Google translate is one of the most useful apps out there and now it will allow you to translate text without even having to switch between the app you are currently in and Google Translate. In supported messaging applications like Whatsapp, all you will need to do is copy the text that you want to translate and an option to use Google Translate will become available on the spot. You will however, need to be running at least Android version 4.2 (the later the better) to avail the feature though.
Apple users on the other hand, will get access to the offline translation feature on Google Translate for the first time. One may say that it's a little late though as the ability to translate without an active internet connection has been a part of the Android OS versions for quite a while now. Nevertheless, Google has improved upon the feature by compressing the 52 downloadable language packs to roughly 25MB each. The summary is that both iOS users and Android users of the Google Translate will be getting updates, albeit with varying added functionalities.

According to a new rumor, Google is working on a Revolutionary new Real-time Voice Translation System. This new App will allow users to speak in their native language (e.g. English) and the receiver will get real-time translation in his own language (e.g. French). A report by New York Times claims that the new functionality will be released as an update to Google's Mobile Translate app on Android.
There are not a lot of details right now, but one thing is clear. Google won't be offering two-way real-time voice translation. Instead, it will pick up any ongoing dictation in a popular language with your phone's microphone and automatically translate it to a language of your choice using the already present capabilities of the Google Translate app. Currently, it offers written translation from/to 80 languages.
According to NYT, Google will also announce a service that will let you point your phone to any foreign street sign and get an automatic translation.
