#Integrating RubyMotion and the iSpeech SDK
As of 19th July 2012, RubyMotion has a couple of issues with external libraries as I discovered when trying the integration, thanks to Laurent, the architect of RubyMotion and with some prompting from Stéphane Wirtel here is the issue and resolution including the code to make the iPhone speak.
Firstly setting up the app, assuming you've already copied the files you need into your vendor/iSpeechSDK directory this is the code needed in the rakefile as per any normal library ...
app.vendor_project('vendor/iSpeechSDK', :static, :products => ["libiSpeechSDK.a"], :headers_dir => "Headers")
