The Symbolic Phonetic Notation (SPN) is a set of phonetic notation symbols developed by Kalmasoft with the sole purpose of preserving unwritten languages by reproducing their sound in a manageable way; preserving the phonological aspects of any targeted language can be made easy by electronically processing its intermediate representation using SPN which fits easily for such purposes, it can also be managed programmatically or by any other well defined analytical means.

SPN symbols were carefully designed to represent the anatomy of speech organs while articulating various sounds as precise and intuitive as possible, the notation system is composed of symbols that are easy to memorize and write though not as comprehensive and versatile compared to the current complex IPA symbols for example; SPN symbols simply depict the positions of the tongue and lips and the other articulatory organs as they produce the sound, hence it is a phonetic notation.

SPN is not meant to serve as a writing system and should not be dealt with as such, it is rather a "utility set of symbols" that doesn’t stand by itself for any specific language and should not be considered as a "writing system" in any sense; a separately designed writing system is highly recommended in order to have a complete linguistic solution for any arbitrary targeted language.

All SPN symbols are temporarily assigned in the range EC00-EFFF of the Unicode Private Use Area, so the only way to access or view the symbols is by using the font from within the desktop applications e.g. text editors/word processors or by any other suitable programming solution.

The table shown below contains non-standard Unicode characters in the column "Font". Without proper rendering support, you may see question marks, boxes, or other symbols instead of the correct intended characters, this web page uses SPN truetype font which may or may not work properly on your browser, an image copy of the same symbols are included in the column "Symbol" for reference just in case the characters do not appear correctly. You may download the SPN font from our download page lingual support page for your testing purposes.

Quantities are represented using special symbols depicting numbers, these are added for consistency purpuses; SPN numbers are self-explanatory, each symbol depicts the count of angles, symbols with closed shapes (triangles) are the higher values of the decimal system.
