Slack voice is a way to talk to people through a computer or phone like you are on the phone with them. It's like you can talk to your friends or coworkers without needing to be in the same room as them. You just need to use a special app called Slack to do it.
When you use Slack voice, you can hear the other person talking and they can hear you too, just like a regular phone call. But instead of using your regular phone, you do it on your computer or phone with the special app.
You can use Slack voice to talk to anyone who is using Slack, whether they are in the same building or in another country! It's a great way to communicate with people when you can't be with them in person.
So if you want to talk to someone far away or just don't feel like typing out a long message, give Slack voice a try!
