How has voice input evolved in local search? It is slowly becoming more popular in web search, but IMO voice seems especially suited for local results, particularly when done from mobile.
I use my mobile phone for GPS driving, mounted on the dash of my car, and will often ask Google for nearby resources & driving instructions.
A large part of the requests I make to my Google Home (in my workplace) is for nearby businesses. Since my phone is Android, I can then sent location & other info to my phone. This process works really well.
