Google have updated the iOS version of the Chrome browser. The latest version of the browser for the iPad and iPhon has new improved voice search that Google say is faster than the old version and it then will read the results back to you. I found that some results it would read to you and some just did a regular Google search depending on whether Google has an info card for the results. There are also speed improvements and the usual security and bug files.
The app is free from the iTunes store.
