Finnish has highly regular pronunciation with almost 1-to-1 correspondance between letters and sounds. In the first clip English is read as if it was Finnish, using Finnish pronunciation rules. Works pretty well as Finnish would be pronounced correctly and for Finnish speaker it's quite easy to catch Finnish pronunciations of foreign words.

No. without reopening the article, I thought one was Finnish read with an English accent. This was due to what the author had grown accustomed. In his youth screen readers did not have as many options?

I think it was the opposite - English read with a Finnish accent.

It's not just an accent. It's reading the words as if they were Finnish, so totally different.
