Although SayHi is not the first IOS app to do the same function since Vocre, another iPhone app can do the same and is offered for free, it is a little difficult to use and not effective enough to understand voice command.
SayHi comes in a simple interface for starters and easily translate the language to your liking by simply pushing the screen button, speak and push it again to get the translated language. The app is using the internet to translate the language you have spoken and then it returns the result by speaking the text in the language you want it to be translated. Thus, you need a steady internet connection to use the app.
This app is available for download at ITunes for $2.99.
