Webinar Transcription

As I mentioned, we'll be covering live captions for Zoom webinars today. In the beginning, we'll go over a quick couple of slides of who is Rev, what we do, for those of you who may not be familiar. Then we'll go over the benefits of live captions. And then we'll actually jump into a live demo of how to get set up with live captions for Zoom webinars, and then close out with a Q&A session at the end covering any questions that you guys may have along this time.
So before we begin, who is Rev? Rev is a provider of on-demand transcription, closed-caption and subtitling services. We have over 100,000 customers. Everything from your global enterprises, to freelance journalists and YouTubers, and everybody in between. If you're making video or audio content, it's highly likely that you have a use for Rev or have already used us.
We have a network of over 40,000 transcriptionists and translators that have transcribed more than 100 million minutes of audio and video for companies like Google, Facebook and the like. As I mentioned before, captions and subtitles, primary use cases here are accessibility and compliance, taking the spoken word and making it visual on videos or translating it into foreign languages to unlock new audiences, or for localization as well as transcripts, which makes it easier to search and use video and audio. So if you're like a video editor and you want to be able to edit your content faster, you can now search through all of your raw footage, or if you're a market research firm and you want to find key insights from the interviews that you've conducted across a wide array of interviews, that's another very popular use case for transcription.

So kind of how we ended up here talking about Zoom in general, is largely due to COVID, as probably most of you are aware, right? I know I didn't use Zoom nearly as much before the pandemic started, prominently only for business meetings; and that has vastly changed. Right now, you are doing webinars, you're talking to your family across state lines, you might even be going to church services or college classes virtually, which is a very different world than we're in a couple of months ago.
This chart from ZoomInfo shows that. We're seeing 87% growth in the video conferencing space since January of 2020 and that is massive. As we kind of saw, these spikes in popularity and usage for web conferencing software, we realized that we maybe didn't have a great solution to help our customers and users be successful and be accessible through these platforms.
So we started to look at what were the most popular web conferencing softwares, and what was there available to suit your needs; and it became very clear that Zoom was the front runner, the highest adopted web conferencing service out there. So from that point, we started working on live captions for Zoom meetings, and this was released, I believe on, I have it right here, June 25th.
So if you go to rev.com, you go to our services drop down and you click on live captions for Zoom, you can actually use the same captions that I have on this webinar for your meetings. People started adopting that and using it, and largely, the feedback has been awesome, which is exactly what we're hoping for.

Danny Lambert
But at the same vein, we realized that we didn't have a solution for webinars customers and also probably didn't recognize how large of a need that is. And so as the requests started rolling in for webinar live captions to help make that content accessible as well, we started digging in and finding ways that we could make that available for the companies and users who are leveraging Zoom webinars.
So before we hop into what are the benefits of adding it and how we actually go about adding live captions to our Zoom webinars, I think it's interesting to talk about how we actually generate this. If you've been using Rev for a long time, you're probably very familiar with our human captions and transcriptions where you submit a file and then there's actually a transcriptionist or a translator on the other side, taking that video and audio and converting it into text.
The live captions that you're seeing on the screen are actually done through our Automated Speech Recognition Engine or ASR. And all that is, is it takes audio and video and automatically generates captions and transcripts. So that's how we're able to render this onscreen so quickly is it takes what I'm saying, sends it to our speech recognition engine and then sends back a caption or a transcript.
Largely how the accuracy of this is measured, how the efficiency of an ASR engine is measured is on Word Error Rates. Like what percentage of words has errors in them essentially? And we were tested up against Google, Microsoft, Amazon, and Speechmatics, and came back with the lowest word error rate amongst all of those major players, which is really, really awesome; and as you can see for yourself, pretty high performing in a stress test setting.

Danny Lambert
The way that people have been using the speech recognition before it was available for Zoom is we'd have the companies leverage our API and build it into products that you might already be using where there's transcripts and captions and you might not even know that it's powered by Rev. We also have the auto TC service, the automated transcription service, which is powered by ASR; and this is just another solution that we're putting out into market of ways that you can leverage the ASR engine to get transcripts and captions back fast and accurately.
As far as the major benefits, accessibility is the biggest one. Right? If you're creating really good content, you're putting all this effort into it, it should be accessible to everyone who's visualizing it either live or recorded. So by far, accessibility is the mainstay here for live captions for webinars, but also equally interesting is the attendee experience. Right? The engagement, the recall on content is much better when you can hear it and you can see it, especially for distracted learners. Right?
There's many of us who are at home with kids pulling on our pants, or you have a lawnmower going on outside. The ability to read alongside what's being said really helps with recall and attention and maintaining focus on the content, especially over long periods of time.

