Ted Williams -- the homeless man with the golden voice -- was detained by LAPD last night after getting into a shouting match with one of his daughters.

It went down at the Renaissance Hotel in Hollywood -- where Ted and his daughter got into it so loudly ... a hotel employee called the cops.
Ted and his daughter were both taken to the Hollywood station, but neither Ted nor his daughter wanted to press charges so both were released.
UPDATE: Ted Williams enters rehab.
