average number of words read in a minute
Words per minute Research done in 2012[15] measured the speed at which subjects read a text aloud, and found the average speed across 17 different languages to be 184±29 WPM or 863±234 CPM. However, for the languages that use the Latin or Cyrillic alphabets, the number of WPM varied, as low as 161±18 for Finnish and as high as 228±30 for English. The reason for this is different word structures in each language (longer words in such languages as Finnish and shorter words in English). However, the number of characters per minute tends to be around 1000 for all the tested languages. For the tested Asian languages that use particular writing systems (Arabic, Hebrew, Chinese, Japanese) these numbers are lower.
Morse code Each Morse code symbol represents either a text character (letter or numeral) or a prosign and is represented by a unique sequence of dots and dashes. The duration of a dash is three times the duration of a dot. Each dot or dash is followed by a short silence, equal to the dot duration. The letters of a word are separated by a space equal to three dots (one dash), and the words are separated by a space equal to seven dots. The dot duration is the basic unit of time measurement in code transmission.[1] To increase the speed of the communication, the code was designed so that the length of each character in Morse varies approximately inversely to its frequency of occurrence in English. Thus the most common letter in English, the letter "E", has the shortest code, a single dot.
