Voice Browser - Speak & Search is an Android browser that lets you search the web using your voice. It can recognize speech and translate it to text, so you can search for whatever you want without typing. Just tap on the microphone to start talking; the app will listen and find what you’re talking about. 

Once you’re finished talking, it will show you the results, and you can even play the speech to make sure you understood what you said. You can also save the results for later. This voice browser is free and can be used on your Android device.
