Unifon

Unifon is a defunct Latin-based phonemic orthography for American English designed in the mid-1950s by John R. Malone, a Chicago economist and newspaper equipment consultant.

It was developed into a teaching aid to help children acquire reading and writing skills. Like the pronunciation key in a dictionary, Unifon attempts to match each of the sounds of spoken English with a single symbol, though not all sounds are distinguished, for example, reduced vowels in other American dialects that do not occur in Chicago. The method was tested in Chicago, Indianapolis and elsewhere during the 1960s and 1970s, but no statistical analysis of the outcome was ever published in an academic journal. Interest by educators has been limited, and its last formal use (for the Tolowa language) was abandoned in 1996, but enthusiasts continued to publicize the scheme and advocate for its adoption as late as 2012.

The Unifon alphabet contains 40 glyphs, intended to represent the 40 "most important sounds" of the English language. Although the set of sounds has remained the same, several of the symbols were changed over the years, making modern Unifon somewhat different from Old Unifon.

Of the 66 letters used in the various Unifon alphabets, 43 of the capitals can be unified with existing Unicode characters. Small letters are printed as small capitals. Fewer of them are available in Unicode as dedicated small-cap forms, but the usual Latin minuscules can be made small-cap in a Unifon font. Unifon is the same as English but with extra letters. Letters have corresponding IPA phonemes below them.

Other letters include:

Some fonts may have Unifon symbols in Private Use Areas.

Under a contract with the Bendix Corporation, Malone created the alphabet as part of a larger project. When the International Air Transport Association selected English as the language of international airline communications in 1957, the market that Bendix had foreseen for Unifon ceased to exist, and his contract was terminated. According to Malone, Unifon surfaced again when his son, then in kindergarten, complained that he could still not read. Malone recovered the alphabet to teach his son.

Beginning before 1960 and continuing into the 1980s, Margaret S. Ratz used Unifon to teach first-graders at Principia College in Elsah, Illinois. By the summer of 1960, the ABC-TV affiliate station in Chicago produced a 90-minute program in which Ratz taught three children how to read, in "17 hours with cookies and milk," as Malone described it. In a presentation to parents and teachers, Ratz said, "Some have called Unifon 'training wheels for reading', and that's what it really is. Unifon will be used for a few weeks, or perhaps a few months, but during this time your child will discover there is a great similarity between Unifon and what he sees on TV screens, in comics or road signs, and on cereal boxes. Soon he finds with amusement that he can read the 'old people's alphabet' as easily as he can read and write in Unifon."
