"Know who is that person" vs "know who that person is"

2

Is it:

I would like to know who is that person he is speaking to.

or:

I would like to know who that person he is speaking to is.

I am confused as to which sentence structure is grammatically accurate. Or are both sentences correct?

1The first one is wrong since it exhibits subject-auxiliary inversion, which subordinate interrogative clauses (aka embedded questions) do not normally have. The meaning is "I would like to know the answer to the question 'Who is that person he is speaking to?'" – BillJ – 2017-01-02T10:50:57.707

@BillJ But such sentences are grammatical for some speakers - at least according to CamGEL ... – Araucaria - Not here any more. – 2017-01-02T13:27:16.820
