Morse code thus determines the dot length. It is common to assume that a word is 5 characters long. There are two common typical words: "PARIS" and "CODEX". PARIS mimics a word rate that is typical of natural language words and reflects the benefits of Morse code's shorter code durations for common characters such as "e" and "t". CODEX offers a word rate that is typical of 5-letter code groups (sequences of random letters). Using the word PARIS as a standard, the number of dot units is 50 and a simple calculation shows that the dot length at 20 words per minute
Naming conventions of the International Phonetic Alphabet Naming conventions of the International Phonetic Alphabet The International Phonetic Alphabet (IPA) requires specific names for the symbols and diacritics used in the alphabet. It is often desirable to distinguish an IPA symbol from the sound it is intended to represent, since there is not a one-to-one correspondence between symbol and sound in broad transcription. The symbol's names and phonetic descriptions are described in the "Handbook of the International Phonetic Association". The symbols also have nonce names in the Unicode standard. In some cases, the Unicode names and the IPA names do not agree. For example, IPA calls "epsilon", but
