'''Siri''' is a voice assistant feature of the [[N94ap|iPhone 4S]] and one of the main selling points for this device, although still in beta. A port to iPhone 4 and late model iPod touch has been completed by {{twitter|stroughtonsmith}} with the help of [[User:Chpwn|chpwn]], and is available in Cydia as [cydia://package/com.chpwn.spire Spire].

Siri is an integral part of iOS 5 for the iPhone4S. Files include:
  
−
* /System/Library/PrivateFrameworks/AssistantServices.framework
  
−
* /System/Library/PrivateFrameworks/AssistantUI.framework
  
−
* /System/Library/Assistant

== Porting ==
  +
  +
=== Additional Capabilities ===
  +
  +
In iOS 5 and 6, additional keys in the capabilities section of [[Model definition file|/System/Library/CoreServices/SpringBoard.app/XXXAP.plist]] would be added to enable Siri:
 
<key>assistant</key>
  
<key>assistant</key>
  +
<true/>
  +
<key>siri-gesture</key> // Raise to speak, activate Siri when you raise your phone to ear (iOS 6)
 
<true/>
  
<true/>
   
  +
Since the [[Model definition file]] is move along in iOS 7, in a DeviceTree instead. MobileSubstrate Hooking is required in order to inject these capabilities. (MGGetBoolAnswer(CFSTR("assistant")) for example)
−
== 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.
 
   
  +
=== Additional Filesystems ===
−
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 installation of Siri (its filesystems) on other devices requires access to the iPhone 4S or supported devices filesystem, to copy over the files above to a jailbroken device running the same iOS version, with correct files permissions.
−
The stock assistant images from the 4S are only available in Retina size. On non-Retina devices ([[iPad]] and [[N88ap|iPhone 3GS]]), this means many interface features may look different. The theme [cydia://package/net.sourceforge.adamscode.siri1xgfx Siri Graphics for iPhone 3GS and iPad] in Cydia fixes this.
 
   
  +
For iOS 5, the stock assistant images from the iPhone 4S are only available in Retina size. On non-Retina devices ([[K48AP|iPad]], [[iPad 2]] and [[N88AP|iPhone 3GS]]), interface features may look different and the theme [cydia://package/net.sourceforge.adamscode.siri1xgfx Siri Graphics for iPhone 3GS and iPad] in Cydia needs to be installed.
−
== 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 [http://www.youtube.com/watch?v=a9gO4L0U59s demonstrated by plamoni].
 
   
  +
Installing on iPad models running iOS 5 causes buggy interface, because the system usually forces the assistant window as full-screen. In this case, you have to manually edit the images to fix. Differently on iOS 6, assistant images are available both in Retina and non-Retina devices (for [[iPad mini]]), so you could copy the non-Retina images or artwork file from the non-Retina jailbroken devices.
−
An easier approach is to edit the <tt>com.apple.assistant.plist</tt> file in the device's <tt>/var/mobile/Library/Preferences</tt> 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 [http://whatismyip.com 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 [http://dyn.com Dyn]) is recommended.
 
  +
=== Shared Cache Injection ===
  +
  +
One last thing you have to do is [http://iphonedevwiki.net/index.php/Dyld_shared_cache dyld_shared_cache] injection, according to [https://twitter.com/stroughtonsmith stroughtonsmith] 's [https://twitter.com/stroughtonsmith/statuses/125168975377203200 tweet]. Because some of Siri binaries are there, without them mean Siri won't work.
  +
  +
*Copying <code>/System/Library/Caches/com.apple.dyld/dyld_shared_cache_armv7</code> from Siri-capable devices.
  +
  +
*Placing it in some directory in your target devices, take note for the location.
  +
  +
*Editing <code>/System/Library/LaunchDaemons/com.apple.SpringBoard.plist</code> using some good text editor, by adding these section:
  +
  +
<key>EnvironmentVariables</key>
  +
<dict>
  +
<key>DYLD_SHARED_REGION</key>
  +
<string>private</string>
  +
<key>DYLD_SHARED_CACHE_DIR</key>
  +
<string>THE FULL LOCATION OF YOUR DYLD SHARED CACHE HERE (FOR EXAMPLE: /var/mobile/folder_with_dyld_shared_cache_inside)</string>
  +
<key>DYLD_SHARED_CACHE_DONT_VALIDATE</key>
  +
<string>1</string>
  +
</dict>
  +
For iOS 6 and 7, both com.apple.backboardd '''and''' com.apple.assistant_service deamons must be injected the code too.
  +
  +
*The cache we inject is commonly from [[S5L8940|Apple A5]] devices, so the system won't be able to find the compatible graphics driver binary for [[S5L8930|Apple A4]] devices and causes massive slowdown and animation lag if the target devices aren't iPad 2 or iPad (3rd generation) (A5 devices) as they use the same driver. You can find the A4 Graphics driver named "IMGSGX535GLDriver" from Xcode-inside location: <code>/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS[THE iOS VERSION NUMBER].sdk/System/Library/Extensions/IMGSGX535GLDriver.bundle/IMGSGX535GLDriver</code> and place into your target devices at <code>/System/Library/Extensions/IMGSGX535GLDriver.bundle</code> directory. This method seems to be impossible for iOS 7 however, as the SDK no longer included the graphic binary.
  +
  +
*Save it and reboot the devices to take effect. Wrong cache location causes infinite SpringBoard crashing.
  +
  +
'''Purpose for iOS 5 devices'''
  +
*Add missing binary at /System/Library/Assistant/UIPlugins/SpringBoard.assistantUIBundle/SpringBoard
  +
  +
'''Purpose for iOS 6 devices'''
  +
*Add missing framework binary at /System/Library/PrivateFrameworks/AssistantUI.framework/AssistantUI
  +
  +
'''Purpose for iOS 7 devices'''
  +
*Add missing framework binary at /System/Library/PrivateFrameworks/AssistantUI.framework/AssistantUI (Applied to SiriViewService.app and SpringBoard)
  +
  +
== Connecting to Server ==
  +
  +
Holding down the home button for a second should activate the Siri tray at the bottom of the screen (iPhone, iPod and iPad running iOS 5), or at the area close to home button on screen (iPad running iOS 6+), but saying anything will make it say it can't connect because the server rejects any query from these unsupported devices. This is due to the device requiring an identifier that the Siri servers generate every 24 hours for Siri-capable iDevices.
  +
  +
=== Changing Server ===
  +
  +
[[SiriProxy]] can overcome the server connection issue if you have access to Siri capable iDevices. 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 [https://www.youtube.com/watch?v=a9gO4L0U59s demonstrated by plamoni].
  +
  +
An easier approach is to edit the <tt>com.apple.assistant.plist</tt> file in the device's <tt>/var/mobile/Library/Preferences</tt> 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).

