbols dialog box in Word and Excel 2010.
  • #2921: In Excel, NVDA will say 'has comment' if the cell has a comment in it.
  • #3043 : In Excel, Ctrl+A doesn't notify the change in selection.
  • #1938 : In word 2007 and 2010, NVDA does not automatically speak the error text in the spell checker dialog after the first time the dialog is launched if the focus is already in the error text field.
  • Ctrl + Up and Down arrows in Word now skip blank paragraphs.
  • #3431: Spell check in Word 2010 now reads the correct context error text instead of reading all bolded text in the context.
  • #3290: Bulleted text is now correctly read with Ctrl+Up and Down arrows.
  • #1686: Protected documents are now read in Word 2010.
  • #649: Status bar in Word Office 2010 is now read.
  • #2816: Auto complete suggested contacts in Outlook 2010 are now read.
  • 2047: Language detection in Word is available now.

Some of these fixes are available in NVDA and can be downloaded from www.nvaccess.org. The info about these fixes can be checked in what’s new section of the application at the website.

We have also been working on some documentation for the project, primarily FAQs to cater to the community’s needs for users switching from Jaws to NVDA which is available at http://code.google.com/p/saksham-projects/wiki/Tutorials.
