As with the Android version, the app taps into Google's Knowledge Graph function to consider the user's location and the context of what is being searched.
This means that the app can suggest films at nearby cinemas when users ask "What movies are playing this weekend?" or understand that a search for 'Rio' could mean a city, movie or casino.
Comparisons with Apple's Siri are bound to be made -- not least because both apps can respond to direct questions -- but in reality Google Voice Search is someway off its Apple rival. After all, Siri is able to search and carry out other functions across the Internet, apps, calendar entries and messages.
The free Google Voice Search app is currently available for Android on the Google Play store but will come to Apple's App Store in the coming weeks.
