System for coding alphabet pronunciation

摘要

A system for coding letters in an alphabet for word pronunciation is disclosed. The system includes a first code indicator (12) for association with letters for indicating a lower case letter sound; a second code indicator (14) for association with letters for indicating an upper case letter sound; a third code indicator (16) for association with letters for indicating a silent letter sound; and a fourth code indicator (18) for association with letters for indicating use of a sound varied from the upper or lower case sound, and having a variation sign for indicating that the associated letter or letters are for a sound varied from the lower case or upper case letter sound of the associated letter or letters, and a variation symbol for indicating a predetermined variation sound for the associated letter or letters. The first and second code indicator may be associated with two or more letters for indicating blending of the sounds of the associated letters. The system may be incorporated in a computer program and may include sound generating means arranged to generate an appropriate sound signal for the or each of the associated code indicator and words.
