You could look for coaches who train actors AND singers. But my coach trains singers primarily, and it seems to me that the techniques are the same. I wanted to work on my enunciation as well, in addition to loudness, cadence, nasality etc. My speaking style is staccato, and I emphasise too many words. That she corrected by telling me to read from a fully prepared script if I could help it, which is useful for recordings in these times! That got rid of the staccato, because my low-bitrate brain was freed from having to figure out what clever thing to say next :) Then to work on the cadence, I had to underline at most two words per line, which would most effectively deliver the import of that line. Finally, breath control. "Speaking from the diaphragm" is a real thing. There's a daily regimen of vocalization and breathing exercises that I do. My neighbors look at me oddly. But these exercises do help. Good breath control allows you to deliver a long line, with appropriate pauses and cadence, without feeling your tank is going to empty soon.
