Having heard the recording of Queen Victoria, I got an impression that she used English of these days in terms of vocabualry and grammar considering she was a person of 17th century...And the same applies to Queen Alexandria of Denmark(Did she speak such a fluent English when she were alive?)

What might be the possible explanation to this question?...Because souls speak with the help of live men on earth or because they have kept studying to mature their own sprituality in the afterlife....Or any other possibilities?...
