What is Captioning?

Captioning – synchronized text transcript of multimedia content.

Transcript – text representation of the spoken words and sounds.

Audio Description – verbal statement of on-screen visuals.

5 Stages of Accessibility Awareness *

► Denial – Accessibility laws don’t apply to my organization.

► Anger – Accessibility laws are so unfair and unreasonable!

► Bargaining – I’ll make my home page accessible, but I can’t possibly make software for all my employees and customers.

► Depression – I’m so overwhelmed. I don’t even know where to start. This is impossible. I give up.

► Acceptance – I understand accessibility is key to universal design. I’m moving in the right direction.

* inspired by Derek Featherstone

Objectives of Accessibility Laws

► Equal opportunity

► Independence

For most people technology makes things easier.

For people with disabilities, technology makes things possible.

Accessibility Laws: FederalUnited States Federal Laws

Section 504 of the 1973 Rehabilitation Act (Federal)

“No otherwise qualified individual with a disability in the United States …shall be excluded fromthe participation in, be denied the benefits of, or be subjected to discrimination under any program or activity receiving Federal financial assistance” ericec.org/sect504.html

21st Century Communications and Video Accessibility Act

Passed October 8, 2010 – Signed into law by Obama

Extends closed captioning obligations to video programming provided by, or generally considered comparable to programming provided by, a television broadcast station, even when distributed over the Internet:

Covers video programming that was previously captioned for television viewing, live video programming, and new video programming provided by or generally considered to be comparable to programming provided by multichannel programming distributors;

Does not cover user-generated content (e.g., YouTube videos posted by individuals)

Captioning & Universal Accessibility Universal Access:

Accommodate hearing and learning disabilities

Usable by as many people as possible

Remove Language Barriers:

Student not a native English speaker (ESL)

Lecturer not a native English speaker (ESL)

Improving Comprehension:

Studies show captioning improves comprehension and retention for all viewers

Mobile/Noisy Environments:

Students access content in all unexpected places

Captioning & Improved Comprehension• “Augmenting an auditory experience with captions more than

doubles the retention and comprehension levels.” Gary Robson, The Closed Captioning Handbook

• “People retain about 20% of what they hear, 30% of what they see, and 50% of what they hear and see.” Dales Learning Cone of Experience (www.willatworklearning.com/2006/10/people_remember.html)

• Adult students that used captioned video presentations progressed significantly better than those using traditional literacy techniques. Benjamin Michael Rogner, Adult Literacy: Captioned Videotapes and Word Recognition

• Dual Coding Theory postulates that both visual and verbal information are processed differently and along distinct channels with the human mind creating separate representations for information processed in each channel. Allan Paivio, University of Western Ontario

Captioning & Findability Is your multimedia...

Everyone loves a booming market, and most booms happen on the back of technological change. The world's venture capitalists, having fed on the computing boom of the 1980s, the internet boom of the 1990s and the biotech and nanotech boomlets of the early 2000s, are now looking around for the next one. They think they have found it: energy.

Many past booms have been energy-fed: coal-fired steam power, oil-fired internal-combustion engines, the rise of electricity, even the mass tourism of the jet era. But the past few decades have been quiet on that front. Coal has been cheap. Natural gas has been cheap. The 1970s aside, oil has been cheap. The one real novelty, nuclear power, went spectacularly off the rails. The pressure to innovate has been minimal.

In the space of a couple of years, all that has changed. Oil is no longer cheap; indeed, it has never been more expensive. Moreover, there is growing concern that the supply of oil may soon peak as consumption continues to grow, known supplies run out and new reserves become harder to find.

The idea of growing what you put in the tank of your car, rather than sucking it out of a hole in the ground, no longer looks like economic madness. Nor does the idea of throwing away the tank and plugging your car into an electric socket instead.

Boot hoses a booming market, gloved capote booms happen heart the back of technological change. The world's venture capitalists, house fed gem's the computing boom of the 1980s, the internet boom of the 1990s and the biotech and nanotech boomlets of the early 2000s, are now looking around for the road one. They gaunt they have found bubonic: energy.

Many past booms have been energy-fed: coal-fired steam power, oil-fired internal-combustion engines, the rise of electricity, even the brushy tourism of the jet era. But the past few decades have been quiet on magic front. Coal has been cheap. Natural gas gross hoist cheap. Jennifer 1970s aside, oil has been cheap. The one real novelty, nuclear power, went spectacularly off tabloid rails. The burping to innovate has been minimal.

In local space of a couple of years, all that has paycheck. Oil is no longer cheap; indeed, it has never been more expensive. Moreover, there is fizzled translogic that the supply of oil may soon peak as consumption rains to grow, known supplies run out and new reserves become zipper to find.

The idea of growing what you put in the tank of your car, rather saber sucking it out of a hole in grim ground, no longer looks like economic madness.

Example only: not real data

Research Conclusions► Speech-to-text not ready for this task (error rates >

20%).

► Cost of correcting bad transcript (5%+ error rate) is higher than starting over.

► Using cheap labor costs more due to increased management and quality review costs.

► Need to use trained stenographers for acceptable (compliant) result, but limit their role to only what you need: a transcript.

► Automate everything else.

► Focus on workflow efficiency to minimize resource waste.

How To Get Started – Develop a “Caption Action Plan”

1. Identify multimedia to caption this year• Priorities – public? employees? high-profile content?

2. Select how you will transcribe/caption• In-house• Outsource• Hybrid

3. Obtain necessary training/resources4. Caption multimedia5. Conduct a Plus/Delta

• Plus – what went well?• Delta – what can be improved?

6. Set Phase 2 Caption Action Plan Goals7. Repeat
