As people adjust to remote working and self-isolation from Covid-19, the need for accessible technology is even greater.

More than ever, people are relying on video conferencing technology to learn, work and socialise. Many users are rediscovering the power of video calling platforms. Others are learning how to use them for the first time to talk to family. But the rise in remote working and living is presenting barriers as well.

Mental health and loneliness during the Covid-19 outbreak is a concern. For people at home, audio and video conferencing can help reduce feelings of isolation. Government advice recommends keeping in touch with loved ones online for your mental health and wellbeing.

Video calling services like Zoom, Teams and Google Hangouts have all seen a spike in usage since the Covid-19 pandemic. Microsoft Teams has seen a 775% rise in users in Italy alone as a result of Covid-19. As a response, many have offered free versions of their premium tools to help people keep in touch.

But with so many services available to help, it can be hard to know where to start.

Who this guide is for

People with access requirements

The nature of video calling means that it disproportionately affects people with sensory impairments like deafness or hearing loss. We hope this guide will be useful for deaf and hearing-impaired people who want to find the best video conferencing platform to work or socialise.

People with elderly relatives

It may also be useful for people wanting to keep in touch with elderly relatives more easily. Elderly people with hearing loss may benefit from live captions and other practical features like ease of setup.

Businesses and organisations

It may be useful to businesses who want to make their video conferences as inclusive as possible. Especially for students or colleagues who are deaf or hearing-impaired, though it’s worth noting that captions benefit many people. They can provide a better experience for people with developmental disabilities like attention deficit hyperactivity disorder (ADHD) and autism. They can also help understanding for people whose native language is not English.

Every person with access requirements will have their own individual needs. It’s always better to ask what they would prefer instead of assuming.

What are Live Captions?

When we refer to live video captions throughout this guide, we mean automatically transcribed closed captions that appear on the screen as people talk. Also called subtitles, live subtitles, closed captions and automatic video captions.

As with any artificial intelligence (AI) technology, live captions have limitations. Often they are not perfect, and the quality varies according to the provider.

Some platforms have better captions than others, whereas some don’t offer it at all. Often, when the functionality does exist, like in Microsoft Teams, many people don’t know how to turn them on. Even for the tech giants, there is inconsistency as to which of their products have live captioning capabilities and which do not. We’d like to see more businesses sharing this technology and licensing it to others.

Live captions work best for one to one meetings or small group conversations. They will become less accurate if more people, voices and noise are added to the call. Automated caption technology often struggles to pick up strong accents and speech impairments too.

But they can be helpful for people who are hearing-impaired, deaf or elderly. They also help improve understanding for non-native English speakers.

Video conferencing apps and services

Most video calling apps offer the same basic features. A screen-sharing option to let other callers see what’s on your computer, a mute button and instant messaging. But they differ in the access services they provide, like live captions. And how readily they make those services available.

Below you will find an overview of the main video conferencing services and the functionality they offer.

Google Duo

Free to use, enables one-to-one video and voice calls and it works across both iOS and Android devices unlike Apple’s FaceTime. Group calling limit is 12. Ability to send and receive video and audio messages. Google Duo seems to be preparing live caption functionality at the minute.

Workarounds to get live captions for video calls

There are some apps that will give you live transcriptions of what is being said around you. These apps can be used in conjunction with other video conferencing software and may work well in one-to-one video meetings or small group chats.

Live transcription apps and software

Some apps are limited in what they can transcribe. But the technology is always improving so it’s worth checking for new apps and updating the ones you use.

  • Live Caption, free, easy-to-use app which transcribes speech in real-time. Users can upgrade to Live Caption Unlimited to keep listening for longer than 60 seconds, without being interrupted for $2.99 per month. Available on iOS only.
  • Roger Voice, basic free service which adds captions to voice calls in real-time when using the app. Users can upgrade to £5.49 per month subscription plan or unlimited package for £27.49 per month. Both packages allow calls to landline and mobile numbers but vary on the number of minutes offered. Available on iOS and Android.
  • Google Live Transcribe for Android offers real-time transcription of speech and sound to text on your screen.
  • Otter focuses on meetings transcription but it also transcribes conversations. Available on iOS and Android.
  • Just Press Record app for iOS transcribes audio recordings, such as lectures, talks or meetings.

Live caption by Google is an integrated feature on selected Android phones and the Google Pixel 4, 3a, 3 and 2 models. It transcribes everything it can hear, from speech to podcasts and videos.

Sound amplifiers

Some apps are available to help you hear what’s happening around you more clearly. This might be by reducing background noise or boosting the sounds you want to hear.

You can find more technology advice in Scope’s guide to apps that make life more accessible.

Tips for better video calls

Whether you’re video calling for work, or to keep in touch with family, there are ways to get the most out of your video conferencing technology. Follow these tips to make your video meetings more accessible and inclusive.

Remove background noise
For example by turning off the radio, muting the television or going to a quiet room if there are others in the house.

When using live captions, speak clearly with a natural flow

It may seem intuitive to speak more slowly as you wait for the words to appear on the screen. But AI technology is generally trained to hear natural, flowing speech. This also depends on the provider.

And if one person on the call relies on live captions, it’s a good idea to ask everyone to turn them on, too. If a person is speaking too quietly or too fast and can see that the captions are not appearing properly, they can see how to adjust their speech.

Use a good, external microphone if possible
The audio output is much higher than built-in microphones found in a computer or mobile. Using an external microphone will improve the sound quality for everyone else on the call.

Sit close to the microphone
This allows automated caption technology to pick up your words more clearly.

Make sure you have a good internet connection
This is important for high video and audio quality. Sit closer to the WiFi router, or consider purchasing a WiFi extender to improve your internet connection.

Headphones and headsets improve the sound quality for everyone
If all call participants can use headphones, the better the experience will be. Many new headphones have a built-in microphone too, which will make your audio output clearer.

Ask everyone to mute their mics when they are not speaking
This will help reduce unwanted noise.

Take your video call in a well-lit environment
This helps makes facial expressions clearer for everyone, but also for people who are hearing-impaired, signing or lip-reading.

Digital phone services provide higher quality sound than phone networks
Even if your phone network signal is good, calls through WhatsApp, Facetime or Skype will generally offer higher quality audio.

This is because regular analogue phone calls compress the sound to a limited part of the audio spectrum. Digital calls compress sound differently, allowing you to hear everything in clearer detail.

Mobile 4G and 5G data is better than most home WiFis
The service tends to be better for video conferencing, but more expensive.

If sharing a presentation for work, send the slides and speaker notes over before the call so people can read along.
