Google introduced an improved Google Translate for Android Conversation Mode:
"This is a new interface within Google Translate that’s optimized to allow you to communicate fluidly with a nearby person in another language. You may have seen an early demo a few months ago, and today you can try it yourself on your Android device.
"Currently, you can only use Conversation Mode when translating between English and Spanish. In conversation mode, simply press the microphone for your language and start speaking. Google Translate will translate your speech and read the translation out loud. Your conversation partner can then respond in their language, and you’ll hear the translation spoken back to you. Because this technology is still in alpha, factors like regional accents, background noise or rapid speech may make it difficult to understand what you’re saying. Even with these caveats, we’re excited about the future promise of this technology to be able to help people connect across languages" (http://googleblog.blogspot.com/2011/01/new-look-for-google-translate-for.html?utm_source=feedburner&utm_medium=email&utm_campaign=Feed:+blogspot/MKuf+(Official+Google+Blog), accessed 01-14-2011.
