We have someone deaf on my team too. Text chat is the best way to do it. Often we'll screen share in addition to chatting on a client like Slack and that works well in my experience. We find live captions a bit hit and miss, but it helps when there's no alternative. Normally in addition to live captions we'll have someone add notes in chat too. I've never been diagnosed with anything officially but I have a stutter problem and I struggle to convert my thoughts to words in real-time. So even for someone like myself I find text preferable to voice/video meetings most of the time anyway. I suspect a lot of non-native speakers probably feel similar too. Video / voice meetings can be nice to do from time to time for casual meetings such as retrospectives, but when I need to explain something technical I'd rather have time to compile my thoughts and write them down in a way that's clear and easy to understand. Plus if I write it down it's stored on Slack for later reference and it's more accessible for those who struggle with audible communication.
