If you haven’t already installed the Chrome extension for voice search, then do it!
This is the future of search and the reason Hummingbird will change the way we optimise sites for search. The results are no longer directly coupled to individual keywords, but rather to the sequence of the queries. Google connects the identifiable entities and makes sense of the relationships between queries in order to determine the most relevant sites to return in the mix.
The linking of a sequence of queries is makes it possible to determine the intent of a search query without the need for ‘caveman’ terms. Natural conversation is all that is required.

Google is able to provide the information sought without the visitor visiting any other site in this search journey…
