Am I making myself understood? это звучит нормально?

"Am I making myself understood?" sounds somewhat natural but feels off to me personally. This is probably because the phrase sounds similar to "Have I made myself clear?" which is commonly used by parents and teachers when they're reprimanding a child and have just told them what to do/not do.

Generally, if you're just asking if your conversation partner can understand you something like "Are you able to understand me alright?" or just "Can you understand me?" sound less rigid.

Or, if you're asking if they understand the topic, something like "Does that make sense?" or "Do you get what I'm saying?" might be more appropriate.
