Congress Spelling System
The Congress Spelling System (Malay: Ejaan Kongres) is a spelling reform of Malay Rumi Script introduced during the third Malay Congress held in Johor Bahru and Singapore in 1956. The main characteristics of the system are the use of symbols in the Americanist phonetic notation, going by the dictum of one symbol for one phoneme, and the new proposition in the writing of diphthongs.
