I'm self training and i'm making progress i think but does anyone have a list of sentences that are good practice and like can test certain pronunciations and stuff? or just anything i can say to myself because i always have the problem of "what do i say?" i don't know. So just any help on goo sentences to use?

I used to just read books out loud.

Sometimes my voice will wander off pitch or the resonance will be off....the phrase "all of us" seems to lock it right back on again.

I am sure everyone ends up with little "calibration" phrases / routines.
