Nokia Lumia 510 - How can I control Bing search through speech commands on my Lumia phone?

With Bing search, you can use either the virtual keyboard or your voice to enter your search commands. 

To search the web with your voice,

  1. Press Search key at the bottom of the screen.
  2. Then press a Voice button shaped like a microphone (the Bing search page varies of your Windows Phone version, region + language settings).
  3. Once pressed, the phone will display listening, then say your search term.
  4. If a voice recognition is successful, proposed matches appear on the screen. 

Note: Certain features of Bing, such as Search with speech and local Search results, may not be available in your country or region. Refer to the Feature and Service Availability at www.windowsphone.com.
