Interskript

From annawiki

Overview

Interskript includes a bijective mapping of 26 internationally most common letters to 26 common phones which in IPA are represented by a single character.

The mapping allows for a

  1. common pronunciation of internationally established written forms of scientific names for
    1. chemical elements (e.g. Yttrium)
    2. taxons (e.g. Moschidae)
  2. common spelling of internationally established broadly similar pronunciations of names for
    1. persons (e.g. Pjotr Iljitc Tcaikovski, Dqengis Kan)
    2. places (e.g. Tcomolungma, Tcile, Canghai).

Character-phoneme mapping

An uppercase character represents the same phoneme as the corresponding lowercase character.

To have a bijective mapping only one set - uppercase or lowercase - has to be used.

Short notation

Since Interskript in regular form does not use diacritic signs the latter can be used to record vowels above consonants.
