QUESTION: Clarification on training a new model with phone groups and phonological rules

[stefanocoretta]

Hi! Sorry if I am posting here, but I wasn't sure whom to write to.

I am planning to train an acoustic model for Albanian but I am not entirely sure how the phone groups and phonological rules work.

To give an example, in word final position <ë> is variable produced as [ə, ɜ, ʌ] or zero. How would I go about that?

Also, NC clusters in word initial position are phonetically homorganic. Does this mean the dictionary would have for example n ɡ ɻ a but I would write a phonological rule to change n to ŋ before velars?
