Everybody talks about (and often to) the Big Four virtual assistants — Siri, Alexa, Cortana and Google Assistant. But many other companies are working on virtual assistants, too.
Huawei is working on a virtual assistant for the Chinese market.
Samsung offers Bixby on its Galaxy S8 or S8+ smartphones.
Voice recognition giant Nuance offers an enterprise ready virtual assistant called Nina, which specializes in knowing the limits of A.I. and kicking queries over to a team of human assistants when necessary. Nuance this month announced a Nina "skill" on Amazon's Alexa platform.
