How do I let the player read something during combat without it being distracting?

I've made a boss fight in my game where the boss speaks to the player in text visible in the top of the screen, however, it can either be distracting or ignored entirely. The fight is very fast paced, so although the text stays on the screen for a while, it is quite difficult to read without getting hit.

This text is quite important to the encounter, and I wouldn't want to remove it.

I've considered voice acting, but I only want to use it as a last resort since I would likely need to pay a good amount of money for decent voice acting.

It would also be possible to pause the entire fight, but that doesn't seem like a great option.

Do you have any ideas?

I would only put it between boss phases where there can be an obvious break or yes as you said use voice.

It does have a second phase, but without a pause in between. I'll try slowing time for a second, thanks for the idea.

Use speech bubbles and put them in the boss's mouth.

Thanks for the response. I'm already using something similar to speech bubbles and the bosses don't have mouths.
