Top Two Letter Combinations in Words 17wpm

There is a slight pause before the answer is spoken, which is just enough time to say the letters out loud with ICR (Instant Character Recognition). These are the top two-letter combinations found in words. For each combination, try to head-copy it. First, the letter combination is sent in Morse code. Then it is spoken. And finally, it is sent again in Morse code. If you missed it the first time when it was sent, the second time allows you an opportunity to learn the words. These letter combinations were located by analyzing 600 public domain books made available from Project Gutenberg. Once all the letter combinations were identified and tallied up, I selected the top 300 combinations as a reasonable number to assist in transitioning from copying individual letters to entire words. 73 de AD0WE!
