Speaktoit Assistant is conversant in English, Spanish, Portuguese, German and Russian -- and the app is free as of this writing. You choose your assistant's on-screen appearance; there are two male and two female characters available. Using your voice, Speaktoit Assistant lets you compose emails and text messages, insert calendar items, take notes, find news and traffic information, tweet, update Facebook, hunt down nearby restaurants, get reminders about scheduled events and more. You can also customize tasks; for example, you can program your iPhone to open your contacts list when you say "Peeps." Speaktoit Assistant requires iOS 4.3 or later, and the company says the app is optimized for iPhone 5.
