Can we attain fluent speech if we practice everyday for a year?

Can we attain fluent speech if we practice everyday for a year? Hi, I'm 21M and recently started doing all these exercises that will probably help me gain fluency (hopefully) like breathing techniques and jaw exercises. I do them everyday for about 40 mins and read aloud in front of a mirror 🪞. And I will also be going for Speech Therapy in a few months I just wanna ask will all this help me? Like have you or anyone you know who has done all this and gained fluency? And what happens if we gain fluency once? Do we continue the same cycle for the rest of our lives?? Pls guide me 😊
