Siri
Siri is a voice assistant feature found in the iPad 3, iPad mini 1G, iPhone 4S, iPod touch 5G, and their successors. Although it has been present since iOS 5 (with the iPhone 4S), Siri is still not perfect and therefore still considered to be in beta. A port to older devices has been completed by stroughtonsmith with the help of chpwn, and is available in Cydia as Spire.
Files
Siri is an integral part of iOS 5 for the iPhone 4S and any supported iDevices. Files and folders include:
- /Applications/Preferences.app/*.lproj/*Assistant.strings
- /Applications/Preferences.app/*Assistant.plist
- /System/Library/AccessibilityBundles/AssistantUI.axbundle/ (iOS 5 and 6)
- /System/Library/AccessibilityBundles/AXExtraExtras.axbundle/ (iOS 5 and 6)
- /System/Library/AccessibilityBundles/*-Assistant.axbundle/
- /System/Library/Assistant/
- /System/Library/CoreServices/SpringBoard.app/Assistant* (iOS 5)
- /System/Library/DataClassMigrators/Siri.migrator/ (iOS 6 and 7)
- /System/Library/LaunchDaemons/com.apple.assistant*.plist
- /System/Library/PrivateFrameworks/AssistantServices.framework/
- /System/Library/PrivateFrameworks/AssistantUI.framework/
- /System/Library/PrivateFrameworks/Preferences.framework/*.lproj/AssistantShared.strings (iOS 5 and 6)
- /System/Library/PrivateFrameworks/SAObjects.framework/
- /System/Library/PrivateFrameworks/SiriUI.framework/ (iOS 7)
- /System/Library/PreferenceBundles/Assistant.bundle/
- /System/Library/SpringBoardPlugins/Assistant.uibundle/ (iOS 6 and 7)
- /System/Library/UserEventPlugins/AssistantUEA.plugin/
Although other iOS 5 devices are capable of running Siri, they do not include the above files that are required for it to work.
In iOS 5 and 6, an additional key in the capabilities section of /System/Library/CoreServices/SpringBoard.app/XXXAP.plist must be added for the device to enable Siri:
<key>assistant</key> <true/>
In iOS 6 (and above), Siri is supported by the 3rd generation iPad, 4th generation iPad, iPad Air, iPad mini 1G, iPad mini 2G, iPhone 4S, iPhone 5, iPhone 5c, iPhone 5s and iPod touch 5G. For iOS 6 and 7, Apple included the Siri bundle that moves both Siri's UI and Mic artwork from /System/Library/CoreServices/SpringBoard.app/ to:
- /System/Library/SpringBoardPlugins/Assistant.uibundle/
Also new migrator bundle for Siri:
- /System/Library/DataClassMigrators/Siri.migrator/
Another key related to Siri, "Raise to Speak" capability, for iPhone with iOS 6 only (in DeviceTree for iOS 7):
<key>siri-gesture</key> <true/>
Installation
The installation of Siri on other devices requires access to the iPhone 4S filesystem, to copy over the files above to a jailbroken device running iOS 5. Then assistant is enabled in the capabilities plist as above, and the device is rebooted.
Holding down the home button for a second should activate the Siri tray at the bottom of the screen, but saying anything will make it say it can't connect. This is due to the device requiring an identifier that the Siri servers generate every 24 hours for 4Ses. SiriProxy can overcome this if you have access to a 4S.
The stock assistant images from the 4S are only available in Retina size. On non-Retina devices (iPad and iPhone 3GS), this means many interface features may look different. The theme Siri Graphics for iPhone 3GS and iPad in Cydia fixes this.
Changing Server
The server that Siri sends its data through can be changed in a number of ways. The most reliable method is to use a DNS server, as demonstrated by plamoni.
An easier approach is to edit the com.apple.assistant.plist file in the device's /var/mobile/Library/Preferences folder. It can be changed either on a jailbroken device with iFile, or via an iPhone backup reading utility. The hostname string simply needs to be replaced with the URL of your SiriProxy (i.e. your computer's IP address). This method could also allow for your SiriProxy to work outside of your Wi-Fi network, if you set up forwarding for port 443 to your computer in your router, and use your external IP address. However, some routers don't do port forwarding inside of their network, so you would need to change this setting yourself when you arrive or leave home. A static IP or dynamic DNS address (such as one from Dyn) is recommended.
The /etc/hosts file on a jailbroken device can also be modified. This can also be used externally, like the above method, though domain redirects are disallowed in host files, so a static IP is required. For instance, if you have a server which has the IP 192.168.1.5, enter this on a new line:
192.168.1.5 guzzoni.apple.com
Make sure there is at least one blank line at the very end of the file, or this will fail.