So I did record this live demo of how you can actually get set up with it. I had to record it because I'm on my Zoom webinar account right now. So I couldn't actually go through the Zoom webinar account set up. So what I would advise during this time is to disable your live captions for this webinar, because the video I'm going to show already has captions on it. Up to you, but it will probably make the experience a little bit better.

Danny Lambert
Good morning, everybody. This is Danny Lambert, and I work on the marketing team here at Rev. In today's demo, we're going to be walking you through how to use Zoom live captions for webinars, how you can get access to them, how you can add them to your events, and ultimately what they look like. So I'll run through a little bit of what you need to get set up, how you can get access and actually jump into the meat and potatoes, which is what this looks like.
So the prerequisites to being able to use this is first to have a Zoom webinar account. If you don't use Zoom webinars, this probably won't be very relevant to you; but if you do, that's the first and foremost most important aspect of using this feature.
Second is to make sure that your Zoom account admin also has a Rev account. They're going to need to authorize their Rev account to be able to use live captions for Zoom webinars. So you want to make sure that the Zoom admin also has a rev.com account.
And the third is to make sure you've requested and ultimately been granted access to the beta program. So at the end of this, we'll show you how you can request access for this feature. And then, as we get around to enabling more and more people into the beta feature, you'll be notified that you've been granted access and then everything that you'll be shown today will be available to you.
Once we get started here in a second, we're going to run through each of these steps for how to actually get set up using live captions for doing webinars.

Danny Lambert
The first step in this series, which we actually won't be going through. we have some documentation we can send to your admin, is to get your Zoom admin set up organized. There's two steps just enabling a live streaming on your webinars. That's the only step in this series that we won't be covering in this demo.
From there, all you need to do is create a Zoom webinar event, generate a streaming key, essentially take those streaming keys and enable webinars on your event using those keys that were generated and then host your webinar. It's really a couple step process; it's very simple and we're actually about to walk through that live here right now.
So the first step is to go into your Zoom account and then go down to webinars. From here, you'll click schedule a webinar. I'm going to name my test webinar, and then I'm not going to worry about any of these other details right now. These are unique to each individual person's event. So it wouldn't really be relevant for me to fill these out. We'll just go ahead and schedule that.
At this point, you would have access to this Zoom webinar live streaming URL creator. Once you're granted access to the beta, you'll be given this link and this is what generates those streaming keys that I talked about in the third step here. So I've already created my webinar. Now I want to generate those streaming keys. So how you would go about doing that is within your webinar event, you would click start this webinar and open your Zoom account.
From here, you'll see a closed caption option and you just need to click the copy of the API token. So I click that and I go back to the API key generator and I drop that in and I'll go ahead and click get live streaming URL. And there's a generated streaming URL and a streaming key. At this point, you can go back to that event and close it out. We don't actually need that at this moment.

Danny Lambert
So back within your webinar account, I'm back onto the test webinar. All I need to do is come down to the bottom session and go all the way over to the right and click live streaming. From here, you click add a service and you start copying and pasting over those values. So I'll take that stream URL and I'll drop that in. I'll take that stream key and I'll drop that in. And then for the live streaming page URL, I always just use the URL of our company's home page. So I'm drop in the Rev. com address and I will click save.
So at this point, we've already gone through steps one that your admin did, two, three and four. At this point, all you have left to do is actually host the webinar event and enable the live captions on it. So I'm going to go ahead and pretend that this is the day of the event, and I want to start streaming the live captions to my webinars.
So you would go into the webinar again, the day of. It would open everything back up, and then all you need to do is come to more and then click live on custom live streaming service. This will pop up this new window that essentially is preparing the live stream for your webinar. This may take a few seconds to complete.
Now I can close that out and go back to my event and you'll see webinar is now streaming live on custom live streaming service, and you will start to see the captions pop up on the bottom of your screen. As for each of your participants in the webinar, they'll have the ability in the bottom corner here to come in and toggle on and off these captions as they see fit. That's how they access them or turn them off. But essentially what you're seeing at the bottom of my screen now is the same thing that all of your webinar participants will be able to see once you have live captions enabled.

