"For the first time, we were bringing the capabilities supported onGoogle Translate—like machine translation, romanization of non-Roman scripts and spoken translations—to the Android platform. We also offered voice input to let you speak the word or phrase you wanted to translate instead of typing it in, and SMS translation so you could translate SMS messages sent to you in foreign languages."
