Google just released a speech recognition app for Android phones called Voice Actions. Now you can control your Android phone by using your voice.
With this app, you can call your contacts, send texts messages and email, listen to music, browse through the web, and can perform all common tasks, just by speaking into your phone.
Voice Actions requires Android 2.2 (Froyo) or higher, and will be pre-installed with the new Droid 2 phone from Motorola and Verizon. (If you have another phone with Android 2.2 (like the Nexus One, HTC Evo or the original Droid), you’ll need to download and install the app).
Voice Actions are currently available for U.S. English speakers only. More information and download Voice Action available at source [via].
