What alternative formats does Ally generate?
Ally provides alternative formats for these file types:
- PDF files
- Microsoft® Word files
- Microsoft® Powerpoint® files
- OpenOffice/LibreOffice files
- Uploaded HTML files
These alternative formats can be generated:
- OCR’d version (for scanned documents)
- Tagged PDF (currently for Word, Powerpoint and OpenOffice/LibreOffice files)
- Mobile-friendly HTML
- Electronic Braille
- Translated Version
- Translated Version is disabled by default. Administrators can submit a support case to have it enabled.
- BeeLine Reader
Are alternate formats generated when a request to download is made?
When a particular alternative format for a particular content item is requested for the first time, Ally generates this on demand. In most cases, this completes within 1-2 minutes.
As soon as it has been generated, the alternative format is downloaded. Ally then also caches the result, so any additional requests for the same alternative format can be served and downloaded from cache immediately.
Does Ally generate alternative formats for student content?
Ally currently only processes instructional content. For example, content added by someone with edit permissions in the course, such as the instructor or instructional designer. Ally currently does not process student content or student submissions.
What format is the OCR’d alternative format?
The OCR’d version is made available as a tagged PDF.
What format is the Audio alternative format?
The audio alternative format is made available as a downloadable MP3 file. We also add some of the extracted semantic information into the speech, which adds additional structure to the audio and makes it easier to follow.
Which Braille code does Ally use for the Electronic Braille Format?
Ally uses Braille Ready File (.brf) as the electronic Braille format. The braille code used depends on the language the document is in. For English documents, Ally uses Grade 2 Unified English Braille (contracted).
Can the Ally Electronic Braille Format be printed using a Braille printer?
The Braille Ready File (.brf) format can be used for both electronic braille displays and braille embossers (printers).
You still need to check whether a specific Braille embosser/printer supports the .brf format.
Why do I see "The alternative formats for this file have been disabled"?
Instructor and administrators can turn off alternative formats for an individual content item within a course. For example, on a file uploaded to the course.
What does the instructor need to do to generate alternative accessible formats for a content item?
Nothing. Ally automatically picks up on any existing or new materials, runs it through the accessibility checklist, and makes the alternative accessible versions available to both the student and the instructor.
Is there a file size limit?
There is no file size limit for the checking of content for accessibility issues. It is possible that particularly large or complex files can fail to be checked.
There is a 50MB file size limit for fixed files that are uploaded directly through the Ally instructor feedback.
There is no limit on the generation of alternative formats, including the HTML alternative format. It is possible that the alternative formats for particularly large or complex files can fail to generate. There are exceptions:
- There is a 30MB / 100 page limit for generating the OCRd alternative format for scanned documents. The OCRd alternative format is a pre-requisite for generating the other alternative formats for scanned documents.
- There is a 100,000 character limit for the audio alternative format. This character limit typically corresponds to at least 30 pages or several hours of audio.
How does Ally handle password protected content?
Ally detects password-protected content, gives them a 0% accessibility score and provides guidance to help remove the password through the instructor feedback. Ally does not generate any alternative formats for password protected content, as we can’t get access to the actual content.
Can I disable alternative formats?
Yes, administrators can disable alternative formats.
