1. Google Voice Search
With Google Voice Search, you can quickly search your phone, the web, and nearby locations by speaking, instead of typing. Call your contacts, get directions, and control your phone with Voice Actions is possible, but is only available in US English for now.
Skyvi (Siri for Android)
Skyvi can do a lot for you: send and read texts, call contacts, find locations, get directions, play music, retrieve weather information, tells jokes, update social media with voice, and more. The only problem is getting those features to respond to voice accurately.
Speaktoit Assistant is a brilliant voice assistant for your Android device. It understands (almost) everything you say as voice commands and responds to it accordingly, and the app is named among Top 10 Android apps of the Year by New York Times.
Vlingo is probably the best voice-control app for Android. Vlingo lets you send texts and emails, voice dial, find local restaurants and businesses, buy movie tickets, open apps, update Twitter or Facebook, and more, all with your voice. The app is my favorite and I spent most of the time on it.
iris can do the usual: calendar (Remind me of the meeting coming Friday), call and text contacts, Google search, weather reports, find locations, set alarms, and interact with social media. Iris’s speech recognition is impressive. No matter what I said, she heard me perfectly.Iris might be the original Siri alternative (look at their names!), but it has fallen behind a bit.
If you use another Siri-type app for Android, let me know in the comments!
