Effective Captioning Strategies: When to Use AI Versus Human

What’s the Difference Between Transcripts and Captions?

Transcriptions are the text form of an audio file. Transcripts include the words you hear and may also include other details, such as background noises, pauses, or music.

Captions are a type of transcript also includes anything isn’t visual, such as sound effects. Captioning divides transcript text into into time-coded chunks known as caption frames. Time-coded frames typically appear on screen as text corresponds to the spoken words in a video.

Having transcriptions and captions available is especially important for those who have little or no hearing, but it also is helpful in situations where it’s inappropriate to listen to something with the sound on. Students also cited using captions and transcriptions to help them focus, retain information, to overcome audio issues, and in studying for exams.

Both captioning and transcripts are alternative formats that provide users with greater accessibility. Here are a few things to keep in mind when you’re thinking about whether to use human or AI for captioning and transcription.

Human and AI Each Have Benefits

There are two main types of transcription or captioning services, human and artificial intelligence (AI). Each option has it’s unique benefits, and depending on your needs, both have advantages to consider based on your application. Chances are that your organization will find a need for both services. It’s less “human versus AI ” and more understanding when each will serve a better purpose for your needs at the time.

Artificial Intelligence Use Cases

If you’re in a time crunch, you can’t beat the speed of AI. The software recognizes speech and translates it to text in real time. YuJa’s AI-based automated speech recognition (ASR) provides captions and transcriptions that are 90-95% accurate on live events and on-demand recorded content.

Over time and usage, the artificial intelligence engine continues to learn and improve.

Some companies go a step further to improve accuracy of AI transcription and captioning. YuJa’s automatic captioning accuracy is validated internally with YuJa Product Team staff on a semi-monthly basis. These tests are carried out on various accents, dialects, and regions of the world to determine the accuracy of the software.

When you need a transcription in multiple languages, AI is a great tool. Sending an audio file out for human transcription in this type of scenario would not only be cost prohibitive, but timely. Many professional transcriptionists only transcribe to their native language, so you would need several people to transcribe one file.

If you need multiple language transcriptions, look for a video solution that provides captioning and transcription in a variety of languages, from English, to Spanish, French, German, French, Mandarin, Arabic, and others.

When to Consider Human Transcription

Because humans have the capacity to understand complex information, human transcription and captioning is the go-to choice for accuracy. YuJa Pro Captioning, professional human captioning, provides 99%+ accuracy.

Language is complex. Humans understand this. We know about and can decipher homonyms. We have the capacity to pick up on changing topics, people using acronyms, interruptions, or speakers with regional dialects or accents, and humans can account for those and other language nuances in the transcript.

While human transcription may take longer to generate, it’s less likely that you will have to go back and re-listen to audio to gain clarity after reading the transcript.

Human transcription and captioning also should be considered in other instances, such as when there are several speakers, when speakers have thick accents, or there is a lot of background noise.

Integration is Crucial

When considering human and AI services for your enterprise or institution, it’s ideal to look for a company that integrates with both. That means the organization understands its customers’ each have unique needs and instances in which human or AI transcriptions and captions would better serve them.

The YuJa Enterprise Video Platform integrates with third-party human captioning services for both automated and manual workflows. Our captioning partners provide ADA-compliant (99%+) captioning solutions to YuJa customers. Caption workflows can also be managed and turned on-and-off when appropriate. YuJa currently supports the following providers: 3Play Media, Rev, Cielo24, AST CaptionSync, as well as some region-specific vendors.

Facilitating Student Learning with Variable Speed Playback

Understanding Variable Speed Playback

Variable speed playback is an option in the Platform’s Media Player that allows students to speed up or slow down playback. Depending on the user’s individual needs, students can cover content quickly for review, or more slowly, for increased understanding and retention. Regular speed playback is 1x, but with YuJa’s Media Player, you can choose speeds from .5x — or half normal speed — to 8x. The “x” indicates how many times slower or faster than normal the video will play, so a one hour video at 4x speed will play in only 15 minutes. Users can easily change speed once or multiple times as they watch a video.

Speeding Up and Slowing Down Playback

Both speeding up and slowing down playback offer a number of advantages to students. Consider the following use cases:

Reviewing Recorded Lectures

Lecture capture isn’t just for online learners. Students may use lecture capture recordings to review classes they attended for improved understanding and retention. When watching a lecture they attended, they may not want to spend as much time reviewing; doubling playback speed allows a one-hour lecture to complete in only 30 minutes.

Preparing for Exams

When it’s time for midterms or final exams, students may want to rewatch several lectures as part of their study strategy. Working your way through a full semester or even half a semester of lectures is challenging at a normal pace, but much more manageable when sped up using variable speed playback.

