I often use voice search for Google on my android phone. The quality of Google voice search is very good. Its accuracy level is amazing! When you open google.com on your computer, you can see voice search option at the right corner of the search box. But when I opened bing.com, I never found any option for voice search there. Is there voice search for Bing search engine? I do not have windows phone, but I hope they would at least have voice search for their windows phones.
