If you’ve jailbroken your iPad to run 3rd party applications then the first thing you can try a small hack to enable “Voice Control” feature like iPhone 3GS. Note of a caution, jailbreaking and installing 3rd party apps can destabilize your iPad, reduce its battery life and most importantly Apple discourages jailbreaking. If you’re ready, you can follow the steps below to enable voice control.

1. Use WinSCP for Windows and for Cyberduck for Mac users.
2. Install OpenSSH on your iPad using Cydia. You’ll have to restart your iPad after that.
3. Next use the following settings to log into your iPad:
   IP address of your iPad
   user name: root
   password: alpine
   protocol: SCP (SFTP for Cyberduck)
4. Navigate to /System/Library/CoreServices/SpringBoard.app
5. Open K48AP.plist in a text editor or a plist editor
6. Under the capabilities area add the following key

<key>voice-control</key>

<true/>

7. Save and Reboot your iPad. Voila, Voice Control should work!
