Currently missing:
* Function for final obstruent devoicing of d, g, b, s, r (ɐ̯)
* Function for pre-consonantal obstruent devoicing of d, g, b, s
* Function to reduce geminates
* List of environments which trigger the palatalisation of /x/ (liquids + non-low front vowels)
* Function to determine if H is word initial (> /h/) or non-initial (> 0) (⟨-ehe⟩- should be /eː/ in verbs only)
* Function to put stress in general, function to check for prefixes and realign stress accordingly.
* Function to convert ⟨e⟩ in unstressed syllables to ə > Function to reduce -ər to -r + "devoicing"
* Function to convert ⟨c⟩ before front vowels to /t͡s/?
* An input whether the word is Germanic or Romanic might make a lot of exceptions
predictable/automatable, e.g. /ɪ, ɔ, ʊ/ > /i, o, u/ for short vowels in closed syllables,
penultimate or final stress
* The unseparable prefixes do not take stress > Stress on the 2nd syllable
** A complete list could be compiled and the process automated, instead of making the user enter the stress by hand
* Rules to determine when to make vowels short vs. long. There will need to be
ways to override this; I think they should be adding an h to force length,
and either using a breve (e.g. ă ĕ ĭ) or maybe doubling the following consonant
to force shortness. What should those rules be? Some guesses:
- vowels should be short before a geminate consonant
- vowels should be long in a stressed open syllable
- vowels should probably be long in a stressed final syllable before a single
consonant (but with possible exceptions, e.g. '-eg')
- vowels should probably be short before two consonants (except possibly 'st'?)
- syllables with secondary stress should be treated as if stressed
- syllables directly following a known prefix (aus-, zu-, über-, ge-, etc.)
should be treated as if stressed, whether they are actually stressed or not
- when there's an explicit slash to separate compounds, all parts should be
treated as if they were separate words for vowel-length purposes (e.g.
'-tag' in 'Reichs/tag' should be long)
- what about other unstressed syllables?