Online Learning

Students that are using lecture captures without brick-and-mortar classroom time may find it helpful to be able to slow down playback during challenging lectures.  This can offer additional time for understanding and mastery, particularly of technical terminology.  The same strategy is effective for students who are catching up on a missed class.

Language Learners

Students learning another language are frequently able to master the material and understand lectures much more effectively when they can slow down playback. Reduced speed means slower speech and improved comprehension for these learners.

Variable speed playback is one way institutions can give students control over their learning materials.  Other features, like search inside video, search within audio captions, slides, notes, bookmarks and indices, all enable students to quickly search videos for keywords and find areas they need to revisit.

Five Tips for Creating an Effective PowerPoint Presentation

YuJa now has a Software Capture Ribbon that integrates directly with Microsoft PowerPoint. This allows users to automatically sync the start and end of their recording with their presentation. Instructors can also embed their videos directly into their presentation.

Go Big

When recording a PowerPoint, you need to create both visual impact and visual accessibility, regardless of screen size. Choose fonts that are 24 pt. or larger, and opt for clear and readable fonts. Choose images that are bold, interesting, and fill a significant portion of the slide, and keep them relatively eye-catching. Tables, charts and diagrams should be clear and readable, only containing enough text and information to convey the message.

Keep It Simple

Limit each slide to a single idea.  Focus on the key points you’re covering in your lecture. This isn’t the time for pages of text–if you need those, offer them as a downloadable PDF to your students or colleagues. Limit your use of bullet points–consider placing each point on its own slide. Additionally, reducing the amount of text per slide can help students focus more on listening and less on typing.

Focus on Contrast

On a big screen, or in a darkened room, it may be fairly easy to make out light-colored text on a light-colored screen; however, that gets much harder when you’re watching a lecture capture on a smartphone outside, or working with a lower-quality screen resolution. Remember a simple rule. If your background is light, your text should be dark. If your background is dark, make your text light. 

Experts suggest choosing three colors and devoting 60% to the primary color, 30 percent to the secondary color, and 10% to the accent color. PowerPoint offers themes to help make this choice easier and that take light and dark presentation environments into consideration.

Use Animations Sparingly

Animation can be useful in making a presentation more dynamic, and help to emphasize points, but too much animation can be distracting.

Animations can add interest to your presentation and keep your viewers focused and paying attention. Don’t overdo it, though. Microsoft Support notes that “Presentation experts recommend using animations and sound effects sparingly. Animation can be useful in making a presentation more dynamic, and help to emphasize points, but too much animation can be distracting. Do not let animation and sound take the focus away from what you are saying.”

Use Keyboard Shortcuts

For the best quality PowerPoint recordings, take the time to learn and use PowerPoint keyboard shortcuts. This can let you seamlessly start your presentation and transition between slides.

Challenging Advanced Students With Differentiated instruction

“Differentiation has become a ubiquitous term and a much discussed concept in education.  Educators everywhere realize that students have diverse needs, and there has been a push to ensure that teachers are using strategies and supports to meet the needs of all students,” a report by Teachers Pay Teachers said. 

The same report found that more than 95% of educators view differentiated instruction as important to student achievement. Providing educational support to advanced learners not only engages students, but also more actively involves them in the learning process.

DIFFERENTIATING EDUCATION FOR HIGH-ACHIEVING LEARNERS

YuJa makes it easy for teachers to provide varied work to meet the needs of high-achieving students. 

Carol Tomlinson, an expert in the field of differentiated instruction, notes that “a chief objective of differentiated instruction is to take full advantage of every student’s ability to learn.” Differentiated instruction provides all students with learning opportunities they need, but can be especially helpful for advanced learners. 

Ideas to help challenge advanced students include:

• Offer more challenging work to students who already have the basic competencies. Students can work independently or in groups. 
• Offer a variety of assignment options. For instance, students could be offered the option of a PowerPoint presentation, an essay, a poster, or a video project.
• Break up classroom projects into different portions to allow students to focus on their strengths. Assign high achieving groups research tasks to increase their interest level.

Some of the top strategies for differentiation, according to the TpT report, include individual/small group instruction, leveled activities, scaffolded lessons, formative assessments, offering multiple learning styles, flexible timing, options to show learning and providing student choice. 

BUILDING SKILLS FOR HIGH ACHIEVERS

YuJa enables students to engage and interact to build new skills and maximize the educational experience. Some high-achieving students, while successful academically, may struggle with social engagement or have other challenges.

• Real-time discussions enable in-depth conversation about class topics, enabling students who may be less likely to speak up in class to engage online.
• Auto Captioning offers a readable and searchable transcript, facilitating learning for students who do best with visual, rather than auditory learning.
• Students who feel anxious in large group settings may find video presentations less stressful than in-person presentations.
