The ability to segment letterstrings (=words) in manageable particles is an important requirement for the successful learning process of spelling and reading. Segmenti supports the segmenting of words in syllables or morphemes with educational games. It contains ten game modules and a reading module. In "Count Syllables" there are four levels to count the syllables. Optionally the word can be typed afterwards. In "Separate into Syllables" a random text from "Grimms Mrchen" is selected for a game and each sentence has to be separated into syllables. In "WordSearch" words with selected roots are hidden in a grid filled with random letters. They have to be highlighted with the cursor. In "Highlight the Root" the awareness is focussed on the most important segment of a word by underlining the root. In "Short or Long Root Vowel?" the root vowel has to be selected and the length has to be defined, also in "Root Vowel in Text". In "Build Words" words have to be build from most frequent segments. In "Rebuild Words" words must be rebuild by morphemes. In "Jumble" the letters of the root and in "Morphem-Mix" the morphemes are scrambled. In "Guess the root" an appropriate root has to be found and in "Capital or Small" the case of the first letter must be defined. There are other game options: "Memorize", "Halffont", "Guess Root Vowel", "Show Consonants", "Dictation", etc. In "Morpho" words have to be constructed from random morphemes. In "Insert Roots" the missing roots must be written. The results of every game session can be recorded and analyzed by the special protocol module. This complex set of programs practises the awareness of word segments in an innovative way. The segmenting ability is the key for a successful word processing.
