As mentioned above, we have attempted to reformulate allophonic rules in terms of rewrite rules. How can we reformulate these rules as phrase-structure rules? Basically, we will introduce additional constituent categories to encode contextual conditions. For example, one might want to say that a /t/ obligatorily aspirates before a vowel as in a word like Tom.
