Instructional Continuity: Captioning for Live and Recorded Lectures
Any one of an array of events can disrupt faculty’s ability to teach courses via on-campus, in-class sessions. Cal Poly’s commitment to students includes making sure that we provide the opportunity to complete courses despite disruptions, whenever possible. Using captioning in synchronous and asynchronous teaching is inclusive of all learners as it supports access for students who are deaf or hard-of-hearing, visual learners, English Language Learners, and students with ADHD or learning disabilities. There are user-friendly and easy ways to do this. Below you will find resources and tutorials to get started.

As we transition to remote instruction, instructors may be delivering live lectures and presentations via ZOOM. Live lectures can create challenges for students in the online learning environment, and providing real-time captions can improve comprehension for many students. If a student who is deaf/hard of hearing has an accommodation need for live captioning, Disability Resource Center staff will notify their instructors via email, and coordinate with them to get a live captioning service in place. For the spring 2020 quarter, the DRC has provided students needing live captioning accommodation with their own Otter.ai accounts, so they can access live captions on their own.
Instructors may also be using Screencast-O-Matic, Camtasia, or ZOOM to record lectures or instructional videos to explain concepts, demonstrate processes, and illustrate complex ideas. Whichever tools and methods you choose, providing closed captions with your recorded videos ensures the best experience for your students.

Using captioning in synchronous and asynchronous teaching is inclusive of all learners as it supports access for students who are deaf or hard-of-hearing, visual learners, English Language Learners, and students with ADHD or learning disabilities, among others. There are some very user-friendly and easy ways to do this. Below you will find resources and tutorials to get started. We hope you will explore these options when you have time; and know you can reach out to us for help at any time.
You can record your live lectures to the cloud, and select options in your ZOOM settings that will make it easy to create automatic transcripts and closed captions after the recording is posted. This is especially important for students who are deaf/hard of hearing, and also for students who may have missed the lecture, and students who rely on captions as a study aid.The following resources can help you select your ZOOM settings before you begin your live lectures:
- ZOOM: Automatically Transcribe Cloud Recordings (for closed captions for recordings)
- ZOOM: Getting Started with Closed Captioning (for live captioning) (use this option if you have a third party who can create the live transcription)
- Change your Language on ZOOM (helpful for World Language instructors)

TIPS TO GET STARTED
- Regardless of which option you choose for delivering lectures,a good microphone is key for the best possible speech recognition accuracy. Samson Go mic is usually available on Amazon for around $30. If you plan to record at your laptop, you may be able to get by with simply using the web cam's microphone. But if you plan to walk around, you'll get better results with a microphone like the Samson Go mic or by wearing a wireless mic.
- Verbally describe content in the slides or screens you are sharing with students. Sometimes there is degradation of video quality during screen shares, so this practice is especially important for online instruction.
- Allow students to ask questions in Zoom's chat interface; instructors should get in the habit of repeating those questions for all students attending via Zoom, as there may be some students who can't see the questions.
ZOOM: Options for live (real-time) captioning
Video Demo from Otter team: Live transcribe Zoom meetings with Otter for Teams (must have a Team account)
Video Demo for Cal Poly users: Using Otter Teams account with Zoom for Live Captioning (must have a Team account)
Video Demo for Cal Poly users: Using Otter free account with Zoom for Live Captioning (to use with a free account)
Otter.ai has an excellent live captioning feature. Cal Poly DRC purchased temporary licenses to be used by Deaf and Hard of Hearing DRC students during class for real-time captioning of lectures for spring quarter. Instructors can use Otter as well by creating your own account, that includes a free version with limited minutes. Then you can use Otter with ZOOM to provide live captions during a ZOOM lecture for all of your students. To do this, just open two windows, side by side, to display your presentation on the left side, and the Otter live transcription on the right side. Now all students can follow along. Alternately, you can share the Otter link with your students directly, so they can follow along on their own devices if they wish. Additionally, Otter can provide transcripts for audio recordings such as podcasts and interviews.
Otter pricing plans
Otter pricing plans include a free version (600 minutes of transcription per month; about 10 hours, which translates to about 10 class sessions) that allows you to upload an audio recording to Otter, which will transcribe the audio and allow you to easily correct mistakes (the audio playback is synchronized with the text so you can see exactly where it makes a mistake). This is a huge time-saver for transcription.
For the spring quarter, there is an educational discount for Otter Premium: $4.99/month for 6,000 minutes (100 hours) of free transcription. The Premium version also allows you export a .SRT (caption file) that can be uploaded with the video to YouTube for captioning purposes. Or convert the .SRT to a .VTT for those who use Vimeo.
For the spring quarter, Otter is allowing Cal Poly 10 licenses per team/department for a free 2-month COVID trial of Otter for Teams (the Enterprise version). You can select this link to redeem those free trial licenses of Otter for Teams licenses: https://otter.ai/purchase/team?code=COVID19. No credit card is required. You just need to indicate how many licenses you want, (we recommend 10 unless you know that your department won't need to use that many). Then create the account and click the start free trial button. Each department should designate one person to be the admin who signs up for the free trial, and then that person can dole out licenses to others in the department as needed.
Otter and accents
Otter speech recognition recognizes a wide range of accents with English spoken as second language. They are leading in the industry with transcription with heavy accents, transcribing in noisy environments, and real-time transcription speed.
PRESENTATION TRANSLATOR FOR POWERPOINT
Presentation Translator for PowerPoint provides an easy option to have the subtitles feature turned on, but not displayed for everyone, so individual students can choose to view them on their personal devices. DRC recommends all instructors using PowerPoint should at least turn on subtitles, then they can decide if they want to show them automatically to all students or let individual students decide if they want to see them on their own devices. Presentation Translator automatically creates a QR code and link that an instructor can share with their students at the beginning of the presentation. The link allows students to see the subtitles live on their own devices in addition to seeing the subtitles on the PowerPoint during the lecture. Students who have never used this before might try it and find it helpful. This is an easy way to promote inclusion in the online environment.
Presentation Translator Languages
Presentation Translator allows a speaker (e.g., instructor) to speak in any of the 10 supported speech languages – Arabic, Chinese (Mandarin), English, French, German, Italian, Japanese, Portuguese, Russian and Spanish – and subtitle into any one of the 60+ text translation languages. This could be helpful for world language instructors who are teaching any one of the 10 supported dictation languages above. (Otter currently only supports English.) So when it comes to using one of these tools for live captioning, world language instructors are better off using Presentation Translator.

