What do you mean taking breaths? Like you struggle with keeping your head down while swimming and basically gasp for air the whole time like tarzan swimming/doggy paddle or you're front crawling/free-styling and cant help but breathe every stroke?
(I swam 2nd to 12th grade competitively,not using it as a chance to brag, more or less give some help)
I don't know how old you are but like all things once you get to a certain age your "baseline" is pretty much set. Drills and training can help but ultimately you may be stuck with a variation of what you have.
The beginning of each season on the team was a cardio workout to the max. Long distance, long distance, and even longer distances. It's nothing to train from 4-500 yd sets followed up by a rest with 7-800 yd sets after that. Long distance lung capacity is huge. The first few days are burners but the next few get easier quickly.
If you have a kickboard try holding it out in front of you as far as you can with the arm you don't normally breathe with. In my case I'm right handed and thus inclined to breathe on my right arm stroke. Try to swim down the pool only breathing to one side and holding onto the board with your opposite arm. After your breath put both hands on the board and kick for a few seconds, going to be dependant on how comfortable you are in the pool.
That's one drill you can do. It's going to be hard to slow down at first without gasping but ultimately its about cardio and forcing your body to be more efficient with the same amount of air. It's also going to improve your form for front crawl.
Suprisingly another great way to train is to do sprints. We always trained to do sprints with the least amount of breaths. Every time you turn your head you slow down due to drag, again forcing your body to go anaerobic.
Another thing we used for lung capacity was doing a "Silver Dollar". At the beginning of each season we started off with our coach throwing quarters in the deep end of the pool (that time 12ft). We'd swim from the shallow end, down the transition to the deep end, grab a quarter or however many we could handle, swim to the end. All under water, 25 yd pool. What you brought up was yours to "keep". (We could buy ourselves shorter practices if we got enough). Then we just slowly swam back to the starting wall. Sometimes I swore I was going to pass out but again, it gets easier the more you do it.
Lotta rambling, if I didn't make sense let me know.