Danny Lambert
I'll close out of that, and that's essentially all there is to it. You make sure that you have access to the beta. You get your Zoom admin to set up the settings that I have documented, and I can share with you, you create a webinar, generate the streaming key; you associate those keys with the live event, and then you just host it. It's as simple as that.
Hopefully, this is very helpful. Look forward to hearing your questions on how to get started with Rev Live Captions for Zoom Webinars. Thank you.
Awesome. Pop back in here. Great. So before we hop into questions, I saw a whole bunch of them come in while I was talking and also during that video, I'm sure one of the questions many of you have right now is, "Hey, that looks super cool. I would love to have access to that."
So, I mentioned it briefly in the video, but if you're looking to gain access to the live captions for webinar beta program, it's very quick three step process. So you go to this URL right here, enterprise.rev.com/zlc-webinar. I'm going to leave this up for a second. It'll also be included in the followup materials, but when you go to that URL, there'll be a form at the bottom that just ask for your email, a couple of questions about your webinar usage, and then we will receive your request.
It'll get reviewed by our team and they will grant your user access. And then you'll receive a followup email that says, Hey, you've been granted access to the beta program. Here are the instructions on how you can get set up. And those instructions very much just mirror what I showed you in the demo a second ago. So if you want to get set up again, it's enterprise.rev.com/zlc-webinar, and then you should expect a response from someone on our team in a pretty quick, quick timeframe. So I'm going to go ahead and stop sharing my screen now and try to get to some of these questions that came in.

Danny Lambert
Perfect. Okay. First question. From Susan. You might've already answered this during your presentation, but does the live captions also work on Zoom meetings? Not just Zoom webinars. A good question. I can actually show you where you can access this, Susan. I mentioned a little bit earlier on, but it is a very good question.
We released Zoom captions or live captions for Zoom meetings back in June. And you can self sign up for that on the Rev website today. So I'll actually show where you can go about doing that. You go to rev.com. Under services, there's an option now for live captions for Zoom. Currently, this is only applicable to meetings, but if you wanted to try and add live captions to your Zoom meetings, you could start a free trial here and just go through a self service set up flow in your Rev account and enable that for meetings. So yes, that does exist.
Andrea, will the recording be available for future reference? Yes. This will all be sent out in an email one to two days following the event, including the recording and the deck.
Jonathan, I think I saw a couple of questions about the lag time. The lag time is primarily due to the fact that this isn't prerecorded. So all of the audio that's going in, it's being processed in real time, so there will always be a little bit of a lag and that is something that the product team is always working on, but it's just inevitable in a live streaming scenario; is this isn't prerecorded captions and the machine learning algorithm has to actually process what I'm saying.
Eric asked, "Do you have your own language understanding engine or are you using a third party?" We built this ourselves. It is Rev AI. I think I covered it a little bit earlier in the deck so when I share that out, please feel free to reference it. If you go to Rev.ai, you can actually learn all about the speech recognition engine that we've built that is powering this.

Danny Lambert
Robin asked, "If you record the Zoom, are captions included and can you edit the captions after the fact?" So currently, the captions are only for live streaming. So when I end this event, I will not get a recorded video with the captions included. You would still need to put the recording of this, place a Rev order for captions. Not sure if that's something that we'll be able to work on or bake into the product in the future, but currently the captions will not be associated with the recording of the live stream.
Angela asking, "How does this work slash appear with multiple speakers?" So if we have multiple speakers, it will appear like you're seeing here. It won't explicitly, at the moment, call out the individual speakers name, like a speaker diarization. Again, I think that's something that we are working on. It will provide the captioned content. It just won't explicitly call out, you know, if this is Danny speaking versus speaker B.
Scott asked, "Can you stream on custom live streaming services and Facebook live at the same time?" Very good question, Scott. At the moment, you are not able to, so where you go and add the streaming key and the demo essentially replaces the ability to livestream to Facebook or to YouTube at the moment. I know this is something that has come up from a couple other Rev users as a point of concern or something that they're interested in seeing us have in the future. So the answer is currently no, but it might be something that's available in the near future.
Richard's question at the bottom is, "In both webinar and meeting applications, will the captions be available as a TXT file?" So the short answer to this is yes, there is an option within your webinar account where you can click save captions. And essentially what it will do is at the very end, it will spit out a very raw, like actual recording, TXT file, everything that was covered. At the moment, it's not very usable. I wouldn't go using that file for anything other than just reference of the event; it's still not on par with what it would be like if you went and ordered an actual caption or a transcript file.

Danny Lambert
Okay. Going into the chat now, I see there's a lot here. Sorry, guys; there's a lot to get through. I hope I'm answering your questions in a suitable manner.
Trying to get through all the chat. My apologies.
I'm not seeing anything that I haven't already answered. I'm sure I am missing some and I apologize for that. So, if I didn't get to your question during the Q and A, my email is danny@rev.com. Please do not hesitate to reach out. I will answer your questions. I love to hear your feedback. And again, it's just a lot of chat coming through so it's a little bit hard for me to see which ones are comments versus questions in which ones I may have missed.
So, as I mentioned, my email is danny@rev.com. If I didn't get to your question, please follow up. This will all be sent out in one to two days. So you can have this for reference. And if you want to sign up for that beta, it's enterprise.rev.com/zlc-webinar. So thank you guys so much for attending. I really appreciate you coming out. And if you have any questions, please don't hesitate to follow up. Have a great day, everyone.
