iDownloadBlog reports on a new package available for jailbroken iPhones that enables Siri-like dictation on previous generation iPhones. The package is called Siri0us and is being distributed via Cydia to jailbroken devices only.
Dictation works great on the iPhone 4, transcribing words into text rather quickly. The technology is actually Naunce-based dictation, but the end result is pretty much the same as Apple’s Siri. As you can see in the video, small ads are displayed in the bar above the mic icon. You will need an internet connection for the microphone to show up.
The package seems to emulate the Siri interface for dictation, but reportedly uses Nuance speech recognition on the backend. This video shows it in action:
There have been a number of attempts to port the entirety of Siri to previous generation devices, but those attempts have been limited by the need for Apple server authentication. This port bypasses Apple's servers and seems to use Nuance for the voice recognition engine. Of course, you won't get Siri's artificial intelligence features or sassy attitude, but you can get some on-the-go dictation.
