Following up on my research:
I had trouble on the Canadian site (closest I could come was ) https://www.firstvoices.com/explore/FV/sections/Data/Coast%20Salish/Halkomelem/Stz%E2%80%99uminus
So I kept looking.
The Puget Sound Salish tribes including the Puyallup, Snohomish, Muckleshoot, Snoqualmie, Nisqually, Skagit, Suquamish, Squaxin, Swinomish, Stillaguamish, and Sauk-Suiattle tribes.
So resources for language/pronunciation for these tribes would be Lushootseed - http://www.native-languages.org/lushootseed.htm
Next I need to figure out which Tribes for the specific location of my meeting, or use a wider net. Since it is a state-wide meeting, should I consider the Tribes from other areas if we think of the state, or just focus on the geographic location?
