VoiceSearch allows you to perform voice searches through Google from any iOS application

  VoiceSearch is a tweak released today in Cydia that implements in our iDevices the option to perform voice searches through Google, no matter where we are in iOS. The tweak works with the help of the Activator plugin, and through it you will run the command that activates it and gives you the possibility to perform the search. The most interesting part of this tweak is not in the fact that you can perform voice searches through Google, but in the fact that you can open the search interface over any iOS application, thus simplifying the process.

Search Google from anywhere using your voice! Configure with Activator. Looking for a full Siri alternative? Try Esra Assistant on Cydia! Configure from Settings > Activator.

  The tweak is available for free in Cydia, but from the Activator settings menu you can choose the action by which you can activate the interface.
