Tillamook is an extinct Salishan language, formerly spoken by the Tillamook people in northwestern Oregon, United States. The last fluent speaker is believed to have died in the 1970s; between 1965 and 1972, in an effort to prevent the language from being lost, a group of researchers from the University of Hawaii interviewed the few remaining Tillamook-speakers and created a 120-page dictionary.
The "rounded" consonants (marked by ʷ), including /w/, are not labialized—the effect is created entirely inside the mouth by cupping the tongue. Uvulars with this distinctive internal rounding have "a kind of ɔ timbre" while "rounded" front velars have ɯ coloring. These contrast and oppose otherwise very similar segments having ɛ or ɪ coloring—the "unrounded" consonants.
/w/ is also formed with this internal rounding instead of true labialization, making it akin to /ɰ/. So are vowel sounds formerly written as /o/ or /u/, which are best characterized as the diphthong /əw/ with increasing rounding.
