Siri Server Core
Do you like this?
If you like this piece of software you can help me by donating, I can afford new devices and so get deeper to the core of all of this. Make it even cooler. Or if you just want to give me a little credit for my work. But don't worry the code will remain free, you don't have to donate.
What is this?
This is a very early version of a Siri Server (not a proxy).
Apple's Siri is an voice controlled assistant on iPhone 4S.
With jailbreaking you can install it on other iDevices. However, Siri needs a server to communicate to do the speech processing. Apple only allows 4S devices on their servers.
This project tries to recreate the Apple Siri Server to use it with other iDevices.
You don't need any 4S keys to make it work, as it is independent from Apple.
It uses Google Speech-To-Text API. And therefore we are currently limited to commands that are shorter than 10 seconds (maybe we can overcome this).
Setup, Notes and Instructions
Install audio libraries
On Linux simply install it via you packet manager e.g. (or see instructions and note for OS X):
sudo apt-get install libspeex1 libflac8
On OS X download libspeex and libflac from the websites above (the sources, not the binaries) and compile and install them, or simply follow the following steps:
wget http://downloads.xiph.org/releases/speex/speex-1.2rc1.tar.gz tar -xf speex-1.2rc1.tar.gz cd speex-1.2rc1 ./configure make sudo make install cd .. wget http://sourceforge.net/projects/flac/files/flac-src/flac-1.2.1-src/flac-1.2.1.tar.gz/download -O flac-1.2.1.tar.gz tar -xf flac-1.2.1.tar.gz cd flac-1.2.1 ./configure --disable-asm-optimizations make sudo make install
Note: you can also install libspeex via MacPorts, but libflac is not available in 64bit through MacPorts, to make it build with 64bit support you need to supply
--disable-asm-optimizations in configure of libflac to make it compile
As this project is coded with python you need a python interpreter (this is usually already installed). I work with python 2.6.6 and 2.7.2 and both work.
You also need some python packages to make it work:
pyOpenSSL is also a requirement for twisted, so installing twisted will already force an installation of pyOpenSSL.
On a debian based system twisted can be installed via apt:
sudo apt-get install python-twisted
On OS X you can install it via easy_install (
sudo easy_install pyOpenSSL twisted) or via MacPorts (
sudo port install py27-openssl py27-twisted)
You also need to generate certificates for this server, they must be placed in the keys/ directory, there are dummy files to show you the correct names.
Installing API Keys
To allow plugins to reuse API keys, there is an apiKeys.conf in the root directory of the server. (Note in this git there is only a dummy file -EXAMPLE)
The general format is as follows:
The apiName is usually printed in error messages when you miss a certain API Key.
Running the server
Now you are ready to go, start the server with:
You don't need to run it as root, as we use https port 4443. If you want to use another port use:
python SiriServer.py --port [PORTNUM]
Note: for ports <= 1024 you need to run the server as root (e.g. via sudo)
If we had the mid 90s this section would glow and sparkle to get your attention. There are some errors that might occur even though you did everything that was written above...
The server just crashes after a SpeechPacket
You are running Linux right? Probably debian?
There is probably already a libspeex on your machine which is optimized for SSE2 which does not work with python (reason???)
Check if there is a
Option A: delete it (there should also be a version in /usr/lib if you installed via apt, or in /usr/local/lib if you compiled by hand)
Option B: ToDo
I cannot get a connection from device to server
Do you access your server over the internet? You need to setup your firewall and NAT to allow traffic for tcp port 4443 directed to your server Do you have a local firewall on the machine running the server? Also check if tcp port 4443 is allowed for incomming connections You must also make sure to setup the corret server and port in the spire configuration:
There is something with SSL in the error
Have you installed the ca.pem file on your phone? Do you have more than one CA certificate installed for the same domain?
=> Try deleting all certificates on the device and install the one created by gen_certs
Can I somehow verify the correct certificate? YES!
start siriServer.py, then take your ca.pem you think belongs to your servers certificate and run:
echo | openssl s_client -connect [DOMAIN]:4443 2>&1 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' | openssl verify -CAfile keys/ca.pem
Make sure to replace [DOMAIN] with the actual domain of the machine running siriServer.py (e.g. an IP address)
If your ca.pem matches your server certificate you should see
stdin: OK as output!
OK, what else? We can also setup a small test server using openssl to check if SSL is working (and to check if the iPhone correctly validates the server certificate):
openssl s_server -cert keys/server.crt -key keys/server.key -accept 4443 -state
When you run this (SiriServer should NOT run) it opens a basis server on port 4443 using your servers certificate.
Now you can connect with your iPhone as if you would use Siri (of course Siri won't work, we are just testing the SSL layer) It should output something like this, note the Ace http request near the end:
