The White Flag AA meeting (p. 365)
It is the first time he realizes that Joelle’s voice—crisp and rich and oddly empty, her accent just barely Southern and with a strange and it turns out Kentuckian lapse in the pronunciation of all apicals except s—is familiar in a faraway way that both makes it familiar and yet lets Gately be sure he’s never once met her before, Out There.
Context
The narration introduces Joelle's voice in working phonetics — "apicals" is a linguist's term, conspicuously not Gately's — right at the moment the voice is about to reveal a grammarian's mind behind the veil. It's also the Madame Psychosis recognition Gately keeps missing: the voice is characterized with radio-professional precision because it is, unbeknownst to him, a radio professional's.
