If you use voice assistants to make calls and look up businesses you may be open to a new scam targeted at people who use voice assistants to find services and companies. 

When you say "hey Google, call Bobs Plumbing" you would expect to get Bob or his staff to answer the phone when you have called but you may get another business or a scammer who has pushed thier listing in front of Bob's. The best protection is to use voice to research the business you need to contact and look for their website to make sure they are real.
