  • Patent number: 4696492
    Abstract: A phonetic alphabet in script form called soundwriting was first adapted to English with thirty-seven letters, each representing a separate speech sound. The script uses no silient letters or other learning blocks. Spelling is made regular using soundwriting. It is adapted to a keyboard.By adding additional letters to represent new sounds the script has been expanded to include sounds of French, Spanish, Italian and German with only forty-six symbols. The spelling of these languages in soundwriting is also completely phonetic which eliminates spelling difficulties in these languages. New letters to expand soundwriting are on the keyboard. A temporary letter is used when adapting a new language to soundwriting until a permanent letter is designed for it and placed on the keyboard. Soundwriting provides a simpler and easier way of learning the vocabularies of languages to which it is adapted.
