Phonology

There are two scripts for the SPEL core-language, one based on URL-compatible ASCII and one based on IPA. If you are unsure of how to pronounce a letter, then simply copy paste the IPA letter into wikipedia which will give ample explanation.

Notes

Alignment: the 'h' or /ʰ/ is a semi silent h /h/, and is used mostly for alignment purposes. All words when written in text are either 2 or 4 glyphs long. However some root and grammar words are three letters, thus they need alignment. For 3 letter roots of the form CVC (consonant vowel consonant) the h prefixes the word, turing it into hCVC, for 3 letter grammar words of the form CCV, the h is suffixes it, turning it into CCVh. A simple way to remeber this is that all words must comply with the CCVC or CV form. So if a three letter word is missing one of those C's then replace it with an 'h' to get proper alignment.
Glottal stops: glottal stop '.' is only used for foreign quotes, such as that of proper names, as they don't necessarily conform to alignment rules
Tones: Tones '7' and '_', are mostly availble for future expansion of the vocabulary, and haven't yet come into play.
Clicks: Clicks '1' or '8' are used for temporary words and variables, especially useful to make short forms of compound words which are often used in a text or flock of people. Other options for short-forms are acronyms which must comply with the phonotactic rules of the language and be grammatically marked as acronyms, and initialisms, which are foreign quotes as they don't fit the phonotactic rules.

Currently the phonology is pretty much finished, however if there are some compelling arguments then it may still be modified.