A static IP or dynamic DNS address (such as one from [http://dyn.com Dyn]) is recommended.
   
 
The <tt>/etc/hosts</tt> 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:

=== Bypassing Authentication ===
  +
  +
Alternative to dealing with SiriProxy, it's also possible to trick the Apple server that you are using a Siri-capable device by simply faking device model that the system would include as a "header" to send to the Apple server (method <code>-[ADAceConnection _startConnection]</code> does that). It could be achieved this way: [https://github.com/PoomSmart/SiriAuthFix/blob/master/Tweak.xm SiriAuthFix].

Siri is a voice assistant feature found in the iPad (3rd generation), iPad mini, iPhone 4S, iPod touch (5th generation) and their successors. Siri has been present since iOS 5 on the iPhone 4S.

A legal port to older devices has been completed by @stroughtonsmith with the help of chpwn, and is available in Cydia as Spire. Spire is only compatible with iOS 5.0.1. There are other ports which are compatible with more iOS versions (iOS 5.1.1 through 7.x), but not all of them are reliable. Ports are not needed as of iOS 8 though as all compatible devices support Siri.

From iOS 6, Siri is supported by iPad (3rd generation) and newer, iPhone 4S and newer, iPod touch (5th generation) and newer, and with all generations of iPad mini.

One last thing you have to do is dyld_shared_cache injection, according to stroughtonsmith 's tweet. Because some of Siri binaries are there, without them mean Siri won't work.

  • Copying /System/Library/Caches/com.apple.dyld/dyld_shared_cache_armv7 from Siri-capable devices.
  • Placing it in some directory in your target devices, take note for the location.
  • Editing /System/Library/LaunchDaemons/com.apple.SpringBoard.plist using some good text editor, by adding these section:
<key>EnvironmentVariables</key>
<dict>
    <key>DYLD_SHARED_REGION</key>
    <string>private</string>
    <key>DYLD_SHARED_CACHE_DIR</key>
    <string>THE FULL LOCATION OF YOUR DYLD SHARED CACHE HERE (FOR EXAMPLE: /var/mobile/folder_with_dyld_shared_cache_inside)</string>
    <key>DYLD_SHARED_CACHE_DONT_VALIDATE</key>
    <string>1</string>
</dict>

For iOS 6 and 7, both com.apple.backboardd and com.apple.assistant_service deamons must be injected the code too.

  • The cache we inject is commonly from Apple A5 devices, so the system won't be able to find the compatible graphics driver binary for Apple A4 devices and causes massive slowdown and animation lag if the target devices aren't iPad 2 or iPad (3rd generation) (A5 devices) as they use the same driver. You can find the A4 Graphics driver named "IMGSGX535GLDriver" from Xcode-inside location: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS[THE iOS VERSION NUMBER].sdk/System/Library/Extensions/IMGSGX535GLDriver.bundle/IMGSGX535GLDriver and place into your target devices at /System/Library/Extensions/IMGSGX535GLDriver.bundle directory. This method seems to be impossible for iOS 7 however, as the SDK no longer included the graphic binary.
  • Save it and reboot the devices to take effect. Wrong cache location causes infinite SpringBoard crashing.

Purpose for iOS 5 devices

  • Add missing binary at /System/Library/Assistant/UIPlugins/SpringBoard.assistantUIBundle/SpringBoard

Purpose for iOS 6 devices

  • Add missing framework binary at /System/Library/PrivateFrameworks/AssistantUI.framework/AssistantUI

Purpose for iOS 7 devices

  • Add missing framework binary at /System/Library/PrivateFrameworks/AssistantUI.framework/AssistantUI (Applied to SiriViewService.app and SpringBoard)

Connecting to Server

Holding down the home button for a second should activate the Siri tray at the bottom of the screen (iPhone, iPod and iPad running iOS 5), or at the area close to home button on screen (iPad running iOS 6+), but saying anything will make it say it can't connect because the server rejects any query from these unsupported devices. This is due to the device requiring an identifier that the Siri servers generate every 24 hours for Siri-capable iDevices.

Changing Server

SiriProxy can overcome the server connection issue if you have access to Siri capable iDevices. 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.

Bypassing Authentication

Alternative to dealing with SiriProxy, it's also possible to trick the Apple server that you are using a Siri-capable device by simply faking device model that the system would include as a "header" to send to the Apple server (method -[ADAceConnection _startConnection] does that). It could be achieved this way: SiriAuthFix.
