Benjamin Franklin's phonetic alphabet

Benjamin Franklin's phonetic alphabet was Benjamin Franklin's proposal for a spelling reform of the English language. The alphabet was based on the Latin alphabet used in English.

The alphabet
Franklin modified the standard English alphabet by omitting the letters c, j, q, w, x, and y, and adding new letters to explicitly represent the open-mid back rounded [ɔ] and unrounded [ʌ] vowels, and the consonants sh [ʃ], ng [ŋ], dh [ð], and th [θ]. It was one of the earlier proposed spelling reforms to the English language. The alphabet consisted of 26 letters in the following order:

Other English phonemes are represented as follows:
 * is represented as hu (as in huɥi for why).
 * is represented as ɥi (as in ɥiz for eyes).
 * is represented Franklin’s letter ah as in A scheme for a new alphabet.svg (as in hFranklin’s letter ah as in A scheme for a new alphabet.svg for house).
 * is represented dFranklin’s letter sh as in A scheme for a new alphabet.svg  (as in edFranklin’s letter sh as in A scheme for a new alphabet.svg  for age).
 * , at the time more probably, is represented as ee or e (as in leet for late or kes for case).
 * is represented as eer (as in keer for care or Franklin’s letter dh as in A scheme for a new alphabet.svg for their).
 * and are represented as ɥr (as lɥrn for learn).
 * is represented as ii or i (as in ſtriim for stream).
 * is represented Franklin’s letter ah as in A scheme for a new alphabet.svgɥi (as in distrFranklin’s letter ah as in A scheme for a new alphabet.svgɥi for destroy).
 * is represented Franklin’s letter ah as in A scheme for a new alphabet.svg (as in fFranklin’s letter ah as in A scheme for a new alphabet.svg for forget).
 * , at the time separate, is represented or (as in kors for course).
 * is represented tFranklin’s letter sh as in A scheme for a new alphabet.svg (as in tFranklin’s letter sh as in A scheme for a new alphabet.svg for cheat).
 * is represented zFranklin’s letter sh as in A scheme for a new alphabet.svg (as in mezFranklin’s letter sh as in A scheme for a new alphabet.svgɥr for measure).
 * Unstressed vowels are generally represented by the letters used to represent their stressed equivalents. What today is considered a schwa is mostly represented with ɥ, although whenever spelled in standard English with a, Franklin maintains the symbol α.





Vowels
Franklin's proposed alphabet included seven letters to represent vowels. This set consisted of two new letters, in addition to five letters from the existing English alphabet: α, e, i, o, u. The first new letter was formed as a ligature of the letters o and α – – and used to represent a sound that is roughly  as transcribed in the International Phonetic Alphabet (IPA). The second new vowel letter, ɥ, was used to represent or.

Franklin proposed the use of doubled letters to represent what he called long vowels, represented by modern phonemes in IPA thus: long versus short  (or, in his notation, Franklin’s letter ah as in A scheme for a new alphabet.svgFranklin’s letter ah as in A scheme for a new alphabet.svg versus ), long  versus short  (ee versus e), and long  for short  (ii versus i). In his examples of writing in the proposed alphabet, Franklin contrasts long and short uses of his letter e, with the words "mend" and "remain" which, respectively, he spelled mend and remeen. In this system, ee is used to represent the sound in "late" and "pale". Likewise, ii is used to represent the sound in "degrees", "pleased", and "serene". Sometimes Franklin's correspondences written in the new alphabet represent a long vowel not using a double letter but instead using a letter with a circumflex, ◌̂, as when he represents the sound in "great" and "compared" with ê instead of ee. Franklin's long-short vowel distinctions appear not perfectly identical to the same distinctions in 21st-century English; for example, the only word shown to use is the word all, but not other words that in modern notation would use. This discrepancy may reflect Franklin's own inconsistencies, but, even more likely, it reflects legitimate differences in the English phonology of his particular time and place.

Franklin does not make a distinction between the modern and  phonemes (in words like goose versus foot), which likely reveals another difference between 18th-century English pronunciation versus modern pronunciation.

Consonants
Franklin's proposed alphabet included nineteen letters to represent consonants. This set consisted of four new letters, in addition to fifteen letters from the existing English alphabet: b, d, f, g, h, k, l, m, n, p, r, s (including the long s, ʃ, typical of his era) t, v, z. New letters were proposed to replace the English digraphs ng (= ŋ); sh (= ); voiced th (= ), and voiceless th (= ). New consonant digraphs based on these new letters were used to represent the zh sound of measure (= z) and the affricate sounds of ch in cherry (= t) and j in jack (= d).

The most influential of Franklin's six new characters appears to have been the letter "eng",, for ng. It was later incorporated into the IPA. Alexander Gill the Elder used this letter in 1619.
