The growing ability to access microphone data on devices like smartphones and tablets enables our technology partner to aggregate and analyze voice data during pre-purchase conversations.

Key word is “technology partner”. They’re buying voice transcripts ripped from someone else’s spyware and selling the service of scraping it for keywords and maybe somehow tying that back to an individual by cross-referencing the hit against data from traditional above-board ad platforms.
