What counts as Voice AI

A company joins this map when its own site describes Voice AI as its main product and an independent source confirms it. Out of scope: contact-center suites where voice AI is a feature, voice features inside large platforms, and telephony carriers. Definitions are versioned; this is version 1. Corrections need a public source: see Contact.
