Most effective way to teach yourself to sing at home?

Hey all, I’m new to this subreddit but I’ve been wanting to get into singing for a while. I feel like getting better at singing will help me not only with being better at music but also with speaking and enunciating. While I have been singing for a while on my own, I was wondering if there was any advice you guys could offer in terms of what I could do to take my singing to the next level?

Thanks!
