Eichhoernchen is working on an open-source Siri server. Not a SiriProxy server, but a full Siri server that replaces Apple’s own Siri server. The server is currently in a very early version and is not yet ready to be used. But if the server gets updated, it might someday make SiriProxies obsolete.
By now, you probably all know that you can get Siri on your iPhone 4, iPod Touch and even your iPad with Spire. The problem is that you need a SiriProxy with iPhone 4S keys to use Siri. The reason behind this is that Siri streams your voice to Apple’s servers everytime you say something. It then processes your voice and returns text. But without keys from an iPhone 4S, Apple’s server won’t process your request.
What the open-source Siri Server does is simple: It doesn’t send your voice to Apple, but to Google’s Speech-To-Text API. That way you don’t have to worry about authentication, because you are not communicating with Apple’s servers at all!
While this might sound very simple, there are a couple of problems the developers of SiriServer are currently working on. The first one is that the Google Speech-To-Text API only allows commands shorter that 10 seconds. If you would simply cut the stream in pieces every 10 seconds, you might get false results (Instead of “What’s the weather like?” it would be “What’s the we” “ather like?” and Google couldn’t convert it correctly.) One possible solution for this problem would be to analyze the audio and trying to find short silence periods. The Audio could then be split into two parts without cutting off words.
Another problem is the processing of the commands. If you ask Siri “What’s the weather like?”, the server will match your sentence and know what to do: Send you the forecast for the next few days. It then has to get your location, request the forecast from another server and then send it back to your phone. The open-source SiriServer has to learn all of these commands. This means the developers have to program every command Siri understands. And this takes a lot of time.
We will probably have to wait a little longer until we see a working open-source SiriServer, but this project looks very promising.
