My middle-school aged kids explained the difference between cooked and cookin' to me the other day, and now they really get to roll their eyes when I intentionally use them in as corny ways as possible.
Bonus points for coming with other, terrible, slang. You can really get a cringe if you say something like "Chat, we're cookin' now - I'm all rizzed up”
When I play wrestling video games at night, I turn off commentary and just do it myself. My daughter walked in on me and was looking at me like I was nuts
I tried streaming for the first time over the weekend. Damn is it hard to keep talking for multiple hours straight. Especially when there's zero messages in the chat. Streamers make it look normal but damn is it not
Get a producer or anyone with you and talk to them. That's how radio and TV broadcasters used to do it. They would talk to the console or camera operator. Eventually it becomes natural to talk by yourself. It does look like unhinged behavior without the context. But it is an old skill, as old as radio broadcast. Try acting monologues to yourself, it also helps.
But why? If you don't enjoy it, why try to get into streaming? The chances that it'll pay back for itself are incredibly small and it takes years of consistent streaming to get any kind of consistent audience.
If you do enjoy it, then by all means, practice a bit so it gets more natural (and more enjoyable).
If you learn your ways of speech from streamers and YouTube videos, and all of them talk in 2nd person to their audience, then your learned language will sound very similar to the English you listened to.
I have thought about showing off my gigantic single player creative mode Minecraft map through a live stream for years, I spent most of my free time over a decade of manually just building huge, huge structures.
And pretending to show it off to a live stream, talking about it and explaining it makes it easier to remember what/why/how I built stuff...
Anon should just do a stream and do their best and hope one of the popular streamers/youtubers pity them and give them a donation and a shoutout to a massive audience.
