He has no one to turn to.

What does 'to turn to' mean?

Thanks in advance!
to turn to for support, to go for help
'to talk to' is more specific than the full meaning of 'to turn to'.
The support that is needed can come in the form of talking, but it doesn't have to be talking.

So if you change 'turn to' to 'talk to' you are limiting the meaning more.
