Adding Automatic Speech Recognition (ASR) captions to DSpace repository videos

In August of 2017, I experimented with adding captions for the Deaf and hard of hearing to over 300 videos in our institutional repository using automated speech recognition technologies, and the results were… interesting.

Experimental visualizations of availability status for Electronic Theses and Dissertations

When I visited Cape Town, South Africa this year for the exchange program between the libraries at Virginia Tech and Cape Peninsula University of Technology, I was inspired by three projects related to statistics and visualization:

In Remembrance of Ebony Morgan

I met Ebony Morgan three weeks ago on June 11, 2017 – a Sunday. We were traveling on the Smart Way Connector bus from the Amtrak train station in Lynchburg, Virginia to the civic center in Roanoke. I remember Ebony in particular because, though there were many passengers on the bus that evening traveling to Roanoke and Blacksburg, we were the only passengers seated in the very back of the bus. We interacted.

Yesterday, I saw the tragic news that Ebony had been killed. I am saddened and compelled to remember her.

Visit to Cape Peninsula University of Technology

I’ve arrived and settled in Cape Town for my visit with Cape Peninsula University of Technology (CPUT) as part of an international outreach initiative between the University Libraries at Virginia Tech and CPUT Libraries.

Cape Town has been a wonderful place to visit. Ocean, mountains, and dense city are all within walking distance of one another. The city is multicultural.

In some ways, this makes things too easy for the American traveler. The multicultural residents of the city tend to be multilingual; there are eleven official languages in South Africa. Most people here are bilingual, and it is common in this city to find people who speak three, seven, or nine languages. Everyone that I have interacted with speaks English, which makes it easy to get around, but also removes much of the motivation to learn new words. At the present time, schools deliver most instruction in English. Signs at the university often have text in three languages:  Afrikaans, English, and isiXhosa.

Food and necessities tend to be affordable because of the exchange rate. I’ve tried some local cuisine that I wouldn’t have tried at home, but if I wasn’t inclined, I would never need to do so. Every variety of food is available here because of the many cultures and tourists.

There are many tourists here, but I suspect that at least some of the daredevils that paraglide from mountains over towers to the beach are locals. The people add vibrancy to the area, and are always doing something interesting, like dancing on the beach at sunset.

Artists live here, and have painted murals on some of the buildings. This art is a tribute to the missing Nigerian schoolgirls, and features Bat Mary, Super Mary, and Super Jesus.

Bat Mary and Super Mary are barely visible in the top right corner.

It is approaching winter here and the daylight hours are short, but the weather has been exceptionally pleasant. Late fall in Cape Town has felt like late spring in Blacksburg, but with much less rain. Afternoon skies have been clear blue nearly every day. This is problematic. Winter is normally the rainy season, but Cape Town is experiencing a three year drought. Reservoir levels are critically low, and residents of the city have become good at conserving water. I’m trying to do my part, and am now comfortable with a procedure I’ve named the Cape Shower, which uses more water than an astronaut shower but less than a Navy shower. This is a habit that I need to take home with me.

I’ve had new experiences and seen many new things since I’ve been in South Africa. I’ve seen some wildlife that I never think about in Virginia. The flowers here are vygie – ice plant and sea fig – and native to South Africa.

This odd bird is called “hadeda”.

The people of CPUT Libraries and the CPUT Centre for Technology Services have been very busy, both in showing me the area and teaching me about their projects.

Here are Lula, Herbert, our friend Veliswa (who visited Virginia Tech last year), and Vuyo enjoying lunch in the cafeteria.

I’ve been trying to learn as much as I can, and to give occasional help when something is already within my experience. I’ll write more about some of these later, but for now I can give a summary:

  • Discussion with Debbie and Lovemore about two software platforms for collecting and presenting library statistics, including an operational, custom developed stats database, and a partially developed solution utilizing Splunk
  •  Discussions with the disability units on two campuses
  • Exploring techniques with Hillary for adding closed captions and subtitles for the deaf to videos
  • Lessons from Lovemore about the architecture of an award winning PhoneGap (now Apache Cordova) CPUT app for Android, Blackberry, and iOS
  • Working with Lulamile and Herbert on DSpace repositories, including brainstorming about ORCID, researcher profiles, and the REST API, and assistance resolving issues with PDF thumbnail generation and OAI-PMH harvesting.
  • Observing the pre-show setup for a video streaming event
  • Demonstration from Janine of an online information literacy course, and initial discussion about an information literacy app

I’ve visited the Bellville and Cape Town campuses; next week I’ll visit the Wellington campus to learn even more, and the Mobray campus to talk about some of the strengths of Virginia Tech.

One month after release, our app has six users

On September 12, 2016, Virginia Tech Library Labs released ReResolver to the App Store for iPhones.

ReResolver is a digital preservation project for the library – an attempt to revive software that has been lost by the advance of technology. We revived Resolver, an app by the now defunct Fancy Pants Limited,  which helps indecisive people make choices. Our method of bringing the software back to life was by rewriting it from scratch. I described the effort in a blog post, and also wrote in another post about adding accessibility features to the app. The code is open source and available on GitHub.

Thus far, according to iTunes Connect, the app appears to have 6 users.

Movie Theater Closed Caption Equipment 2: The CCR-100 from USL, Inc.

Last week I went to a movie theater to test another type of closed captioning equipment. Previously, I had tested the Sony Entertainment Access Glasses available at Regal Cinemas. You place the glasses on your head (of course) and captions appear in the lenses. The captions move as your head moves.

This system was different. The CCR-100 from USL, Inc. looks somewhat like a ViewMaster on a stick. It’s designed to fit inside the cup holders in movie theater seats. A long stem leads up to a viewing box where the subtitles appear. The stem is sturdy but flexible, so that the viewer box can be adjusted to the proper angle, location, and height in front of the viewer.

Software Preservation Dilemma: Accessibility versus Authenticity

In a previous blog post, I introduced Re-Resolver, our experimental software preservation project in which we attempt to recreate the classic, but no longer functional iOS app Resolver by analyzing its features and rewriting the app from scratch. Re-Resolver is open source and available on GitHub, and will be made available on the app store later this summer.

With the project, we are exploring this method of software preservation to find questions. Is this really preservation, or is it something else? Is this method worth the effort?

In this blog entry I’ll focus specifically on one unexpected dilemma that came up while trying to duplicate the original app: the conflict between accessibility and authenticity.
