I'm not up on all the technical terms, so I'll "cheat" with wikipedia. They have [k] for <g> and [t] for <d>. Therefore my ealier IPA transcription was wrong: /kí.tí/
And I was talking about the way consonants are partially devoiced, such as in Mohawk (that one I know has that phenomenon via earlier discussions with Formiko). Which is usually affected by the surrounding sounds.
A general browsing of the page for Navajo says nothing about that, but then again neither does the Mohawk page, so . . . .
Thanks for asking me to clarify Linguoboy. I learned a thing or two.
