Built-in far-field microphone

No TV mic

This model has no built-in far-field microphone — voice control goes through the remote.

Samsung's UK 2023 user manual, which covers the CU7 series, says the microphone switch on the TV is "supported only in" its QN, Q7, Q8, S8 and S9 series, which leaves out the CU7100. Samsung UK's CU7100 pages have no far-field voice row.