- For PC: Microsoft's Presentation Translator is a free add-on for PowerPoint (Windows software version only at this time). If it's not already in your software version of PowerPoint, you can download it here: https://www.microsoft.com/en-us/download/details.aspx?id=55024
- For Mac: If you use a Mac, the Presentation Translator feature is built into the Office 365 (online) version of PowerPoint: Present with real time automatic captions or subtitles in PowerPoint.
Google Slides live captioning: When you present Google Slides, you can turn on automatic captions to display the speaker's words in real time. This feature is available on Chrome devices in U.S. English.
Microsoft Teams also offers live captioning. With live captions, Teams can detect what’s said in a meeting, and present real-time captions for anyone who wants them.
Closed Captioning for Asynchronous (Recorded) Presentations
Instructors can record lectures and screencasts with Screencast-O-Matic, Camtasia, or ZOOM. We recommend Screencast-O-Matic due to its ease of use and editing features. Videos can be hosted on these sites, or in YouTube, Vimeo, or Microsoft Stream. All of the above options include settings for generating automatic captions for recordings, that can be edited to correct inaccuracies and add punctuation. You can then link or embed your video in Canvas or PolyLearn. Find options below.

Captioning Videos Created by Others
CAL POLY CAPTIONING SERVICES
If someone else created a video you wish to use in class, such as a public video on YouTube, you cannot correct the captions or even turn on automatic captions if the video creator did not do so themselves, and did not provide you with editing access. If you don’t have access to a video to caption it (including non-YouTube videos), please visit Classroom Technologies Media Captioning page (Links to an external site.) and scroll down to Automatic Sync Technologies (AST). AST can caption online videos with the use of their "smart player,” a media player that synchronizes the URL of an online video with an AST caption file in order to present a captioned version of the online media, which you can place in Canvas or play in class. Lead time is 2 weeks, so make your requests well in advance of showing your video in class.
Additionally, if you want to pay AST for your own captioning services, you can still receive the CSU discount by completing this form: CaptionSync CSU System Account Sign Up. Once you complete the form, it is sent to Classroom Technologies admin for approval. Then you can submit your own videos, and they will be billed to you. You can ask what the lead time is for captioning; it is usually a few days.
Rev.com: This video captioning service provides caption files for videos that you have created, or public videos that allow you to create captions. Turn around time is 24 hours; cost is $1 per minute. You can then upload the captions to YouTube, or another hosting site such as Screencast.com, for quick captioning. Please note that many public YouTube videos do not allow others to provide captions, so check first before using Rev.com for videos created by others.
