I have noticed that the only contact that I can use voice command dialing is the one I manually entered. The rest of my contacts were synced from Exchange. If I try to voice dial them it just brings up a google search for ex. "Call Beth Price Mobile". One of the search results will be "Beth Price" with add a number below it, even though she is in my contacts already. So I go to contacts and edit her entry. She is listed as a Corporate Contact. I believe that voice dial is not working with corporate contacts. The only one working is listed as a google contact. This is the one I manually entered earlier. I am not syncing my google contacts. Anyone else experience this or know a work around?
